| | there is a way to destroy the thing get into the registry editor and find: integrated search. delete all the integrated search values you see ( dont skip any) then go to program files and an istsvc folder should be there, delete that and the pain is all gone |
| cubic_globe | ad-aware and it's gone |
| | Its a pain in the backside.... Use safe mode.... to boot and delete it |
| kais | even when you delate it with one of the spy abattment softwear it comes back, it means that it makes the software thinks that it's delated but it's just an illusion |
| kais | comeback even when deleted |
| Browso | spyware which keeps reappearing after being deleted from computer. I have tried adaware, spybot, hijackthis, trojan hunter to get rid of file but it keeps reinstalling itself as long as there is an internet connection. |
| | It sucks it takes u anywhere he wants, system can get stuck from memory overloaded |
| Arnie | Spyware , Slows your Pc |
| David Baptista | Made by a company called integrated search technologies. Can be removed by running add remove programs and then running add aware to remove registry entries |

| Remi | hard to remove |
| Magnús Karl | Spyware indeed...! , you can remove the spyware by using "Security Task Manager" and end the process and then delete the file :) |
| Sponge Bob | This also stopped the anti virus software, set it to manual and prevented it restarting |
| Bill Saunders | Trend Micro identified it for me. I pulled up Task Manager and terminated it (was running). After that, I was able to delete it. I now must change the jumpers on the affected drive and re-install it on the bad computer for retest. The symptom was denial of service: could not reach any internet pages.... |
| Matthew | if using xp- Ctrl + Alt + Delete, find it in processes, right click and say "end process", then delete the file in explorer. |
| Evert | He wont leave my comp :P |

| Wim | it slows down your computer |
| | Hard to get rid of |
| Okan | ad-aware does not remove it at all. |
| Christine | It causes lots pop ups. I used Spybot, Adaware and Pest Patrol to remove it. I also manually deleted every reference to it in the registry and deleted it from C:\Program Files\ISTSVC\istsvc.exe (the file and the folder), but when I rebooted, it was there again!! This is a real pest the first time I have had this much trouble with removing!! |
| Don | Don't know how i got it. Tried to delete from windows then from cmd promp. finally used Task Mgr to stop process then was able to delete containing folder in Program Files. Also went into registry and removed exe files. Hope I don't crash. |
| hclark | it's annoying - lags my system down and pop ups |
| Deb | I can't delete it, even with the suggestion mentioned above - help!!! |
| Mark | It plants itself on IE and has a nasty habit of rehabitating spyware upon each reboot. If you run adaware or like programs you will see reoccurance of the same spyware imbedded into your system. It plants itself into numerous registry areas and even when removed it has hidden files to replant itself |
| Coaster | its spyware |
| | It is difficult to remove and increases disk I/O load causing dangerous thrashing. This spyware has killed two laptop hard disks singlehandedly at the office. |
| matt | it wasnt there when i bought the computer and now my computer is jacked |

| Boris | Can't get the program to remove this program |
| A | I found it, and I can't even delete it. I had to end many tasks that I randomly chose before I can delete it. A nuisance |

| Jaybee | Tenacious a real pain |
| | I tried deleting the folder "program files\ISTsvc" which contained only the exe-file, but it was running. Therefore I used alt-control-delete to start taskmanager and stop it manually. I was then able to remove the folder, and I hope it won't come back this way. |
| | displays a lot of popups. Remove it by killing the process in the task manager, and then use HijackThis to remove all associated entries. |
| bati | verlangsamt rechner und rechenleistung, mittels regedit und anderen programmen nicht löschbar; installiert sich nach löschen der exe datei immer wieder neu |
| Nielz | I dont know what it is but i cant delete it manually |

| losingmyself | cannot be removed by adaware, GIANT spyware, etc - continues to attempt to install itself even after it has been "removed", insterts a value into registry that makes it run when you start windows - installed a toolbar and gave me popups on my otherwise popup free comp - check out the link for symantec's removal tool, if that doesn't work you'll have to delete it from registry manually, follow directions on link page See also: Link |

