Microsoft Warns Over Mywife Worm

Microsoft has issued a public security advisory regarding the mass mailing Mywife worm that arrives as an e-mail attachment and sends itself to all contacts in a system's address book. The worm is designed to corrupt documents on the third day of each month. It also deletes files and registry keys associated with security software.

"As with all currently known variants of the Mywife malware, this variant does not make use of a security vulnerability, but is dependant on the user opening an infected file attachment. The malware also attempts to scan the network looking for systems it can connect to and infect," Microsoft warned. "Customers who believe that they are infected with the Mywife malware, or who are not sure whether they are infected, should contact their antivirus vendor."
