Current Advisory

January 25, 2021 Advisory: If your status is green or yellow, Windows Live OneCare is helping to protect you from the "MyWife" family of viruses
A new mass-mailing worm has appeared that can allow an attacker to destroy files on your computer. The "MyWife" worm can arrive on your computer in the form of an attachment to an e-mail or through a file transfer, often from a known or trusted source. We want you to be confident, though, that if your Windows Live OneCare health meter is green or yellow while you are connected to the Internet, we are helping to protect you from this known virus family via our automatically updating antivirus signatures and continuous "real-time" protection. If your status is "red" (at risk), please either take the requested action or go to the Help Center. We recommend that you make sure all your computers are up to date with antivirus software such as Windows Live OneCare.

If you suspect you have been infected, we recommend you run a manual Antivirus scan as a precaution. If you would like a detailed analysis of the "MyWife" worm please visit the Microsoft Malicious Software Encyclopedia.