| benjamin042 | keeps bringing on popups could cause a crash on your system |
| WiLiWiLsOn | paralyses your computer by using all of the virtual memory - stops regedit, task manager and prevents memory dependent virus/firewall systems from operating |
| Tom Haring | not very much, but the fact that it is very difficult to remove and has a task htat is invisible makes it very suspicious. I didn't give the program acces on the internet with zone alarm. That made the computer slow. |
| Spybuster | Took me a lot of time. Tried Adaware and Spybot. After using them multiple times I finally got it deleted. I also tried the removal tool 2 times |

| Jared | almost imposible to fix/delete hijackthis, ad_aware, spybot, Mccafe, Norten, delete comand... none of it works. still looking for a solution |
| Danny | Nothing, only it pops up, when i run ADaware and "AD" says it's a spyware... |
| tam7 | It is created in \program files\istsvc folder. It works as a backdoor for downloading various programs (including viruses) in c:\windows\temp, then tries to execute them. In my case it came with another program file which installed itself in the root directory. Their giveaway aspect is their date/stamp, which is the same. You can delete both manually when restarting the computer in DOS mode. See also: Link |
| Gus | ISTSVC use file PHVNOLP.EXE (hidden file alocated in c:) to modify Registry key and R. value |
| | Can't be deleted, i tried to end the process in taskmgr, and then quickly delete it, but didn't work, still in use somewhere. i'm going to try Security Task Manager now! |
| | newly researching it but I suspected it was spyware. Will delete |

| Connie Lersch | it also execute a print command automatically on start up of your syste. |
| MM | It is a very intrusive pain in the neck, delete registry keys and files in safe mode |
| nik | interestingly, this spyware managed to start IE from within Firefox and then installed itself via that. |
| dexy | simply rename the exe file then delete the bas**rd, then go in regedit as shown above to kill the registry items |
| Andrew Derrick | Wird nachgeladen durch "istsvc_updater.exe" diese Datei versteckt sich oft im Benutzer-Profil oder in einem Temp-Ordner. |
| | Awful spyware. You have to end the process first, then remove it from Add/Remove programs. Use Ad-aware to get all the other crap. |
| ncd | Used process explorer from sysinternals to find out what the parent process was and killed that (it was respawning the istsvc.exe process). See also: Link |
| Onkel Toms Hütte | Legte mehrmals mein System lahm, störte meine Internetverbindung und startet sich trotz mehrfacher Entfernung immer wieder neu. Deinstall + löschen dringest empfohlen. |
| Belarc | It installs multiple proceses in the Registry making your system unstable. It is dangerous. My laptop was in kind of a mess and I had to work on it for a day to resolve the problem. |
| jako66 | kann nicht gelöscht werden, VScan erkennen diese als Bedrohung machen aber nichts. Datei startet Progs im Hintergrund. Sehr gefährlich im Internet, da die Automatic und der Start übernommen werden. |
| | Loads as a process. Must kill by Ctrl-Alt-Del, then find process, kill it. If comes back then kill bwnaicv.exe process, and then kill istsvc.exe again. Spybot and Ad-aware only temporarily remove it. |
| Vladimir | My BitDefender antivirus made a report that this prog had tryed to write himself into startup menu. I've deleted the folder with this prog, and my Internet connection failed. It tampered with my registry, I think. |
| Ryan | In order to successfully remove this beast, you need to kill istsvc's parent process first, "ukipvm.exe" - this is usually stored in "C:\Windows\ukipvm.exe". Choose to kill the process tree for this, and then manually delete it and "C:\Program Files\ISTsvc\istsvc.exe" using Windows Explorer. |
| speedy | This file realy bugged me for hours , you may think you would think of it straight away i downloaded mal ware programs, tried everything but i didnt think the file would be in the add and remove section in the control pannel.I deleted it from the add and remove section rebbooted pc and ran ADaware and i finaly got rid of it simple but it works |
| JJ | It's really annoying mostly, makes the computer lag quite a bit at times and keeps giving me pop-ups. The first time I ran the tool to remove it, it claimed that the program was not on my system (It was, I saw it running with my own eyes) so the tool may or may not work for you. I'm running it again after deleteing every found source that I could come across. |
| Florian | I just bought a new computer and even w/ Norton Anti-V. I can't remove this file. When I tried to do this manually it also will not work claiming that some other program is using it. After entering " Task Manager" and ending the - -.eve I could still not delete the pogram or directoy which it had installed on my computer. No as for Active X (which i have read on the German section of this site may have silently installed it) |
| Idon'tlike computers | Go to fee downloads.com, download adaware, (you will find it toward the bottom of the page), run it in safe mode. You get to safe mode by restarting your computer and pushing the F8 key while your computer is restarting. Don't hold it down, just keep pushing F8 until the screen comes up and asks you how you want to start your computer. Use the up and down arrow keys and point it to safe mode. Now run adaware and restart your computer. See if that works. |
| william r moore | first run this program from nortons.....then open task manager by pressing ctrl/alt/delete buttons till it opens...then find istsvc.exe.right click it and end process..x out of task manager..then open add/remove program files..find istsvc.exe..and remove it...then open up enternet explorer and empty tempary internet files..offline files as well..clear history..delete cookies...then reset your home page to whatever you use..and click apply....this should get rid of this pest...

