I have a virus...what now?

[Sundevils21]

(I am computer retarded)
So searched twoplustwo to see what free virus scanning was out there and "AVG" was recommended(somebody posted a link and I downloaded).

A search brought up this...
Virus identified- "Java/ByteVerify"
There were 12 infected files found.
2 of which I was able to "move to vault" but the others it says, "infected, embedded Archiv"
So I go the the "virus vault" and there are a couple files that are stored there, but what do I do about the others?
Any help would be GREATLY appreciated.
