2. Run Windows Repair Tool to repair cli.exe related Windows Errors
3. Run MalwareBytes to remove persistent malware

The ATI Command Line Interface is a background task that communicates between ATI graphics card drivers and the ATI Catalyst Control Center program. It implements a system tray icon that allows you to access the Control Center to set and change various features of your graphics card, such as adjusting resolution and color settings, or configuring hotkeys. It is installed along with the ATI Catalyst drivers and is not essential to their operation.http://www.neuber.com/taskmanager/process/cli.exe.html 

If you want a detailed security rating about your cli.exe (and all other running background processes) read the following user opinions, and download the free trial version of Security Task Manager.

Note: Any malware can be named anything - so you should check where the files of the running processes are located on your disk. If a "non-Microsoft" .exe file is located in the C:\Windows or C:\Windows\System32 folder, then there is a high risk for a virus, spyware, trojan or worm infection! Check it out!

The cli.exe process provides a system tray icon from which you can perform diagnosis on any problems that you are having with your graphics card. If you have an ATI graphics card in the Catalyst range you should leave this process running. If you do not, you can safely stop this process.   Camo
Ati system tray function. Caused bad shut down problems and eventually damaged my hard disk partition (Win XP). Could never get the machine to get past 'saving your settings'. Eventually traced the problem to cli.exe through a process of trial and error. Using Catalyst 5.6. Appalling that Ati could release drivers with such a bad bug. Tuerned off the system tray facility and problem solved.   DRF (UK)
It is ATI Catalyst Control Centre... It could update automatic and things like that, but DON'T remove it from your list, it runs important driver info, f.ex Direct 3D or OpenGl.. It allows special configurations for your grafik system.   Thor Byrgesen
Safe, it's part of the new catalist drivers and the auto update feature started with Version 5.6 this control center alows acces to ATI cards for over clacking , settings ect. can be accessed by right clicking on desktop   armour

should i have 3 of them running?   tyler
It came with an ATI update   Kizer
up to 3 instanes running. Was very difficult to install upadated driver from ATI site and even installing .Net was not straightforward - you are constantly sent by MS sites to Update but that is no good if you use Firefox or something else The whole pack of dependent files is immensely complex almost like a mini-operating system and I suspect wide open to attack since there is no way most users will even know what they are doing. It also requires the .net system running which whilst technically very good brings its own new security iusses with it. All in all a headache for a "simple" graphics.   James, London
the file doesn't do anything bad..... but it does do anything good either.... you can change all the things it allows you to change by Settings Control Panel Display Settings, any time you want without the 18mb of mem and cpu use that these processes constantly use. end process on startup to save system resources for your own tasks.   Ganon

The problem is you installed the driver and catalyst software with out installing the 'Microsoft .NET Framework' first, I was getting the same error and couldn't figure out why, as soon as I deleted the redeon drivers, rebooted, installed the framwork stuff, then reinstalled the redeon drivers the error message never came up again, and yes the icon is now in the system tray, which was spoken about ny someone else///hope this helped for those in the future  See also: Link   Robert Spearman

Completely messed my hard drive. Caused it to shutdown unexpectedly and almost messed up one partition like the other guy said.   Mac
ATI Catalyst control center. You don't have to use earlier version of the driver. Simply choose to download the driver WITHOUT Control Center. Note that this still gives you the old video control panel in advanced display properties.   Florin Ular

ATI Catalyst Control Center, harmless but needs .NET Framework 1.1 to work   Meffy
A serious problem. I'm using the very latest version I can find of the Catalyst Control Centre(5.13), and for some reason, as soon as I start my computer, cli.exe starts up and then keeps spawning new instances of itself. It uses 100% of my cpu and just keeps going and going, until it finally hits about 200 processes or so and my computer crashes and reboots. I'm running on a fresh reinstall and I've ruled out a virus. If it's a bug in the utility then I'm really disappointed with ATI for realeasing this.   Joel