| Miles | Its annoying as all get-out i cant kill the blasted thing, i ve manually picked every file out and deleted them but they just keep coming back!, grrr |
| ryball | it keeps installing itself on the system, adaware does not remove it properly, must delete it out of your program files and delete all of your temp files. must end process before removing from your progam files |
 pelle | on this link to the parasite himself you get rid of the virus See also: Link |
| Zacar | go to configuration and then software. There you can delete it. |
| shorty.deluxe | komplett deinstallierbar! "C:\\programme\Istsvc\istsvc.exe /remove" |
| Simon | The removal tool failed to find the spyware. I followed the advice given by a user called dadclass (follow the link). Worked like a charm. |
| Axl | Hard to remove but possible, but I know the answer! Download Adaware and clean your disk in "secure mode" then Replace the C:\Program Files\ISTsvc\ cataloge and create a unharmfull executable file instead and name it istsvc.exe. But make shure that the executable is small and selfclosing othewise will your memomy be drained after a while. Then write protect the cataloge and the newly created file. This would solve the problem even for future atacks! Good luck |
| freakedout | Resurrecting freak. It slows down my PC performance. |
| | It is now preventing the installation of Mcfree |
| Pete | Trojan as Identified by Antivir. Spyware/adware as Identified by Spybot/ Ad-aware. Restarted my computer due to constant freezing, cpu would not restart without dsl connection being unplugged. spybot got rid of it temporarily until i re-established my dsl connection. Look in your C:\Windows\Prefetch directory if you have one. it is there with a .pf extension after the normal istsvc.exe filename. I think that's how it re-starts itself. As of yet, I haven't been able to delete it permanently. |
| BrettM | constantly reenters itself into running processes, which is why you cannot just delete it. you need to cancel the running process, then run adaware...it will work. I run mozilla for my default browser and do not get many popups at all. |
| Sean | i hate it, i even tried my Move on boot program and it still came back, when you end its process it comes back too.. |
| Ben | setzt Arbeitsspeicher herunter |
| | It's not dangerous, but it is annoying. Quarentine it if you can. |
| yehyehyeh | nobody likes it.....everybody says it should be removed. Security Task Manager removed the file. Thank you. It will cause damage if left unattended on your computer. It is hard to find spyware that will remove this file. You have to stop the task before you can delete the file. Use Security Task Manager!! |
| Jess | Dunno how I got this; very annoying...I'm constantly getting a "Server is Busy: Switch To, Retry, Cancel" option box; cannot close it, cannot hit cancel... |
| LoosJ | Wird als Prozess gestartet und kann nicht gelöscht werden.Explorerfunktion im abgesicherten Modus ist nur für eine Sekunde verfügbar.Über DOS-CMD-Fenster kann es gelöscht werden. Beim regulären Neustart ist es wieder da. Wahrscheinlich von einem Dropper abgeworfen, der sich nicht finden lässt, bzw. nach seiner Aktion selbst löscht. (Exploit ?) |
| Phat Bastard | C:\program files\istsvc\istsvc.exe is recreated and executed every time I reboot |
| zero | related to spyware |
