McAfee sent the McAfee 5958 dat update for its users. Unfortunately, the McAfee 5958 dat has been identifying a normal Windows file as a virus. It seems to affect Windows XP SP3.
McAfee Inc. confirmed that a 5958 software update (not “Error code of 5958?) it posted at 9 a.m. Eastern time caused its antivirus program for corporate customers to misidentify a harmless file. It has posted a replacement update for download.