CLI.exe allows detailed adjustment of your graphics. It activates your adjustments when it starts with windows. I recommend allowing it to start with windows, then terminating it. Notice the "flicker" after the windows login screen? Thats CLI.exe adjusting from windows defaults to custom settings and/or ATI defaults, which are different than windows. One CLI.exe is for the system defaults, other for user adjustments. If a third, you are running the task bar icon for it as well.   ATI Master

Why does the Catalyst® Control Center require 3 “CLI.exe” files as well a “Preview.exe” file?   Tkass
people who have three instances running have 1 the .net server, 2 the .net client and 3 the win32 tray icon. if you kill your tray icon, it will drop to two, if you install the catalyst drivers that dont have the catalyst control center you will get 0 instances running, this passes information back and forward over, it's how .net comunicats. if you have more than three running, well, uninstall all versions of your driver and then see how many you have running, and this may be a virus. if your low on system memory you can safley turn it off   SmokeyA
You have 2 instances if the system tray icon is disabled, 3 if enabled.   Kiran

I experienced 2 Versions: The Version coming with ATI CCC and... some kind of Software, that isn't recognized by some AntiVir. In the Process Menu(Ctrl+Alt+Del) it shows up and disappears. This thing is stealing performance, and is not part of the ATI drivers, but hides there.   HurryCan3

This is associated with recent ATI Catalyst Drivers. One process runs to show the system tray icon. 2 others run to support the settings made in Catalyst Control Center. If you have 3 instead of 2 and want to get rid of one, disable the system tray icon. This can be done by opening Catalyst Control Center (might have to be in Advanced mode of it) and clicking Preferences, then unchecking "Enable System Tray Menu." In my opinion, you should only enable the menu if you constantly change your video settings, as it does provide somewhat quicker access to the settings. Otherwise, disable it.   kthxbye
The Catalyst® Control Center has been separated into different components (a unique instance of CLI.exe per component) because it allows us to tune the characteristics of the process instance to the type of component. One component is called the “Runtime”, which acts as a server to all of the other client components. The two other client components are the “User-Interface” and the “System Tray”. The client “CLI.exe”s are tuned differently to enhance performance; the “User-Interface” client is optimized to run for short periods of time, whereas the “System Tray” client is designed to run for l   Artimansee
The reason some have 2 and some 3... If you have 3 of them running it's because you have the ATI tray icon running. I suspect that you can reduce the number of these processes by using the msconfig, and then remove it from the start-up processes.   Teifu
Graphics processing takes memory. Go cry to a tree. I've seen as many as 5 instances running simultaneously, its nothing to worry about.   ant
cli.exe loads multiple times during boot, this causes a very long boot time because it uses a big amount of ram. Not harmfull but anoying   Petry Bosch
I got about 8 running at one time and this severely lags my PC's processes down. Perhaps its a new Virus with a Copycat name imitating that of an ATI driver.   Adrian
I get cli.exe errors when I play "mapple story"  
It weakens your systems security levell by causing memory shortages and slow bootup. I caught this file eating up more ports and memory then it should and it somehow slowed down my anti-virus programs ability to boot up therefore anything coulda executed or happened during that lagging time. I really don't trust this program and strongly suggest simply getting rid of it. Anything uncertain is just not worth it in my book.   stan vang

This is garbage. Is made on .NET framework, should be C++ like any good driver aplication and keep launching another cli.exe instances. Why a video card driver uses internet connection? And if you try to block using firewall you will lose game performace.   TheWarrior
Some settings in Cat Control Center will start another instance of cli.exe. If you have Hotkeys checked a second instance will run! Open Cat Control Center and disable hotkeys to take care of one instance. I believe specific Profiles will make another instance run also.   Wolfe
Just Kill the damn thing on start UP. If your not going to be messing with your 3D settings you don't need this. It is a control centre and does nothing unless you tell it to. Why 3 or even 2 running? I think it has to do with the video crash safety. Your video crashes CLI recovers but me thinks it starts another copy of itself afterwards.   Assweasel
I've killed it with ZA Security Suite because it was spawning multiples, no problems now.   Steve
on WinXP, causes machine to crash constantly, as evidenced by event log. very bad file. took me three days to nail down that this file was what was hosing my machine. ATI has been unresponsive to req. for help. : (   Paul
This process is sucking a lot of my ram, and i'm talking about 2GB of'em. No joke here. Will try to see wether the system works fine with this process killed (i had about 50 processes form CLI.exe in my task manager :(( ). If it does, i will delete it from the registry. Meanwhile i'm looking for fixes. Just as Joel says, it eats more than 50% of my processor and the whole friggin' RAM. 2GB? C'mon!   ACe
Accesses the internet when executed. Same as WGA tool from Microsoft.......   Dave
Is very easy to resolve this problem. Go to ATI folder and rename Cli.exe to CLI_Disabled.exe ( or something like that). Everything will work, and better then before. After that, Control Center woun't work so if you decide to make video settings changes rename it back to Cli.exe and restar the computer.   The warrior