| Craig Andrews | Running task mger you can see ISTsvc is running but once you stop it it will pop back because there's a second program running in processes keeping it in use and preventing you from deleting. I found the second program cprjv in windows folder. In task mgr stop the second file, delete it,, stop ISTsvc and delete it. |
| Tim | I removed thru add/remove programs, and then ran adaware se, and also spybot, and restarted pc, remember to remove first thru add/remove programs. Spybot and adaware removes all of this. |
| ajay | it's dangerous and mainly crash internet explorer. it shows adults pop-up |
| ace_balasador | funny thing i used firefox for months now then this popped up... opping IE instead LOL |
| Stephanie | I bought software to get rid of it, and it seemed to work, but once i restarted my computer, it was back again!! Spyhunter doesn't work |
| hartt | Delete failed until I did: 1- task manager [End Process] on istsvc.exe 2- deleted folder on c: drive 3- ran AdAware |
| | this is the worst file I have EVER seen! I have deleted all reg keys pertaining and deleted it in safe mode. I still...cannot get rid of the file in program files.! |
| | Still comes back even after deletion with the Symantec tool. I've tried Spytbot, Adware, Symantec's tool and Microsoft's Adware beta program. It keeps coming back! |
| Dagurasu | Very nasty. But there is a way to get rid of it that I found in the Lavasoft Adaware Forums. Basically, there is another process running that prevents you from deleting istsvc.exe. You have to go into the Task Manager and figure out which process is the one related to istsvc. You can do this by googling all the process names. When you find the right one, end it. Then you can end istsvc and delete it. Then run Adaware, HijackThis, etc. Reboot and you should be OK. |
| Sherri | very problematic--in my case it had an automatic backup file in quarantine; deleted from here and possibly a couple of other spots in adaware and finally permanently removed |
| Jacob aka "Computer gEEk" | To remove: 1, Uninstall all toolbar-programs and all programs connected to the virus(You'll se when you are in "Add/remove programs"). 2. Remove "tydxrvn.exe" (C:\WINDOWS\tydxrvn.exe). 3, remove "istsvc.exe" (C:\Program\ISTsvc\istsvc.exe) and now its gone! |
| 3Tech Computers | Spyware/adware file or trojan easily removable with proper tools See also: Link |
| Hans Krijgsman | It will be removed by Ad- aware, but not complete. After a reboor it installs again. |
| Syahril Adar | Be careful with this unwanted file. It causes your PC crashes and difficult to shut down or reboot then your PC should be reinstalled. |
| Aaron Tilley | can be removed. restart in safe mode (press F8 key on reboot) should be under C:\Program Files\ISTSvC. just delete it and then run a scan for anything containing istsvc and then delete all of t hose files |
| well wisher | My information is that this is spyware and must be removed from your computer |
| KreenDurron | Im using XP home edition, You can't just simply end the prosses in task manager and then find the file and delete it. I've tried this and it will continue to tell me "Cannot delete Istsvsc: It is being used by another person or program. I've also tried using the registry editor Doing all this from Classic Liz's suggestion.... (RUN: REGEDIT (HKEY Local Machine, Software, Microsoft, Shared Tools, MSconfig, StartUp Folder (GET RID OF ISTsvc FOLDER!) Then delete the folder out of C:\Program Files. ) But The file wasn't found using that path, it wasn't in c/documents... |

