Flawed Symantec Update Cripples PCs
According to the Chinese Internet Security Response Team, an antivirus signature update from Symantec mistakenly quarantined two critical system files in the Chinese version of Windows XP crippling computers across the country. Oops.
Norton Antivirus, Norton Internet Security 2007 and Norton 360 users who installed an antivirus signature update released by Symantec on May 17 could not reboot their PCs. The update reportedly mistook two Windows system files--"netapi32.dll" and "lsasrv.dll"--as the Backdoor.Haxdoo Trojan horse. The two files were subsequently quarantined.
