Baidu Antivirus Is First To Eliminate Malicious Virut Botnet

PRESS RELEASE

Cupertino, CA - October 22, 2013 – Baidu Antivirus today announced that it developed a new method to detect and eliminate all variants of the malicious "Virut" botnet, making it the first known antivirus program with complete built-in protection from the threat.

The Virut botnet spreads through executable file infection (via infected USB sticks and other media), and through websites that use compromised HTML to infect vulnerable browsers. Infected computers can become hosts for DDoS attacks, spam, fraud, data theft, and illicit pay-per-install activities.

Despite aggressive action in January 2013 by Polish research and development organization Naukowa i Akademicka Sieć Komputerowa (NASK), the Virut malware remains an ongoing threat. Currently, most commercially available antivirus programs do not offer complete protection from it.

"Our new solution to Virut works so well because it takes an active approach rather than a passive approach," said Baidu Antivirus team leader Zhiqiang Dong. "We find infected files in memory, unhook APIs and clear out any malicious code that's been injected. Because of our proactive approach, all 23 million Baidu Antivirus cloud engine users are completely protected from Virut," he said.

Virut has been in existence since 2006, with new variants appearing on a near-weekly basis. eWeek reported in January 2013 that Virut controlled roughly 300,000 computers. The botnet's extremely fast mutation rate and its ability to look up alternate backup hosts makes it difficult to reliably detect, and even more difficult to remove.

Baidu Antivirus is a permanently free antivirus and cloud security application that has recently been awarded VB100 certification from Virus Bulletin, and Checkmark Certification from West Coast Labs. It can be downloaded for free at: http://antivirus.baidu.com.