| pcp101 | creates pop ups and wants to download stuff |
| George | It is detected by ad-aware, spybot,... and these programs can be used to delete the program. However, after a few seconds it is installed again by other programs that are not (yet) detected by spyware removal programs. I identified a program called "lnxnyavf" that kept on installing "istsvc", but I expect that ISearchTech (the creator of istsvc) will come up with different names every day. |
| Sayun | Pain in the ass program! Use MozillaFirefox or Opera. Using Explorer to surf the net, is like driving a car with sugar in the gas tank. |
| kosta | sehr hartnäckig |
| jaime | prob. got it from downloading porn off limewire- sometimes you are directed to a site when you try to play it. i have removed it but it came back |
| Chris | This is part of that little search bar located just above the windows system tray clock. It drops into a folder under Windows called isrvs Which is hidden but can be removed in safe mode. See link to remover which does remove it. See also: Link |

| | spybot would not remove it. used add/remove programs |
| | it create lots of pop ups, and installed multiple programs on my compy. i hate it. |
| | It uses a 2nd process to keep itself alive, goto start- run- type: regedit- goto HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run - there should be something with 5 random letters/numbers with the path to the 2nd file in it. I hit CTRL+ALT+DEL, ended the task (it was named something like pcjb or something) and the istsvc.exe thing, and haven't seen it since that time. |
| | hard to erase program. it pops back on everytime its removed. i uninstalled the program that it attached to still came back. used IE residence came with the Spybot S&D finally stopped the program from creeping back into registry problem solved! |
| LinuxGeek | Is this not illegal...Damaging a person's property with your unwanted software? These guys need to go to jail for property damages, I think. Meanwhile, it doesn't do anything if you run Mozilla Firefox or the full Mozilla Suite. |
| | Seems to like stopping you sound too, Still trying to solve problem...is in Add remove...however not too sure how much help that was. Seems to install other virus'/spyware. |
| fiona | keeps coming back even though you delete the files |
| challad | this file has prevented me from logging onto the internet and/or not letting me login at all from my home address. However I am able to login from another location. Strange!! |
| jetreaver | to remove istvc, find the folder istsvc "c:\programfiles\istsvc" and then rename the folder... then manually delete the istsv.exe |
| Kai | Removal instructions: br 1. End process in Taskmanager: istsvc.exe br 2. Use Security Task Manager to locate and delete the file br 3. Search registry for istsvc.exe and remove all keys |
| Rick | Adult content high jack, browser redirect, possible downloader or downloaded with other backdoor. spybot finds and adaware finds also but may not remove root cause. This has defeated the Norton antivirus and symantic.386 file is missing needs to be relaoded. In dos mode to progra~1\istsvc\istsvc.exe and del the file then rd the directory. Rerun Spybot and Adaware then reinstall AV software if needed. Symantic also has a Fixistsvc on site. Bit of a nasty so say the least. |
| | Extremely invasive. It manages to bury itself, and continually come back up, no matter how many times it's crushed. |
| Christopher | I have been frustrated, because the anti-spyware programs do not seem to remove it permanently. I wonder if it tracks your IP and attempts to install itself over the net if it isn't there. Anyway, I killed the process like everyone else has, went into Visual Basic and made a dummy executable called istsvc.exe that does nothing but display a message box. Then I set the security to deny all rights to the file, so that it cannot be overwritten. I have yet to see that message box pop up and the dummy file has not been changed, so I have effectively disabled the mechanism albeit in a kludgey way. |
| Michael McMullen | This thing is horrible. William thank's for the Symantec link.. Arg this thing is just a P.O.S. if you ever get it Goto the link that William R said and use their tool (or do it manually) See also: Link |
| raisin | There's another exe that install and run istsvc.exe. For those of you who cannot remove it even with spyware cleaner, try windows security task, check the istsvc process, then check what caused it to run. Delete the program that runs istsvc. Also there are some files placed in temp. internet files, be sure to delete them too. |
| Dvda | spyware for marketing, really hard to remove reinstall itself |
| Troublemaker | A pain to remove, but not impossible. Easy way is to press F8 to get to the boot menu, then select Command Prompt. Once there, do a cd \progra~1\istsvc then del *.* - THAT'll fix it's wagon! |
| Tony | is a pain to get rid of. Go to C drive, Windows folder, and delete Janet.exe This is what it runs through and will get rid of it |
| Pierre | Whatever it is, it's a pain. It slows the computer and messes up everything. Went through all "scan" and can't delete", then went into "Add or Remove Programs" and got it! For now anyway. |
| orion | strangely, microsoft's anti-spyware seems pretty good. it got rid of istsvc.exe with no fuss, no muss, no reboots, no safe-mode, etc. See also: Link |
| | can be simly uninstalled! Control pannel -- add/remove programs :) |
| Dave. | Keeps installing itself every time i'm on line. Ad-aware delates it on re boot. but returns every time i'm on line. Causes loads of pop-ups, a real pest. |
| Stan the man | Annoying when windows Xp starts. Removed it with Adware Away. Easy folks, No Sweat |
| PeggyHHH | This programs knocks my computer offline several times each day |
| Angella | I used regedit from diamondcs.com to find where it was located (you can't remove the registry key - once you find it, you have to ctrl-alt-delete to shut down the registry editor), then I rebooted and started my computer in MS-Dos mode, preventing the spyware from starting up with windows, and, using dos, went to the folder (cd c:\progra~1\istsvc will get you there) then, FROM THAT DIRECTORY (important so you don't remove necessary files) delete the files (del *.*). That doesn't remove the registry key (I haven't worked that out yet) but as long as you remove the exe file it can't run. |
| | This program has removed Windows Update from my system. I turned off my firewall, I turn it back on and it turns it off again. It has turned off automatic update, I turn it back on and it turns it off again. It will not allow me to access task manager. When I click remove in add/remove programs it fashes the approval screen so fast there is not way to click on it, I have tried a hundred times. It downloads so much stuff my system freezes.I've had to pull the plug just to get my comp to turn off.Thank you IE for this program as well as ISIB!!!! |

