This is pure BS. One of the "features" of the KLEZ virus is the fact that it will send out email messages from the infected computer, but it will also take email addresses out of that computer's address book and place them into the "From" field. End result is you will get a message from some mail administrator telling you that your message was undeliverable because it contained a virus or had an executable attachment. In other words, you can get one of these undeliverable notifications without having the virus in your machine. I am a real fanatic when it comes to virus protection. I use McAfee Virus Scan and it has (knock on wood) kept my computer clean. I do a lot of selling on eBay, so my email address is probable spread all over hell's half acre. I receive on the average about 6 - 10 undeliverables a day that I did not originate.
