Microsoft said that the anti-malware tool it pushes to Windows users as part of Patch Tuesday removed fake security software from nearly a million PCs during nine days this month.
In a post to the company's malware protection center blog on Wednesday, three of Microsoft's security researchers spelled out the impact this month's edition of the Malicious Software Removal Tool (MSRT) has had on phony security software. In the period from Nov. 11 to Nov. 19, said Scott Wu, Scott Molenkamp and Hamish O'Dea, MSRT purged more than 994,000 machines of what the tool recognizes as "W32/FakeSecSen," the malware label for a broad range of bogus security program with names such as "Advanced Antivirus," "Spyware Preventer," "Ultimate Antivirus 2008" and "XPert Antivirus."