| Simon Gündling | Zum LÖSCHEN Bei win xp : den Task mannager1. aufrufen2.Prozess istvc.exe abschalten (löschen)3.Im Ordner Programme den Ordner ISTBAR löschen 4.bei Ausfühen "regedit" eingeben unter bearbeiten "suchen" anklicken "ISTVC" eingeben us ensprchende Werte Ordener etc. löchen aber aufpassen NICHTS falsches löschen kann schweere Folgen haben |
| Mansoor | To remove: kill the process tree of the parent proces that is usually a u* process (Use wintasks to look at all processes in detail). The Use Symentec Wipe Info tool to remove the u* process and the c:\program files\istsvc folder. Finally, use a good registry cleaner to cleanup the registry |

| bp | kept coming back after removal with spyware s&d, restarted and noticed without connection it wanted dial-up, so i used msconfig to take out some random startups. found that xcqppvyq.exe fixed it, so deleted, cleaned up with spyway s&d and it ain't coming back |
| Dennis Clarke | Nasty Adware - installs additional apps, too - use IST's uninstall process from their web site (see link) to get it out of your browser add-ons and start up, then use Ad-Aware to clean up the reg entries and left over files. See also: Link |
| Poindexter | More than most of these people posting here. Most people here can not complete a sentence much less explain the problem. Geez, it won't delete, computer won't reboot. Then why did you mess with it? get a pro involved.... See also: Link |
| Leo | Found this file (uhlxrf.exe) in processes of tsk mgr, ended it along with istsvc.exe, and then I was allowed to delete the file folder from C:\Program files. It is probably duplicating itself w/other processes. |

