can anyone help me with my computer

[yes_yes i am]

I got hacked...i think. It was from an email... one of those screensaver emails. I opened it, and whatever it didnt work. Then I try opening NBA HangTime, and it closes right when it opens. This happens with every other game and most programs on my computer


I decide to download Norton Antivirus, a trial version. Next thing i know, I cant open any files on my desktop, including my computer. I try restarting, now i cant open anything from my start menu and all the items that usually start up dont open on start up. hmmmmmm

So I restart my computer in every single safe mode there is... no help at all.


So now all i can do is surf the net... does anyone know anything i can do? except format...
