One of my best mates has managed to get his desktop badly infected with malware/virus called win32backdoor.TDSS
Basically this is stopping him running any updates for or downloading any new anti virus/spyware or malware removal software.
It is that bad that it is even blocking both Firefox and IE from accessing web pages with spyware removal products or tips such as this site.
To make the problem worse then system restore isn't working so I can't go down that road.
I have managed to download Malwarebytes onto his desktop via a cd but again it won't update rendering that software useless and I can't even download hijackthis.
He is running Windows Xp Home.
I really do not know what to do apart from completely reinstalling windows and I was wondering if anybody on here had any advice?
PS. I viewed this thread earlier but the tips on it aren't any help seeing as nonne of the sfotware will download or update.http://www.bleepingcomputer.com/forums/t/198472/win32backdoortdss-reported-repeatedly-by-ad-adware-ae/
