Q: avast! states it has found a virus, but it only offers me the choice of: "Abort connection". Why can't I delete this virus?

A: You can't delete this virus as it's not actually on your computer. It is in fact somewhere on the net and was detected by one of the avast! resident providers - Web Shield. This provider scans all files that are downloaded via the Internet (HTTP protocol) before they're saved onto your local disk. The only action that can be taken is to abort the connection and not allow the virus to download.
