In the second month of a campaign against fake security software, Microsoft Corp.
has booted the rogue application "Antivirus 2009" from almost 400,000 PCs, the company recently claimed.
December's version of the Malicious Software Removal Tool (MSRT), a free utility that Microsoft pushes to Windows users as part of Patch Tuesday, targeted one of the most popular phony security app, Antivirus 2009. According to Microsoft, the MSRT erased the fake from over 394,000 PCs in the first nine days after it released this month's edition on Dec. 9.
Last month, Microsoft trumpeted a similar cleaning operation against another family of bogus security software that it said had purged nearly a million machines of programs such as those called "Advanced Antivirus,"
"Ultimate Antivirus 2008" and "XPert Antivirus."
