Alarm of dangerous bot, Trojan infection rate

The latest statistics from Microsoft show that backdoor Trojans and bots are really terrible dangers for Windows users.

However, the rootkits infection rate is on the decline, partly due to updated security applications that add anti-rootkit features.

In the first 6 months of 2006, Microsoft found that more than 43,000 variants of backdoor bots and Trojans are controlling millions of computers hijacked. They form a botnet network that brings convenience to hackers.

Source: CNN Of the 4 million computers cleaned up by Microsoft's malware removal tool (MSRT), more than half contain at least one backdoor Trojan. Although this rate is quite high, Microsoft insists it has decreased compared to the second half of 2005 (68%).

Although rootkits cause a lot of scandal on the report in late 2005, this is not a big risk for users. "The number of rootkit attacks has dropped by 50%, which is a trend that needs more monitoring ," the report said.

Not surprisingly, Microsoft has identified the "chat" technique of hackers as "growing". They used a lot of familiarization, conversation, and guest tips through email and P2P networks for users.

The MSRT was first released in January 2005 and is currently being used in more than 290 million personal computers. During the first half of 2006, this tool has run more than 1.6 billion times.
