ATI external event utility exe module. Background task when you install ATI Display driver. It registers as the ATI hotkey poller which brings up specific ATI utilities.. Not only is this useless to 99.99% of users but there is NO DOCUMENTIATION ANYWHERE on those hotkeys. It sometimes uses up to 85% of CPU resources. Older versions of this process are known as ATIPOLAB. Thank you Perfect Process freeware for your information. Stephen4178

Difficult to switch off. I got it and I don't use ATI drivers. Uses ALOT of memory, will restart if end proccess through task manager tyler
it's used for different key combinations such as alt+F5 for switching between monitors on some laptops. Also it does when you close the lid to your laptop. Can safely be disabled using msconfig under the services tab (but the of course, the key combinations won't work). Personally I think it's a great feature and it doesn't seem to use much CPU anyway.

This service has been on my computer for sometime. It is installed with the ATI Display driver and runs the Hot Key controls so can easily do things like adjust brightness, etc. without going to the properties/settings. It provides no threat. If you don't use hot keys, simply disable it using methods described above. If you are having other trouble with your display, it is probably due to an out of date driver. ScottyDog

This is NOT a virus nor is it spyware. It's a simple program the catches hotkeys for changing brightness, etc. It should show up as a "keyboard hook" in your virus/spyware scanner. If your computer runs slow because of this process, it is because you installed the driver not correctly.
The Hotkey Poller is not needed if you are not using any of the ATI programable hotkeys...or, if your card is not designed to monitor card temperatures. Disable it in control panel/ administration tools/services Stumped2
would hang my Internet Explorer, etc. Probbaly a corrupt image, but I'm not sure. deleted it, system's back to normal.

It shows up twice on some peoples task manager because of ATI's Hydrovision (2 monitors). You can remove Hydrovision, but you will still have 1 copy of ati2evxx running in the task manager.

It is VERY IMPORTANT that readers understand that there are several ATI2EVXX.EXE files. I do not have any ATI card, no ATI card was ever installed on my computer, and this file got in my computer by some security hole. I can disable the process, and cut it off msconfig but it still manages to run again over and over. It consumes a lot of memory, and is also used as malware to modify your internet research settings (as ZoneAlarm popped to tell me lately). The best conclusion is that there is a file named ati2evxx.exe that is the harmless and not-so-useful ATI driver, and a malware. Aekar
ATI related - eliminate with msconfig to keep the resource usage as low as possible RagingBuddhist
this is a ati drive for ati videocards. if u have this in your pc and dont have an ati video card it because u're stupid enough to instali it for no reason.THIS IS NOT A VIRUS OR A SPYWARE. If your pc is runing slow its because 3d video cards use a lot of memori, and even u close the game, the memory will no be reallocated, and of course your pc will run slowly  See also: Link Master sn

This is needed for ATI Powerplay (power management). It's the service "Ati Hotkey Poller". If you disable it, the fan of your notebook probably won't stop anymore and the battery life time will be decreased. Martin
You know when you plug in an S-Video or DVI cable to your laptop and you hold Function + F5 to toggle between displays well this function is rendered useless if you turn this process off. ATI External Event Utility performs one key function it automatically detects the optimal resolution of a second display hooked into your Video Card via S-Video or DVI. This process saves valuable time as it automatically changes the screens resolution to match the max resolution of your external non primary display. So if your willing to sacrifice this process for like 200 kb of ram then do it. KSD
Initiates the restart of your computer. Communites with Ati Hotkey Poller. Don't know if this is problematic but my computer keeps on shutting down randomly (ATI card overheating?) and ati2evxx.exe is the culprit. Ben
It's a harmless (and useless) service from ATI that allows you to change video settings using HotKeys. Disable the service.... mike

well, if you have troubles with your Video Card, this nifty little thing can notify the ATI Software to restart your VPU and the OS to reboot your system if it halts... not sure it can cause system halts, but i can say this: if you have a well-maintained computer (no halts and it works fine, no parts of it have *burning* marks, no overheating etc) then you don't need it... if your video card is running suspiciosly (e.g. works under Windows excelent, but crashes withing 15 mins when you run a game) than this can be a life-saver... or the one that's causing it to reboot by notifying the OS....