| Jerry Olson | I found this spyware on my laptop and it took me over a day to get rid of it. After many tries with NoAdware and manually editing the registry and trying to find tha associated task that reinvents the istsvc. I finally downloaded a beta copy of Microsoft Antispyware. I als took Axl's suggestion and created a dummy executable called istsvc.exe and write protected it. When I started my machine I got a message that told me the spyware was active and asked if I wanted to delete it. I said yes and I haven't seen it since. I am not sure if the Microsoft Antispyware would have caught it alone. |
| ed | i have tried every combination of steps i can think of to remove this thing. i've bombed my registry, deleted every file and folder in and out of safe mode, ran every program i can get my hands on (in and out of safe mode, before and after rebooting). sometimes it's gone for a few hours, but for the most part i can just watch it reappear in my program files after a few minutes online. i've got 6 spyware removal programs (all mentioned above) NAV, hijak this, etc. nothing is working. this is my second infection. in 8 years, this is the only one that makes me wipe and reload (TWICE now) |
| francis | This file is like the Borg, no matter what I attack it with it regenerates somehow. I have used Spybot S@D which removes it after a restart, but when i restart the machine again its back. It writes and re writes registry keys. it just will not go away. I have used Trend micro PC-Cillin and Norton Antivirus to remove this and i still have it. I am going to try some of the tips here to see if i can get rid of it |
| Erin | Annoying as hell. Ended process but it came back. Entered safe mode and deleted, but it came back. Norton Anti-V couldn't delete. Finally! I removed it! Was only successful after using "security task manager" and selecting remove and uninstall in that program, then Start - Run - Regedit - Edit "find - Istsvc.exe" and deleting all folders that were named that. Has not resurrected since. Try it. |
| zp | remove it using the Add/remove program thingy in yur control panel. then rename it to something else (istsvc.jpg for example) then run the file registry and delete the istsvc folder. after tt end the istsvc process from the windows task manager and then delete the file using explorer and empty the recycle bin. it works for me and i have not seen it in my task manager anymore so far. good luck |
| Christoph | Ist das einzige Programm das bei der meiner letzten Virenüberprüfung als riskant eingestuft wurde. Ich habe keine Ahnung woher es kommt, aber es geht zumindest nicht mit dem einfachen Löschen weg, da es von Windows verwendet wird. Insgesamt regt mich dieses verdammte Programm auf, da es unnotwendig ist! |
| GHD | It's funny: you can't delete it manually, the anti-virus and the spyware eliminator program can't delete it, but you can remove it using ADD/REMOVE PROGRAMS :))) !! But i think the best way to remove such "things" is to delete them in pure DOS mode !!! |
| dougie | I had to delete a 10k file call c:\windows\hsnqgh.exe before I could stop istsvc.exe from reinstalling it self. (also deleted registry entry to run hsnqgk.exe at startup) These bozo's should be taken out & shot!!!! |
| k | hard to remove I got rid of it. Listen folks just do what people are saying. ****go to task manager and end the program, then go and delete it from your files.**** hope this heps folks..it worked for me. |

| Bitwraith | This "Tool" bar is annoying more than it is dangerous & loads 2 processes in start-up named SAcc.exe & istsvc.exe + installed the following programs which can be seen in add/remove programs 1)ContextPlus 2)ISTsvc 3)MP3 Toolbar 4)SideFind 5)Surf Accuracy. Use Ctrl + Alt + Delete to open Task Manager , highlight the processes & select End Task for both of these processes then close Task Manager. I used a program called "Your Uninstaller" which automatically removes the registry entries with the programs & then I went to C:/Program Files & deleted the folders & restarted my computer. Gone!

| MiKe | This file runs threw 3-4 different processes. If you think that you can just delete you can't if you locate the Window System 32 folder they also install an .exe that will auto launch and download it again and again I have used Ad Aware Spybot and went manually threw safe mode, c-prompt and no luck. I finally got rid of all this by going and taking it out of registry(risky) then starting in safe removing the folders out of Program Files then C:\Windows has 2 files and System 32 has 2 too. after all this I had my IP Changed and it all seem to hold it back. |

| CC | You should also look for a program called SideFind in your C: Program Files, this program is linked to ISTsvc and may be responsible for downloading the file to your systems along with StatBlaster, Avenye Media files, SideSearch, 180 solutions msbb and Power Scan. |
