Unsure if infected: Zeroaccess/Gen.2

Hello,

 

Last night I got hit with a virus which downloaded an .exe onto my PC. I disconnected from the internet immediately upon finding out, and started getting repeated messages from Vista to authorize the file, which I never did. I found where it was and deleted it.

 

After that, when I reconnected to the internet I began getting messages about blocked attempts to access my computer from Trojan.Zeroaccess. They eventually stopped, but just when I was feeling safe, Norton found a Trojan.Gen.2, and wanted me to restart my computer so it could remove it. I did so, it seems okay for now, but I wanted to make sure things are alright.

 

I've been reading the other threads on this board, and was hoping I could be told how to make sure I'm fine, and what to do if I'm not.

 

Thank you.
