I have a huge virus problem on my hands guys. Some virus is setting ALL of my files to 0 kb to make it look like my hard disk is empty. I've tried to roll back to a system restore which does work, but the virus seems to start when windows starts up so it started to do the same thing after the system restore.

I have restores left and I'm now in safe mode running scans with avast . I'm not sure if I will find anything because the virus isn't loaded when running safe mode. I need some help badly, is there someway I can try to catch it before windows starts? I've already tried a scheduled boot-time scan with avast and no luck.
