Is Your PC Part of a Botnet?

Now there’s a free tool to find out here: mynetwatchman.com/tools/sc. It’s simple, too. Just click a link and a program begins to scan for viruses. It takes all of about five minutes.

I learned of it via anti-spam site Spamhaus.org. I also learned that my work computer is virus free—for now.
