Nothing like updating your software and having it trash important files. Apparently a version of McAfee had an anomoly in the DAT file which caused it to trash files. "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." If that isn't a jolt to the system, I don't know what is.
