IT admins across the globe are letting out a collective groan after servers and PCs running McAfee VirusScan attacked core system files, in some cases causing the machines to display the dreaded blue screen of death.
Details are still coming in, but forums here and here show that it's affecting McAfee customers in Germany, Italy, and elsewhere. A UK-based Reg reader, who asked to remain anonymous because he was not authorized by his employer to speak to the press, said the glitch simultaneously leveled half of a customer's 140 machines after they updated the latest virus signature file.
"Literally half of the machines were down with this McAfee anti-virus message IDing valid programs as having this trojan," the IT consultant said. "Literally half the office switched off their PCs and were just twiddling their thumbs."
When the consultant returned to his office he was relieved that his own laptop, which also uses VirusScan, was working normally. Then, suddenly, when it installed the latest McAfee DAT file, his computer was also smitten. The anti-virus program identified winvnc.exe and several other legitimate files as malware and attempted to quarantine them. With several core system files out of commission, the machine was rendered an expensive paperweight.
A McAfee representative in the US didn't immediately respond to phone calls seeking comment. Friday is a holiday for many US employees in observance of Saturday's Independence Day.
