Help! Unknown Virus

[Boydy]

Hi all, I really hope you can help me. I came home from work 3 days ago and my PC had lots of icons I didn't add, porn sites etc, I checked if anything new had been installed but it hadn't. I asked my flat-mate if he had downloaded anything and he said he tried to download a rar album from a torrent site but when he tried to open it the computer went mad(thanks mate). I cannot acces the internet via firefox or explorer, it just says firefox/explorer has crashed and needs to close, I try to run Spybot S&D but it won't open, Norton doesn't find anything. I have HJT and spyware blaster but not sure if either can help. I've read a few posts from people with similar or the same problem and don't really want to have to reformat. I don't know what to do, I'm not great with computers, If I could just get onto the net or get Spybot to load I think I could fix it, but its as if the virus knows I'm trying to get rid of it and won't let me do anything to be able to!
Any help really would be much appreciated. I can access the web via iphone but can't on infected pc. I have Windows XP.
Thank you.

Boydy.

You should be very careful when using torrents, especially if it's music you're downloading. What's worse is that it's copyrighted and it can be infected (malware posing as audio files). Follow the directions below:

Hello Boydy,

Sorry to hear of the problem, might be best to lock your computer in future when you go out so no one can access it.

If I could just get onto the net or get Spybot to load I think I could fix it, but its as if the virus knows I'm trying to get rid of it and won't let me do anything to be able to!

I have HJT

Have you tried to run HJT and produce a log or is the infection preventing its use?

Do you have a clean PC available to post from?

Please let me know.
