Computer is running fine. Avast regular scan is clean and other scans are also clean, but I ran pre-boot scan and a virus was detected. I could not move to chest or delete due to an error message: "compressed file is too big to process". The virus looks something like this : App Data\Roaming\AVG\Rescue\PC tuneup\ Java: Agent.AIY [EXPL]
All of those old antivirus programs I deleted a long time ago, so not sure where this is coming from.
I am using Avast Internet security 7, Dell 5030 laptop, windows 7 sp1
Thanks
