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.

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.
   
If the file is in the startup directory it is a virus.

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.

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.

Listed in Windows Services as: Ati Hotkey Poller. No hotkeys set - can disable it.

Best practices for resolving Ati2evxx issues

A clean and tidy computer is the key requirement for avoiding problems with Ati2evxx.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem.
