Joe,I assume that I'm receiving that klez worm a couple of times a day, but Norton does't get a chance to catch it because I delete any mail with attachments from anyone I don't know, and I question large files from folks I do know who didn't tell me they were sending anything. Yesterday klez made it appear that I mailed a file to myself (the worm picked up my address in someone else's address book and put me in as sender before sending it to me).
You can visit the symantec and McAfee sites even if you aren't a subscriber to find out about viruses and hoaxes also. I use Norton Antivirus and have been updating almost daily ever since SirCam nailed my computer last year. http://www.symantec.com. They often provide free helpful files to eliminate or isolate the virus if you already have one of the particularly virulent ones that makes the rounds.