The file isn't dangerous. It is OPTIONALLY installed with ATI's Catalyst drivers. It's simply the Catalyst Control Center which provides a GUI for adjusting settings on an ATI video card, but it isn't required for the card to work properly.   Quaxo
haven't seen anything bad, but nothing wierd's happening as of now   Jordan
I have 2 instances of cli.exe. I require it on start-up as I have a lowly 9200se and need all the 3D settings set to max performance levels. This requires CCC to be run. Without CCC, my benchmark scores are horrible. Quitting both commands in Task Manager frees up my ram, and the settings remain the same. I'm going to try & write some kind of automated command that will kill them once they have been executed in startup. Because I'm lazy ;)   Noz_S13
ATI Catalyst Control Center: It will create a substantially slower system performance. You can do an advanced driver install and uncheck the Catalyst Control Center portion, or simply go to Add/Remove Programs and uninstall catalyst control center. I have an ATI Radeon Express 200 vid card on an HP Slimline s7520n. It has 256MB of vid memory integrated. My frame rates in games improved without Catalyst and my page file has improved substantially. Unless you have a major card you dont need it.   Chris Moor
Wow, just randomly. THe CLI.exe process has been recreating up to 10 copies of itself, deleting them, and recreating them. This is causing my laptop with an Intel T2500 and 2GB of ram to be immensly slow.   Orien
Absolutely harmless! It is the catalyst driver kicking in. Gives you awesome graphics on an AMD 64 bit. People who say "It screwed up my machine" is wrong. Just get a little more RAM and you are sorted. Dont be so tight, if you want great gaming and graphics in general get just a bit more RAM if your PC is struggling. Maybe even your poor old intel CPU (lol! AMD all the way!), or maybe you bought a DELL (scum of the earth!) which put in the worst motherboards imaginable because all very cheap parts. Please note I have catalyst v6.3 installed on my athlon64 it opens ZERO ports.   keith23uk

CLI.exe is for the ATI catalysis control center. Is not needed exept if you want to have dual screen and uses about 15 megs of ram   Turnoz
This file cli.exe is started 3 times after the login-process in Windows. Every cli.exe listens on one port and it slows down my computergames. When running, my games are stopping for some seconds several times in a minute. Cli.exe uses about 35% of my cpu-performance when i run games. My opinion: The new ATI-Drivers are making games more realistic with a usage of more features BUT cli.exe slows down your system and when it's loaded you maybe think that your PC was infected by a "link virus" because of the slowdown process.   Daniel

I've just finished building & installing a new system. Checking out Task Manager, I see that CLI.exe consistently takes 50% of the CPU and then steadily ramps up it's demand on memory. Mem usage started around 6,000K, but when it passed 200,000K I killed it. Whether international or not, this executable seems dangerous to me so I've de-installed the ATI Catalyst Control Centre and that seems to have removed it for good. Now I just have to discover what functionality I've lost by removing Control Center..   Keith

As said before, part of the ATi CCC. Hoewever McAfee VSE 8.5 constantly reports about attempts to change counters in the network settings (\REGISTRY\MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Performance\Error Count) . A videocard driver should keep its filthy bits off my network counters. I use them settings for monitoring strange behaviours and bad network connectivity. It's not up to ATi to decide I'm not needing it. Basically CCC is a waste of system resources, and now it's tempering with settings it not need to be at, so I'd say bugger off.   Firefox

