According to Washingtonpost.com, the latest definitions file for Microsoft’s Anti-Spyware beta flags Symantec’s Norton Antivirus products as a password-stealing trojan and prompts users to delete portions of the program. Users who follow the instructions hose their installation of Norton, requiring delicate Windows registry edits and a complete removal/reinstall of Norton.
Microsoft’s support forum is quickly filling up with complaints about this problem, many from businesses that have been pretty hard hit.
