McAfee Antivirus ALERT: Latest update causes file damage

Posted by Jordan Erickson

As featured on Slashdot today, the latest anti virus definition files McAfee Antivirus offers (which are automatically downloaded to your computer if the automatic update feature is enabled, which is on many default installations) contain an “anomaly”. This anomaly will apparently mark many valid program file executable and dynamic link library (DLL) files, such as Microsoft Office executables and libraries, as viruses and either quarantine them or delete them (depending on your user settings in McAfee). From the article: “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.”

Oh, my, lordie!! This is bad news for anyone using McAfee Antivirus, which is shipped and enabled by default on many new Dell (as well as other) installations.

I’m sure I sound like a broken record by now, but these news breaks about mistakes these major AV companies are making have only solidified my stance that these products are no longer a viable corporate network anti virus solution. They seem to do more harm than good! Switch to AVG Antivirus at http://www.grisoft.com. If you are an at-home user, you can get it for free at http://free.grisoft.com. As always, if you want assistance setting this product up on your company network *or* at home, give me a call and I will be glad to help.