We have an ATI Radeon XPRESS 200 Series. 3 instances of CLI.exe are running in Task Manager. Oddly enough I don't remember the Catalyst being on the computer when we purchased it, nor do I remember ever installing these drivers. Uses approx 80M of RAM. Does access the internet. McAfee automatically allows this application to add itself to the Internet Applications in Personal Firewall Plus because they claim to know the application.   Henri, Montreal
Cli.exe is junk. I had 3 running in memory using about 30 MB, it slowed my graphics card frame rate down and made my CPU work too hard even with simple things. I terminated all 3 processes and my frame rate returned as well as the CPU only working at 10% while doing easy tasks instead of 60%. I have 2 GB of RAM and it still affected my PC. It doesn't matter how much RAM you have, it's buggy! You don't need the files to run unless you want the pretty catalyst control panel. You do not need this file!   JW
it has 1-3 instances running, showing from 600kt (kb) to 6mb, and the actual memory each uses varies from 8 to 30+mb, this crap can use up to 368mb RAM and bit more. close it, and sometimes it kills the comp, rebooting it, or the graphics mess up, and i suppose the card heats up alot (why the hell?) causing it to close the comp. in the worst case it destroys the graphics card, or other stuff also :S

The network connections are not trully network connections. They only listen for connections coming from localhost which happens to be your own machine. This is one method of doing interprocess communication in .net and is harmless.   jbb
To each and every ignorant person who has spoken down upon this process, this program is completely harmless, in every aspect. There is no way that this process has caused ANY of the problems that have been listed by many people. The process allows advanced configuration and control of radeon cards, which has been established many times. Each person who has claimed ill effects from this file needs to re-evaluate your PC problems, because something else is wrong. Memory Hog?

It's the ATI Catalyst Control Center. If you own an ATI Graphics Card, leave it on! If you do NOT have an ATI Graphics Card in your machine and CLI.exe is running, you may drop the process. Without it you cannot use graphics, im guessing.   Nick
I've 6-7 of them blinking (appear for a sec then gone for a sec and it keep doing this all the time my laptop is on) in my task manager and it make my laptop slow  
I have also 2 processes. I killed both of them and no problem. But I have to do that everytime I boot my laptop.   Chirag Majmundar
From ATI Catalyst Control Center - but for some reason it starts a lot (and i mean a LOT) of processes... i've once found around 100 processes started... i have 2GB of RAM Dual-Core, but my comp still runs like a snail whenever this happends. I've had this problem since last year and i found out that the only way to remove the problem is to uninstall the ATI Catalyst Pannel.   Alex
I have .net framework 1.1 and cli isnt chewing up my cpu usage, but it is causing my computer to crash. CCC has too many problems and bugs. I removed the tray icon a while ago, now all of a sudden cli keeps on screwing with my computer   Eric
i know that the 2-3 instances can actually help your system rather than hinder it, an example being, a game locked up my pc the other night, now rather than crashing the game AND my pc, the ati catlyst(CLI process) reset my video cards cpu, and allowed me to continue with my game, how is that a bad thing? its only a bad thing when you have less than 512mb ram(ati actually reccomend you have a certain amount of ram anyway), so really, ati have done the best they can, shame on you ow memory using guys for dissing them, go out and update your ram, its not hard, and is worth the benefits!   ToffeeBanana
Go into Windows Advanced Configuration Utility, Startup TAB, Click off CLISTART.EXE. It does not then start up, saves 30Mb and can be launched if you ever want it from Display Properties Catalyst TAB button. This stuff is like a virus iteself. I am on a ThinkPad T60 had no problems since.   TonyB
I have 3 of them running, using 18 MB of RAM but making the C not as fast as my  
It screwed my pc over! Had 2 cli.exe's running in my process manager each taking up 47 making my cpu usage 98 all together, and was't able to end either of them!   braed
It's just an process for the graphics of your system default and your personal graphics. That explains the 2 processes ;) If you have a third one running, it means you have the tray icon at your right of the task bar. That's it. Disable the icon if you don't want 3 processes.   Andrew
I have three cli.exe's running. They didn't start 'till I installed the ATI software. I got the software so I could rotate my screen 90 degrees. The graphics were fine without the software installed (I am not a gamer) so I am going to remove the software.   Andrew Nevelos
very annoying, i have 2 running, i don't understand how 2 files exactly the same can be running at the same time? why? if they are the same process. I also found it a nightmare trying to figure out which drivers and downloads to get when installing my Radeon 9800 pro, plus the updates and crap, they didn't make it clear what u needed.   pete
In My computer , its got three processes , each consuming 5mb each - its not that much.   thalis
Uhg...wtf, so much crap on my new laptop... this cli is a real pain, it just dosent want to die. I've done everything I can think of or find to do to keep it from loading, yet it mysteriously appears, seemingly randomly, to steal a hefty percentage of precious cpu. Damn you ati!   drumbokas
this is installed with ATI display drivers if you select the option to install catalyst control centre. If CCC is installed, remove from add/remove progs. in control panel. System runs fine without it.   Osarchos
I have 3 of them running using a total of 90mb of memory, no cpu usage though. So far I haven't had any problems whatsoever. I'm happy with these drivers, but there are other drivers you can use if you don't want ati's bloated software. Omega drivers for radeon cards perform pretty well with less ram and NO MSFRAMEWORK.   mofo

