OK I tried Malwarebytes, and it's working pretty fine. It flushed out the viruses, but it can't seem to do away with the autorun files, so the copies are being made as soon as they're deleted.
Then since I lack safe mode I decided to try it in the diagnostic mode from msconfig after disabling all of the non critical services and programs (read elsewhere that it might help), but again, it made no difference.

I can't seem to access the website at all...

I'm really running out of options.
