Hello
I am running Windows 7 on an HP G62-222US laptop with the free version of Avast. I am also having this problem, after running a scan that quarantined 3 Trojan files and a reboot scan which quarantined maybe 8 to 10 other, seemingly trivial game files before I grew impatient and aborted. After extensive Google searching I determined that only the programs under "Program Files (x86)" are affected, leaving me with the ability to run Internet Explorer and by pure happenstance, Maxon Cinema4D. I have tried to run system restore but all of my restore points are gone. I would love to simply restore all of the quarantined files but I can't open Avast. This seems like the best place to post and the most relevant thread to my problem, so I hope someone will be able to help.