i have experience for this cli.exe in my Optiplex Gx320, everytime i restart the pc cli.exe runtime error appear, i can't find any solution for this ecxept i delete it. i go to start, search cli.exe and delete.. and it works...   elrey
CLI.exe seems to be the reason for a hang. A minute or two after startup I couldn't even start the TaskManager. But directly after startup I was able to see CLI.exe consuming more and more ram. So I stopped and renamed it. Now the machine runs without problems.   Andreas

Appeared after installing latest catalyst drivers from ATI. Looked up ATI FAQ on the matter and it claims that the program NEVER connects to "outside non-local systes". However, my ZoneAlarms has trapped cli.exe attempting to access the internet with destination IP of I therefore, do not trust this software to keep its network traffic "local".   Osvaldo Dartagnan
Part of the ATI drivers... but it can cause some problems in certain circumstances.   Endovior
Any new updated info on this? Aug 2007...   Jeff
The CLI.exe process is ofter found in multiples of 2 or 3, one for each port. The Processes are a minimal annoyance at worst but if you terminate them your games runs smoiother on older systems. If you ask me about the issue with it causing you computer to run slow. I would tell you to upgrade.   Matthew
It appeared on my task bar after installing the drivers/sw for a VisionTek X1550 AGP video graphics card (an ATI Radeon logo was on the package). All features provided via the ATI icon on the task bar are available via Display in the Control Panel. If you don't want it on your task bar, just click Start,, click Run, enter msconfig, click OK, click the Startup tab, uncheck CLIStart,, click Apply, click OK, and restart your computer.   widgit_5
ATI Control Center file. Currently causing my computer to shut down suddenly and sometimes there is no picture after reboot. Isolated the problem when cli.exe opened 72 instances of itself, using 100% cpu-processing, and displayed memory errors that could not be resolved; required hard-reboot. Researching solutions now. Running an AMD 3800+ and 3 GB RAM.   Hypatia
it uses zero percent cpu. two instances are running(not sure why). A harmless instance of the ATI Catylist Interface. Optional.   allleeexxx

