Worms Are For Suckers

Wisdom from Larry Seltzer over at E-Week.
Worms Are For Suckers: "BE VERY SKEPTICAL OF ANY ATTACHMENT IN E-MAIL. This doesn't mean that you shouldn't trust any attachment at all, but unless you know the sender and were expecting the file, you should scrutinize it and not open it unless you can determine that it's legitimate.
Keep your antivirus software and firewall up to date. They aren't perfect, but they help a lot.
If your mail client can block all executables, let it. Most worms, including NetSky, will be blocked just by this. If not, find some other way to do it. It's just not worth being able to mail executables around. Incidentally, both Outlook and Outlook Express have done this for years, and therefore their users have been immune to these worms. "
