In the Task Manager the other day, I noticed a process taking place called "Isass.exe" that I didn't recognise. I typed it into Processlibrary.com and got this:
"Process File: isass.exe Process Name: Optix.Pro virus
Description: isass.exe is registered as the Optix.Pro virus which carries in it's payload, the ability to disable firewalls and local security protections, and a backdoor capability. For More Info About isass.exe - Get WinTasks 5 Pro Now!
Recommendation: DISABLE AND REMOVE IMMEDIATELY. This process is most likely a virus or trojan. To get control over your running programs we suggest WinTasks"
Both a fully updated free version of AVG and Avast! Home edition 4.6 have failed to detect this potential virus and I can't end the process of Isass.exe in Task Manager.
