Legit, What Mike said: unless you have no ATI hardware, then could possibly be a virus.
Size on Windows 7 (clean install) 480,256 bytes (483,328 on disk)
Part of the AMD/ATI driver
File does not have a User Name or Description in Windos Task Manager. when attempting to open the file location, no folder opens in windows explorer. However the website Tom's Hardware reports it is a part of the ATI control panel
I cleared it once, and it came back. It makes my hard drive thrash itself to death, so whether it is or is not a virus, it is dangerous and needs to go.
Graphics software for AMD built in graphics, common in Toshiba laptops, nothing to worry about.

Part of the AMD/ATI driver
Part of the ATI External Events Client Module installed with ATI display driver...switch off ATI External Event Service to turn off functionality
software for ATI Radeon graphic adapter. ATI was acquired by AMD in 2006. If you have problems, please update your ATI driver.

It causes slow downs I have an on board ati card and disabled it in bios and conflict with my nvidea card, got rid of it once and it came back, it is protected and atrributes can't be changed in command prompt to remove it.
ATI drivers. Even nvidia GPU users with ATI chipsets on their motherboard may still have this running as a normal boot driver.
It is an important file that will cause AMD drivers to screw up if deleted, but can be infected.
I have found two C: \ Windows \ System32 \ actieclxx.exe large 443kb. C: \ Windows/System32 \ DriverStore \ cl151639.inf_061548e7 \ B149756 \ actieclxx.exe large 443kb. In 1012 kb large task management.
I found it after a general slowdown and my hard drive going flatout. It is not in my windows/system directory and I am having trouble removing it.
AMD External Events Client Module Size: 574 KB (588,288 bytes)
it's clerly a virus it crashed the game I was playing
It has no properties nor can it be located on the disc in windows 7 Enterprise Edition. Its using 00 CPU and 1,072K memory. 1 of only 2 processes that show no description or user name in Task Manager. I do have an ATI Graphics card.I'm going to keep it. After I ran a few malware scans it seems OK.
It shuts down my computer constantly when I play games, especially a game called That game only consists of moving a dot to eat other dots, this is seriously messed up. Get it out if you can, get rid of the graphics card or anything that will make it be there, unless you want your computer to shut off every 1 hour (it got worse at some point).
event viewer shows it called the windows registry to reboot the OS. Not even a prompt in the UI. This is bad and can be considered malicious.
Pretty much needed for AMD drivers
I found this along with csrss.exe in the task manager. I had gotten a RAT and I got a chat window and he said the virus was in csrss.exe.
Is part of the AMD graphics drivers. If you don't have an AMD GPU, may be dangerous.
The file is used to bring ads to the CCC front page. and is only used when you open the AMD video control pannel. Not a problem for me. I actually like seeing the game ads.
It is used if you have an AMD graphics card
