Status:   Hoax.

Examples:   [Collected on the Internet, 2002]




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.

Origins:   The messages quoted above are correct in noting that Klez is a common worm which is currently spreading and infecting computers world-wide, but they contain no "immunity tools" that will protect your PC from Klez. Far from it: in classic "trojan horse" fashion, these messages (bearing a subject line of "Worm Klez.E Immunity") are disguises that trick unsuspecting users into executing their attachments — attachments which don't protect against the Klez virus but actually spread it.
