Jiangmin, one of the largest anti-virus software providers in China, has published its annual computer virus epidemic report and top ten virus rank for 2007, which shows that the company blocked more than 363,000 kinds of new computer viruses in 2007 when an accumulative 34,414,793 computers were attacked.

Jiangmin's data shows that by December 2007, Jiangmin's Anti-virus Center had captured over 363,000 kinds of viruses, which was six times more than the previous year and made the total number of viruses at Jiangmin's KV virus storeroom total more than 800,000.

Jiangmin says that the computer viruses grew slowly in the first half of 2007, but increased dramatically in the second half of the year. The company says that of all the new viruses it blocked in the year, about two-thirds were captured in the second half of the year.

Jiangmin concludes that the computer viruses of 2007 presented several features: mobile device safety was in trouble; companies' LANs suffered the most from the ARP virus and more and more of the viruses spread via video-based files.
