Okay, I trust Avast first! So here is the rest of the info: Sign of “Win32:Adloader-AC [Trj]” has been found in “C:\Users\Jordan\Documents\My Virtual Machines\Windows 7 Beta\Windows 7 Beta Hard Disk.vhd” file.
I think your mom could rather be proud of you, seeking a solution for a probable flase positive.
We’d like to get the virustotal results on the file, and if indeed a fp, you should exclude it in avast, or it will be fixed with a later update of the scanner iAVS,
is the actual file named “WindowsImageBackup.vhd” ?
if so it is a saved hard disk image from a virtual pc/server environment as i outlined earlier - someone just saved the file name as that. you’ll need to download and install either virtual pc or server to open this file - available on microsoft downloads site
