I need some serious help!!

Hey, y'all! Been a while since I've posted here (which that's a good thing 'cause that means everything's been pretty cool with my computers! YAY! :-D ) HOWEVER, my HP mini with Windows 7 OS is infected with 17 items - 15 of which are Trojan horse Downloader.Generic11BGJT. I have no clue what these are except that they're obviously not nice. They have been moved to my virus vault (AVG). My problem is that I cannot get online with that laptop now. The other laptops and desktop get online fine. We DID install Bearshare (I know I know....don't yell at me for that! I'm married to a DJ so he needed music quick and free!) I thought that if I did a destructive recovery on it, it would take it back to just like it was when it was purchased. I can't seem to get into BIOS and I have no CD drive so I won't be able to re-install anything. Am I on the right thought pattern here or is there something else I can do to fix this myself? I'm blonde but I'm not a dumb blonde so, I think I can do it myself with the proper guidance.
So whatcha think? Any takers to help me with this issue?

 

Hello,
Did you try pressing F11 during startup to get into the recovery menu?

You can also try to do a factory restore within windows using HP Recovery Manager.
