New computer worm virus may affect documents

BEIJING: China's anti-virus authorities on Sunday warned computer users to guard against new mutation of worm virus, which could infect various documents in their system.

The virus, Worm_Piloyd.B, could infect documents like exe, html and asp and prevent the system from restoring the affected documents, according to the Tianjin-based National Computer Virus Emergency Response Centre.

The virus could force the system to download other viruses from designated websites, the centre warned.

Experts suggested computer users update their anti-virus software and use the real-time computer virus monitoring function whenever they surf the Internet, Xinhua news agency reported.
