AVG Antivirus Update Paralyzes PCs

For those using AVG antivirus software localized for certain European languages, you probably had some extra work this week.

A signature update on Saturday, November 8th mistakenly identified the Windows system file "user32.dll" as a trojan horse program. The AVG software quarantined the file and then deleted it. If you restarted your PC, it would display a blue screen error message indicating that Winsvr could not be found.

AVG quickly corrected the signature file and distributed it to all users.

This is not the first time AVG has had this type of problem. Let's hope they review their updates more carefully going forward. Or you could always choose not to use AVG.
