I've been redirected here by Rorschach112, who helped me remove a bunch of malware from my pc.
After removal I installed AntiVir, but when I try runnig it, I get promted that this is "not an allowed Win32 Application".
I tried installing AVG and get the error: Action failed for file avgamsvr.exe: starting service....error 1053...
Windows Updates can't be installed either. The error message says something like "The integrity of the files needed for the installation couldn't be verified. Make sure the cryptographic service is runnig". (I don't get them in English, so I dont know what the exact wording in English is).
I also get a Dial-Up 623 error, but I guess this is different from the above.
Does somebody know what's wrong and what I can do?
