(Recently, many users on the Internet reported that the IE homepage was changed to 123.sogou. According to the analysis of Rising Enterprise, the recently discovered problem was caused by a malicious Trojan clicker virus, which Rising Enterprise named the dog skin cream Trojan. According to Rising security experts, users will be infected with the Trojan after visiting some malicious websites, and the browser of the poisoned computer will be forcibly locked as the Sogou website. Once the computer is poisoned, the anti-virus software installed on it cannot be upgraded. If the user manually deletes the virus file netsflt.sys, it will not be able to access the Internet. At least nearly 10,000 netizens have been affected. Rising security experts show that the dog skin cream Trojan is the most destructive malicious clicker discovered in recent years. It attempts to increase website traffic by amending the browser's default home page, and then obtain commercial benefits. And the Trojan will install drivers, intercept network data, prevent the upgrade of many mainstream security software, and make it unable to use normally. The Trojan will also quietly connect to websites controlled by hackers, receive new control commands from the website, perform version updates, click advertisements, and more. The behavior of the Trojan is very similar to that of rogue software. Many netizens try to delete the virus file to solve the problem. However, after the user deletes the virus file netsflt.sys of the Goupei cream Trojan, the computer will not be able to access the Internet normally after restarting. Moreover, because common knowledge such as the network protocol stack is involved, the technical management of ordinary users is very troublesome.)
