files deleted in Avast

[Teresaxhelen]

What should i do when the files that are labeled as virus, are hold in the Virus Vault?
My windows 7 system files are infected and its doing crazy things with the programs.
I tried to reinstall the files that are labeled as Infected, but i cant re-instal them anymore.
and i get this wierd codes messanges (0xc000007b) and (0xc0000005)

I reinstalled Windows 7 ,3 times now.
Simple programs like VLC, Windows Media Player and Google chrome are infected according to Avast.

Can someone please help me?

You say you have done a fresh install and avast is detecting these programs as viruses? Are both the E: Slave 20GB and the G: Slave 80GB free from viruses?
