Chinese anti-virus software company Kingsoft has released its "China Computer Virus Epidemic and Internet Security Report in the First Half of 2007" report.

The report says in the six months of this year, the company's anti-virus software blocked a total of 111, 474 kinds of new viruses, an increase of 23% compared with the same period of last year, and 68.71% of those were trojan horses.

The report shows that in the first half of this year, phishing-related viruses were the most dangerous virus, accounting for 76.04% of the total trojans at a total of 58,245. For example, the Worm.WhBoy virus downloads huge amounts of phishing viruses so as to steal users' online bank or game account passwords.

Anti-virus expert Dai Guangjian says that after reviewing the online security in the first six months, theft and cheating are still three main threats for Internet security and number-stealing trojans have become tools for professional virus makers to ply their craft.
