Meh, got it. I ran Hijackthis and this is the logfile. So far no major damage, although I cannot load security websites and forums (like this one) and not even run the mbam-setup.exe, SUPERAntiSpyware.exe and HijackThisInstaller.exe unless I change the filename. I can use explorer because I disabled a bunch of add-ons but that might not be the reason. Help please?
