Worms and other malicious software that can be delivered through email will attempt to successfully exploit the recipients curiosity and then deliver their payload. And, there is no guarantee that something won't slip through your defenses. Updates to antivirus programs tend to happen only after a virus has been released and detected. You will always have the opportunity to be one of the first to catch it! The best policy is just to remove any suspicious email without opening it. If you don't know the sender, you're better off using common sense and get rid of it. Don't even look back and wonder if these messages are harmful or not. My advice is to ditch them ASAP.
Recently, I have received 2 suspicious emails. I looked in the properties of one, then deleted it as well as the second one. One title looked like porno. I heard there is a worm where the title looks like porno. Both of these passed my virus and firewall. They also passed my ISP filter, which is Barracuda. Should this have happened? If these were worms, and I deleted them do I have to worry! Is there anything I should be watching for? Thanks in advance.
