An error occurring in the update of Norton's virus database on Friday has caused millions of PCs and computers to crash-a heavy blow to people's daily work and ongoing business.

Over 1000 customers had reported being affected by the incident in Guangzhou as of Friday noon. The common symptom is that the computer may suddenly encounter a blue screen and then be prompted with an error message. The same problem remains even after a reboot of the system.

A spokesman for Symantec, producer of the Norton AntiVirus software, has confirmed that this incident resulted from inappropriate handling of upgrading AntiVirus software. He promised that the company was now working hard on a possible solution.

The latest virus Norton database was upgraded on May 17. According to some PC experts, this software, after the upgrade, would regard two essential system files (netapi32.dll、lsasrv.dll) as viruses by mistake and clear them away from computers installed with Windows XP. That causes the computer to be locked up even after a reboot. Experts also confirmed that those using the simplified Chinese version of Windows XP and Norton AntiVirus will also be affected.
