I've received a bunch of emails recently all containing the W32.Klez.H@mm worm. All have been detected by my Norton Antivirus program. Here is information on the W32.Klez worm from the Symantec (Norton) website, including a link to a method of removing it. The site says its damage potential is relatively high and it's difficult to remove.

So......for safety, get yourself a good antivirus program (I'd recommend either Norton or McAfee, though others may have different opinions, and, most importantly KEEP IT UP TO DATE. You need to download the latest virus definitions at least every week or two. I know that's a pain in the butt if you have a slow connection, but not nearly as big a pain as getting infected.
