UStorSrv.exe is part of U-Storage Tools, a software package that enables data to be encrypted on USB flash drives. It comes prepackaged with flash drives from a number of manufacturers, including Imation, Sharkoon and others. Use of the encryption feature is optional, but if it is used, you won't be able to access encrypted data without this software.http://www.neuber.com/taskmanager/process/ustorsrv.exe.html

rate3 For my case this file was installed by Transcend USB Flash Drive software CD (I suppose, it implements "PC Lock " function and so).  See also: Link   Desummoner
rate2 Part of a package called "U-Storage Tools". It's apparently used for supporting encryption on USB flash drives. Found it on my system after having used a friend's "Sharkoon Flexi Drive" which had encrypted data on it. Had to start a "SHARKOON.EXE" off the drive to be able to enter the password, and that's probably what installed this "UStorSrv.exe" as a service.   staaki
rate1 An application for sync with particular brands of flash storage disks - an extra feature not needed when using windows file wizard   Alienangel
rate3 Installed by Imation Disk Manager II for accessing encrypted partitions on OTi USB Keys  
rate3 it came with my Sharkoon USB stick ( never had it before installing sharkoon) ...For some reason it's trying to get access to the internet. I blocked and it still works fine   Peter Berndsen
rate3 Also installed & used by Imation Disk Manager III.exe for their USB Drives, if worried Firewall block the sucka!   rand0m!
rate0 I found it after i bought a USB memory stick with encruption partition as part of its features.   George P.
rate5 decompiled it and found that it an IRC bot running system32 director   Andrew
rate1 I believe it's from Imation. I use USB mem also.   The Spartan
rate3 It came with Imation Disk Manger IV and prioty normal, doesn't give any distinct problem. But can't be terminate in Normal Window mode. May be in Safe Mode.   Ceogeek
rate3 I believe I got it after I used an Imation Flash Drive - which has a partition which has been encrypted and requires the LOGON program to be run from it, when you want to access that particular partition on the flash drive.   Viji
rate2 Got this with USB flash drive with encryption   MikeC
rate2 Installed as part of support for EasyDisk USB storage device   Ian Dobinson
rate3 It was installed after the USB stick was used.   Chris
rate1 USB storage driver   swiebertje
rate3 It showed up in conjunction with installing Imation flash drive executable for password encryption/protection. The software works just fine with no internet connection, and I select "Deny" when ZA Security Suite Alert pos up   JJB
rate5 Nasty bugger pounding my firewall with a port scan (looks like a syn-flood). SpyBot, AdAware & GIANT (Microsoft) do not rate it as "spyware", nor does McAfee see it as a virus, but anything that slams a firewall has got to be suspect. Disabled the service and scanning went away (from that machine). Now onto the next spyware challenge....   The Colonel
rate3 Installed by my Imation 128 MB USB memory stick   H. Taylor
rate0 It loaded when I installed my Imation memory stick   Timm
rate0 Nothing Yet, McAfee did not recognize the application so I blocked all access for now  See also: Link   Jed
rate0 Encryption software for Dick Smith USB Drive   Shane
rate0 I too got this after using my Imation flash drive with a secure partition. So that seems the most common explanation. Thanks   gtoland
rate4 This program installs itself with plug and play USB drives, including Imation, and if you have Norton Internet Security, it will block it and ask you what to do, to be safe, you should "Always block connections to this program on all ports". Your USB drive obviously does not need an open connection to other computers or the internet, and so this could be an malicious infringement program from the makers of your USB drive.   Mark
rate3 I believe I got it after I used an Imation Flash Drive - which has a partition which has been encrypted and requires the LOGON program to be run from it, when you want to access that particular partition on the flash drive. You can set your firewall to blockk its access to the Internet - as it does not require it. This causes no harm to its operation. Cant figure out why it would want access to the Internet though. Anyway, it comes from a reliable manufacturer - Imation - so, am happy to trust it on my PC - but will block it from the Internet.   Viji Rajasundram
rate2 I got it with my Imation 1 GB USB drive, you can remove it with the freeware autoruns   Poda
rate3 This process appeared immediately after the first time I used a new USB flash drive by Simpletech, the Bonzai Express. The flash drive came with a utility to allow password encryption and this program probably included this process. The process is not listed in msconfig under startup, but was found as a running process immediately after boot up, by Hijack this!   hayhaypaula
rate3 I believe it installed with my imation USB thumbdrive. I want to know why it's trying to access the internet.   batteryacd
rate1 I try to understand all the process running on my machine by asking ZA to allow or not the process running. From the comments I have read in your list, I suppose it is part of Imation disk (But why this process want to access internet ??). I don't know! However I have it on my computer for two years now and I nevergot any problem. So I suppose it is not dangerous.   micmond
rate1 usb memory card reader   Lexxus
rate1 i also have this thing. i comes since you start the application called u-storage.exe   hiroki
rate3 Appeared after partitioning my Imation USB pen drive.   The Bernoulli Effect
rate1 Installed by Imation Disk Manager II for accessing encrypted partitions on USB Flash Drives   dlloyd
rate3 Imation USB Flash Drive Disk Manager, will attempt to listen for connections from other computers (all local network adapters) - TCP inbound.   Julian
rate4 It came with card reader   mariano
rate0 i've got an Imation flash drive too, that must be what it is, thanks   myself
rate3 I got this with my Imation flash drive stick. I reformated the stick which erased the "OTi Content Service" program (which is a log file) so I did not have to keep deleting it out my system32 file every time I put the stick in my usb port,   Bet It All Die Broke
rate0 Seems to have arrived with Imation Disk Manager - Killed proess and renamed ustorserv.exe in c:\windows\system32   davidson
rate0 It's obviously a USB Flash, Jump, Thumb, or similar type device that auto installs as a Windows XP Service. It can be [Disabled] by Right-Clicking the 'My Computer' Icon/Menu choice, and Selecting the 'Manage' menu choice. Just click the 'Services' , click to change the view to 'Standard', Scroll down,, highlight the 'UStorSrv.exe, then click to 'Disable'. After it's disabled, Restart the PC, then Search for the "UStorSrv.exe", Delete it, and Empty your Recycle Bin. You must also edit the 'Registry - via "regedit", Find each folder, or entry, and delet as well. Finally, delete from win dir.   Thennism
rate0 Found it on a DSE usb drive, looks harmless but not sure  
rate2 Likely related to U-storage app for memory stick. Curious thing is that software is on the PC for over 2 years. In that time there have been no changes in how memory stick is configured. And only now an .exe with this name tries to get access to internet. Last time the memory stick was connected to the PC is weeks ago, PC has been rebooted countless times since then. Running McAfee antivirus and F/W, all up to date.   Stapel
rate0 related to "imation" USB flash drive   Janet
rate0 Came with the Transcend JetFlash USB Drive utilities.   Gab
rate1 I also have the file and a Imation Flash drive which I installed on the date when my Anit Virus first detected this program. I don't know of any vulnerabilities or subsequent exploitations.   Debgary
