VIRUS ALERT!!!! please help for my computers sake!!!!!?

ok, on saturday, march 3rd, i was browsing the internet, i was watching a "video" and it said that it was not compatible with Windows Media Player, i should have been suspicious then, but i downloaded it anyway.

next thing i know the little bar in the lower right corner starts giving warning signals that say things like

"Sytem Alert! Malware has been detected!"

"High Risk!: Trojan Horse virus detected!"

Please, please tell me how i can get rid of this, i have tried everything, and no, i was stupid enough to not have a anti-virus program, except for Norton Antivirus, please, i need emergency help in getting rid of this!! please, i have learned my error in going to those "videos" and i need some really bad help in fixing my computer, i do not want to send it in for repairs unless i have to.

I NEED SOME HELP PLEASE!!!!!!!!!!

By the way, everytime Nortonantivirus starts, the virus shuts it down.

That sounds nasty indeed. Ok, there's a few things you can try out here :

1. Try to restore your PC to an earlier time (2nd March) using System Restore.

2. Get NOD32, install it, run your PC in Safe Mode and run an in-depth analysis from NOD32. It's the best antivirus software out there. (and get rid of that Norton crap !!).