ati taskbar program and uninstalling .net framework caused this error to pop up on start, so i installed it again and disabled cli.exe from msconfig to start  See also: Link   mr.info
I had more than 70 CLI.exe running in task manager and computer jammed big time, it seems every one CLI.exe used 10mb of comp's memory. It's got some bug in it!   Jaghuz
I had problems with vundo and other things, & couldn't rid myself of them, no matter what. I finally watched my Task Manager to see what was continually reloading or eating RAM. Found the CLI (3 were running). I deleted my ATI since the card I had wasn't responding to the updates I was downloading from the company. Guess what...the 100-some pop-up VIRUS warnings I was getting per day are now gone. Might not be the answer for those needing to run their graphics card, but for me, it stopped the faux warnings and the eternally grinding away of my processor.   On The Fence
my brothers girlfriend has over 100 of these running ranging from 8kb to over 10,000kb or memory...ridiculous you cannot shutdown her computer without manually powering down.   Josh
ati graphics driver component, but broken. multiple recurring instantiations.  See also: Link   Nunya Beeswax
increases cpu usage to 100%   taj
Uninstalled ATI drive, afterwards installed framework .NET 1.1 and again installed ATI drive. Now that annoying "cli.exe" error doesn't pop out anymore ^_^   dude123
Runs multiple times at once, using 6mb of memory EACH. Resource hog. Not only that, but I'm checking the file with Spybot S&D, which normally only takes a few minutes to run, & it's taken over an hour to check all the files in the ATI folder. And, no, it is not stuck or frozen; it's still actively checking the files. So far it's cleared all. Check Task Manager (Cntrl+Alt+Del) to see how much memory it uses. Too much, IMO. To stop it from running in to background, go to START-- RUN-- MSCONFIG-- (OK)-- STARTUP tab-- uncheck any programs you don't want to run.   KJM

It is part of the ATI Graphics Package. It isn't neccesary so can be removed. If you go to Add/Remove then you take it out from there. It isn't dangerous just a pain in the ass.   Luke
it will erase the magnetic strip on your credit card, deprogram all of your favourite programs out of your VCR and impregnate your girlfriend.   NFI
ATI Interface --- caught it eating 700mb of memory (twice what all other programs were running combined.)  
It shuts down my computer when its done booting.   Trancefiction
It is for the ATI driver, however the CLI.exe itself causes issues with Windows DLL operability. Solution: Stop Using ATI!! Good luck finding a Windows video card that doesn't cause Windows to crash. Although Apple uses ATI in some machines, the Unix core keeps it under control.  See also: Link   Buy-A-Mac
cli.exe - Application Error  
THIS IS HOW I RESOLVED THIS. Most likely you installed the ATI drivers but DON'T have Microsoft .NET Framework 2.0 yet. Just install .NET Framework 2.0 and your ATI Catalyst Control Center will work.   Dang
The CLI.EXE from ATI is generally NOT the problem, unless it has been overwritten by the actual virus. Look to CLI.EXE as a canary in a coal mine. In my case, after my computer got infected, CLI.EXE consumed 100% of my CPU and I had to remove it from memory to do anything at all. However, CLI.EXE was NOT the virus. Something had hijacked my atapi.sys driver and was causing this interaction with CLI.EXE. Once I (finally) removed the viruses, CLI.EXE dropped back to the 0-1% of CPU utilization it should be taking.  
If cli.exe is located in the folder C:\Windows\System32 then the security rating is 100% dangerous. ----- Scary!!!!  
hmm.i dont think its gives any problem.u'll get it after installing ATI cards..i have it only running 2 and its only around below 10k each..so it would be much problem for me since u guys are having 80+  
It load multiple times on every restart   Shmee Klass
there were 3 instances of cli.exe running...killed their processes, and nothing happened...they seem legit for ATI and the Catalyst program...If your that worried about installations and shit being left behind, install Ashampoo Uninstaller 4, Very good program for removing ALL crap from an Installation..heres the link...  See also: Link   MarkJ
I had the same problem and installing windows netframework 1.1 even resolved the issue   Uma Ganti
I installed .Net Framework 4 Before installing latest CCC and drivers... I get a message on startup that .Net Framework is not found. (I checked in Control Panel Add/Remove Programs and it is installed all right.) Same message if I just try to run Catalyst. Well, since it all can be done using Desktop right-click Properties Settings, and this program is a notorious resource hog, I just disabled it in Start Run msconfig Startup.   NotSoNewbie
appeared after installing ATI graphics card, most likely due to an error during installation as i never had .net 1.1 or higher apperently, should have done updates before installing ATI driver   Jay Bee