This file is NOT a virus or spyware. this file is used by ATi Graphics cards on laptops (i am not sure about desktops though) this is a driver used by your ATi Card. it is usualy essential to system stability. if you do not run an ATi Card then you may want to check your system for viruses. In most cases DO NOT DELETE THIS FILE. atisux's opinion is an incorrect one this file is REQUIRED by your ATi Graphics card. Mediarocker - IT Administrator

For ATI Catalyst Control Center (CCC). Seems to control both the hotkeys and the Overdrive (automatic overclocking) feature. Disabling this disables the overdrive feature in the CCC for me. Thomas
ATI Hotkeys seem to work even when this service is not running. Oliver
ati powerplay (accessible from advanced settings of your monitor/screen) needs to have the ati hotkey poller service. If this service is not running, powerplay will be stuck to whatever condition it was running in before. Use it if you want to save laptop battery power with Powerplay.
While not dangerous in a viral sense, it did cause grief to terminal services. Setting up RDP with environment chosen to launch into an app, this exe also boots as a process for the RDP user. When the user closes the environment's launch application, RDP should disconnect them. The app ati2evxx.exe is also launched for each connection, and refuses to shut down, causing the terminal connection to stay open. SOLUTION: Disable the service ATI Hotkey Poller, and this app will not lauch, allowing RDP users to properly release their sessions when quitting their launch application. Peter Anton
Yeah I'm pretty sure I have no ATI graphics card - or any dedicated graphs at all, just intel integrated. If this is the case for you too, killing it and even deleting it won't stop anything running If anything it will free up a little chunk of mem and end some problems with games. spider
Have two of this exe run as services. and it's normal. You can disable the Windows service named Ati Hotkey Poller in the services settings. If you disable this service you will loose the ability to use the following ATI services: Hot Key Poller, VPU Recovery, Overdrive/Temp Monitor.The Overdrive tab will actually be removed from the control panel. If you disable the HotKey Poller you may also want to do the following tweak: Go to C:\Windows\System32 Locate Ati2evxx.dll and rename it to ati2evxx.dll.old. This will prevent an annoying boot lag caused by disabling the Ati2evxx.exe in services.  See also: Link Hugo

ATI Driver
It is useless on cards until x1900 series. It is used on x1900 and above to change from 2D to 3D clocks. Your card is on 2D clocks when in desktop mode but when you start a game hotkey poller changes your clocks to 3D clocks. This is used to lower the heating and PSU consuption in desktop mode. cell
This is a part of the ATI graphics card drivers, and is useful! What it does (among other things) is detects 3D applications and ramps up the core and memory clocks to handle it. Otherwise it runs in 2D mode, using less power and making less heat. If disabled it may leave your card in 2D mode, retarding performance. Phage
Its generally not a virus or malware. Used for power management with ATI Graphics cards...may sometimes cause laptops monitors to no longer respond if switched from AC power to battery power. Can be disabled in Safe Mode to keep from lockup up display. No fix found for it currently. Gyzmo
Completly uselless, can't br configured and may cause some programs to crash when they use the same hotkeys this service use. Can be deactivated as service oder completly removed in msconfig witout any problems

Can confirm, as others have stated, that this is used to poll keys for display settings and therefor is probably not needed. HOWEVER, my old desktop PC would not restart properly with it disabled -- windows shutdown fine, but i would have to reset the power supply manually to finish rebooting. Took me a long time before i realized this was caused by disabling this service. atomizer

Usually harmless, but is the source of a problem caused by an October Steam update for all Half-Life mods (CS, Sven, NS, etc.). Removing this process from the processes tab has fixed the mouse & keyboard slowdown glitch. FW
This is the hotkey listener for your ATI card (it may have other uses too), However this process sometimes causes screen flickering and system lag time, especially when using an external screen or TV. I have not yet gotten rid of the process but I've found a way around it using Omega drivers.  See also: Link Andreas
this can be for a virus or card. iv never had it before and i think i have a virus now but i installed ati drivers so think its for that

