2 days ago my pc got infected with some worm, i suspect. It keeps switching off my norton auto protect and my windows firewall automatically and i can't even switch on my windows firewalla anymore!! It also keeps opening up my msn messenger automatically and when i log in, a message about a photo is sent automatically to everyone on my contact list. I've tried many solutions for various problems but i can't seem to get rid of this one. Worst still, weird files start to download automatically into my pc and everytime i delete it, it comes back itself whenever i connect to the internet. I've tried Vundofix, look-2-medestroy, ewido,smitfraudfix and many other possible means but i still can't seem to fix it!! It also adds this file called b.exe,303.exe,304.exe stuff in my system32 folder. PLEASE HELP
