IT: Microsoft Anti-Spyware Removes Norton Anti-Virus An anonymous reader writes "According to a story over at 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. This should be a cautionary tale about deploying beta products in production environments."
