A huge problem has occured on Chinese computers due to an update from Symantec Corp.

It affected those who were using the Windows XP operating system. It occured about 1:00 a.m. Beijing time on Friday. The main problem was that a virus-signature update mistook two critical files in windows\system32 directory as Trojan horses. The two files that were quarantined are netapi32.dll and lsasrrv.dll.

The PCs that have been affected and rebooted will now show only a blue screen at start-up.

An hour and a half after, a new signature update was released but it was too late for those who rebooted their PCs.

A similar thing happened in March. It also involved Symantec.
