We've a nasty virus at my job. At one of the networks we have at the offices, there is this thing that changes the name of it's own files and only gets to the shared folders. And, everytime we need to acces that folder, the antivirus start scanning the file and crashes the PC.
We've used Combofix once and we got rid of it in first instance, but then again it infected our network again.
The antivirus says:
AUTOIT script >> script.au3 Win32/Packed.AutoIt.Gen
