The new 8749 virus variants damage the operating system and anti-virus software.

Recently, some time ago, the 8749 virus on the user's IE homepage was tampered with to generate a new variant, variant B, with more destructive power. This not only can end anti-virus software on the user's computer, you can even delete files related to some anti-virus software. As a result, the anti-virus software is completely unavailable. Dai Guangjian, an anti-virus expert of Kingsoft drug overlord, said the virus used to delete antivirus software files is rare, and the virus is constantly improving in technology.

"In recent days, when using a computer, ie will automatically start to open a website from time to time. After the website is started, an advertisement window will pop up every one minute, it will be stopped after more than 10 pops up. In addition, when I want to search for a solution on the Internet, the browser will automatically switch to the Baidu homepage and cannot be searched properly. "Kingsoft drug Customer Service Center received a call from user Mr. Liu for help.

Dai Guangjian said that Variant B 8749 is a virus that destroys the operating system and anti-virus software. The virus destroys the security mode, closes the processes of some well-known anti-virus software, and deletes its files, so that other viruses will not be scanned and killed by the anti-virus software, and the system can be freely damaged. If a user logs on to a website of some antivirus software vendors or searches for antivirus information online, the browser will automatically go to the Baidu homepage, making it impossible for the user to seek help through the Internet.