As many of the previous posts have stated, it's the ATI Hotkey driver, which lets you switch between multiple monitors by a using hotkeys (ex. CTRL+ALT+F). But it's also used to automatically detect when you connect an external monitor to your laptop! If you disable this, you won't automatically get a picture on your external monitor when connected via DVI. When I enabled it again (using Administrative Tools/Services) I immediatly got picture output (clone) on my external monitor. BadCash
It uses a name similar to that of an ATi video card driver but is not stored in the correct location. It is a trojan and it does need to be removed. Ryan Hole
ATI Hotkey poller. Installs with all Radeon drivers. Most people never notice it. However, it frequently seems to start hogging CPU on its own. The effect of this can be seen as "Jerkiness" in 3D games and videos. As a rule, I disable this in services every time I upgrade an ATI driver. I've never had a problem from disabling, but it almost always causes me issues if I don't disable it. Multiple computers (We have 4 with ATI cards, both laptops and desktops) and it has adverse effect on all of them. Blake
Additionally some of our more inquisitive users have been able to prove that ATI2EVXX can sometimes be an incredible resource hog using up to 85% of CPU utilization. PowerShot-x

I had the Ati2evxx.exe error on my Dell XPS 400, with Radeon Graphics card. I found a new video driver on the ATI website (dated 28 March 2007), downloaded it and it fixed my problem. If you have the same error upon bootup, then goto the ATI site, look for your driver, and you just might have found your fix. Brad
Two types, if run by systems, it is an ATI graphics feature. Otherwise, it is malware and should be deleted. If concerned, enable your task manager to display I/O reads, and if the number is large (10^5 or 10^6 shortly after boot), it is no good, otherwise it's the driver. Be especially aware if you do not run an ATI card, or if the process shows up twice. The designer may have named it such to mask it's identity as a data miner. May show up in startup tasks as a blank entry. If such is the case, disable immedately. thatspsychotic
Associated with ATI drivers, though non-essential. Disabling this will reduce driver-specific functionality to standard Window's configuration options. Removing this will not disable external monitor support - the user may fall back upon Window's own switching methods. Disabling this will disable dynamic performance options; game-specific quality settings will not be invoked. White Hawk
Say what you want, NO PROCESS should appear duplicated in the task manager. This is not normal, and may cause the video configuration to be unstable. ATI or not, it is useless. May not be harmful, but it surely does something WRONG. Mario
Like most have said, Spyware and most other virus/problems can disguise themselves as a harmless file. If you have more then one file with the same name in the same place, most likely is spyware or something of that nature. Chris
Ati graphics executable, not sure if its included as part of the driver or Catalyst Control Center, but it does apply to desktop PCs not just Laptops. It shouldnt be present on a system running an Nvidia card unless you have a motherboard with built in ATI graphics for example, but when than i'd recommend disabling the onboard graphics and using the seperate card. Its a safe file thats for sure. t31os

Two versions exist. One is a genuine file made by ATI and uses a hotkey function to change monitor settings. The other is a trojan that almost has the same name but uses a unicide character that looks the same but isn't. The illegitimate version resides on your computer and is activated when logged onto the internet. It turns your computer into an email server as part of the spam network. Kaspersky Anti Virus detects it and disables but does not offer a permanent solution. My particular trojan works through a Dutch server. Use DOS prompt and netstat command to find what's using connection. Robert Moore

I have dual monitors. I found that this software swaps my monitors left to right every time I log in or unlock my PC. I killed the process and that stopped happening. I don't need hotkeys to do anything with my monitors, so I wanted to prevent this process from running at startup, but I didn't see it in my list of startup apps in msconfig. Ah well. At least I know what was causing my frustrating problem. Todd

Yep, it's the ATI Hotkey Poller, and it's useless unless you want to mess with your screen using the hotkeys (I don't). But it CAN cause problems when the service is enabled because on playing video, it can reset your power options in the control panel tab. Chris

It is the ATI Catalyst Control Center and yes it is required if you want to play games and use anti-aliasing etc. It is absolutely not a trojan / worm Ceeja
Installed with ATI Catalyst Control Center (ATI Video cards) - harmless. If you think it's a virus or trojan, simply go to control panel, add/remove programs, run the ATI software uninstall utility and if it goes away it was not malware. Of course if you are using an ATI video card you will need to reinstall the drivers from ATI afterward. If you don't know how to do any of this you shouldn't be trying to troubleshoot pc's. Some of you people are simply idiots. Angus M.

