In response to my post about the klez virus, I received a message from "MSNGamingZone_034285". The person suggested that I down load an attached file to prevent the klez virus from entering my system. This is what the person said: Klez.E is the most common world-wide spreading worm.It's very dangerous by corrupting your files. Because of its very smart stealth and anti-anti-virus technic,most common AV software can't detect or clean it. We developed this free immunity tool to defeat the malicious virus. You only need to run this tool once,and then Klez will never come into your PC. NOTE: Because this tool acts as a fake Klez to fool the real worm,some AV monitor maybe cry when you run it. If so,Ignore the warning,and select 'continue'. If you have any question,please mail to me. I'm too wary of attachments to open it. Is it legitimate??? I e-mailed the person , but did not receive a response back. Help! BTW, I don't have the virus, but I get weird messages saying that people I don't know received an e-mail from me with the virus attached. I've been told this is harmless.

No, do not open it.

It is just a virus disquised as a klez removal tool, it is just to trick the person into opening it.
