Win32/Cryptor virus

[rcfpi2]

Hello,
I have four to five viruses on my computer and cannot figure out how to get rid of them. If there is anything that anyone could help me with that would be greatly appreciated!
Thank you!

1. Please, disable System Restore and antivirus (if you have).
2. Execute this script in AVZ:

begin
SetAVZGuardStatus(True);
DeleteFileMask(GetAVZDirectory+'Quarantine', '*.*', true);
 QuarantineFile('C:\WINDOWS\system32\sdra64.exe','');
 DeleteFile('C:\WINDOWS\system32\sdra64.exe');
BC_ImportDeletedList;
ExecuteSysClean;
ExecuteRepair(1);
BC_Activate;
RebootWindows(true);
end.

3. After reboot execute this script in AVZ:

begin
 CreateQurantineArchive(GetAVZDirectory+'quarantine.zip');
end.

Upload file quarantine.zip, by link http://virusinfo.info/upload_virus.php?tid=64296

4. Make new logs.
