AJ Mexico via SlashDot: "McAfee released an anti-virus update that contained an anomaly in the DAT file that caused many important files to be deleted from affected systems. At my company, tens of thousands of files were deleted from dozens of servers and around 2000 user machines. Affected applications included MS Office, and products from IBM (Rational), GreenHills, MS Office, Ansys, Adobe, Autocad, Hyperion, Win MPM, MS Shared, MapInfo, Macromedia, MySQL, CA, Cold Fusion, ATI, FTP Voyager, Visual Studio, PTC, ADS, FEMAP, STAT, Rational.Apparently the DAT file targeted mostly, if not exclusively, DLLs and EXE files."Times like this I'm glad to be a Mac user. You'd think McAfee would have some degree of testing for false positives. Those are very common applications (Office!?). That's just irresponsible.
