I must have downloaded a logger or virus. It rendered my virus program unusable. I can't repair or reinstall the software I use avg 7 and updated this morning I tryed to uninstall and reinstall and then tried to download and reinstall I got the following error messages

CRC failed in files.dat

Installer initialization failed due to the following error:
Undefined error: Initialization of the setup data file failed.
File header hash value is not matching. File is corrupted.

I also cant use download or reinstall adaware. or any other malware or virus checker. I did manage to run a hijack this scan and here are the results
