10 most dangerous malicious codes in March 2007

British security firm Sophos has announced the list of 10 most dangerous malicious codes in March 2007. Accordingly, the leading position belongs to a very old name - Netsky.

After losing the leading position to a very new name HckPk - a newly discovered and extremely dangerous line of malicious code - this month Netsky has "easily" regained what it lost.

" The email that contains Netsky is still very much on the Internet. It proves the danger of this malicious code as well as the danger of spreading malicious code by sending a large number of emails ," Carole Theriault - Sophos senior security consultant - said.

" The more dangerous the Internet is the existence of a lot of new malicious code. But the users are still unable to protect themselves against a malicious code discovered three years ago. Love. The more complex the image becomes, the more people are connected to the Internet . '

Although it was discovered three years ago and now security products can be destroyed, Netsky still spreads widely. Statistics of Sophos show that in the past month, this malicious code accounted for 32.7% of the total number of virus notifications sent to the company in the past month.

March also saw the rise of another very familiar "name" Mytob. This virus is not inferior to Netsky when it accounts for 30.4% of all messages sent to Sophos.

According to Sophos, the rate of virus infected emails in March continued to decline very sharply. Currently only 1 out of 555 emails sent is viral - equivalent to 0.18%. March Sophos discovered an additional 8,835 new malware. This figure shows that email sent via email is still a problem without a thorough solution.