Slows your PC, uses tremendous amount of I/O reads as seen in Task Manager Frederik
It is a service that can be useful. F.i. for an evening Youtube. With all these different video qualities you can use a ATI Hotkey to change contrast or saturation immediately. If you don't want it, it is not smart to remove the file. Go to Administrative tools Services (Vista), stop the Service and change Automatic to Manual. In the ATI Catalyst Control Center (Advanced view), in the Menu, select Hotkeys and uncheck 'Use hotkeys'. Now you can start and stop the service using this Control Center. Erik

There is definitely a piece of malware that uses this filename. Initial symptoms are machine running slow, failure to install some windows updates, certain mcafee services get turned off (eg spyware scanning). If you look in task manager you will see multiple instances of this file have been spawned. Try displaying the IO Writes in task mgr - this process was doing a lot of IO writes and my hard disk was chuntering. Attacked it by killing all running instances of it, disabled the service. The mal files were located in windows\system32 so I renamed them and moved them to another folder. Maple
A process that can "go wrong" thus slowing down your whole 3D performance. Ben
Nothing really but i just renamed the file with a "1" so the computer can't find it and screw me. Old School
just ATI driver(if u don't use ATI, it should be dangerous) YTK
This service is essential to ensure your display card function is running properly, it's not for hotkey ONLY, do not delete it unless you are having issues. AFAIK it is a crucial service for people that are using displayport as their monitor input since disabling this service cause me a heck of a problem with my monitor. Sieg
No need to disable this program. It is needed by the display hardware. Baneste
it's the Ati Video Driver DarkSwipe
If you're running the wrong driver for your ATI card then this program can malfunction. When it goes wrong it can take down an XP box. Liam (SiX) Deeney
This started take almost 80percent of my CPU suddenly. (May have some ralation with Open Office or Adobe Light Room) Kasun Rajapaksha
For some reason with remote desktop and local user sessions switching it periodically started increasing instances of this process. Session initialization especially for remote log in took tremendous time on my XP. Full computer restart was temporary solution. LOgon/logout/restart went veeeery slow. (tens minutes!!!) Everything is fine after I got rid of it (Hijack this - removed the entry + some unneeded service stopped). Those who have problem with long session log in/log out and remote sessions can take a look at this process. Pasha
Listed in Windows Services as: Ati Hotkey Poller. No hotkeys set - can disable it.  See also: Link Irwin Mainway
It can suddenly start using 100% of your resources. Go to services.msc and disable ATI Hotkey Poling which is not needed by most people. Paul
After doing a "save nothing" update from Vista to Windows 8 Pro, and installing the ATI CCC, Task Manager showed ati2evxx.exe using 85-99% of CPU. I disabled ati2evxx.exe and all ran as I expected, including the exclusive use of an external (2nd) monitor. Toyman
If the file is in the startup directory it is a virus. sal
ati2evxx.exe is a Windows process that works with your display adapter. Yes there are probably viruses, worms etcetera out there with the same name, but 9 times out of ten it will be part of the display adapter. DO NOT and I repeat DO NOT delete it until you consult with a computer professional, or someone who is really experienced with computers, whether it needs to be deleted or not. You never start just deleting files on your system because someone else on a forum says its a virus. Do you research on it and thoroughly investigate before taking action. Just deleting a file off your computer because someone else says it dangerous, could cause more problems on your computer, if you are not careful.
I use it all the time safely. However, the program "Stellar Phoenix Outlook Express Recovery\spoer.exe" will not run if ati2evxx.exe is active. If you want to run "Stellar Phoenix Outlook Express Recovery\spoer.exe" then cancel ati2evxx.exe's 2 tasks and then you can run "Stellar Phoenix Outlook Express Recovery\spoer.exe" to repair Outlook Express .dbx files. Then when your .dbx files are fixed you can restart your system to restart ati2evxx.exe. The support people at "Stellar Data Recovery" are not logical, they not supportive, they are not well informed and they are quite arrogant. My opinion of them is based on "working" with them for 3 days. They have a "do it our way" attitude and do not listen to logic of any sort. Booooo on Stallar Data Recovery's support services. Dan
your download has pup spyware inbedded in it ,as picked up by malawarebytes pro steve
This was deposited in my document folder where it hid and took control of my computer. I lost complete control when connected to the internet - the only activity I could see was advertisements for security software. I only realized it was the cause because in closing down to restart, this file appeared on a list of still open files. I could not get rid of it while the internet connection was on because windows will not allow programs to be trashed or deleted that are open and on restart this program automatically opened. I disconnected the internet, restarted the computer and moved the file into trash and deleted it. I did a scan ( when disconnected) and the security program I used failed to identify the cause of my problem. Andrew
