[Inactive] Virus setting all files to 0kb!

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.

Malwarebytes will install and update using Safe Mode with Networking.

Is Malware-bytes a good antivirus remover? I thought it was for spyware only.

Yes, it is for spyware and spyware can be worse the a virus.

Fact is both can be horrible.

Ok, I ran a scan and this is what it found. I'm now restoring again and ill post back to see if my files have been restored and virus or spyware hopefully removed.

Please post the logs as we have folks who will not open attachments. Plus they are easier to read.

The instructions said to fix what was found. Plus, by using the restore, you just re-infected your computer.
