Rootkit came to the public because it found viruses in SONY's music CD and DVD. SONY used RootKit Technology to prevent illegal copies. However, hackers quickly discovered the vulnerability and used it to hide installed files, processes, and registry information. These vulnerabilities are used to spread hidden and harmful programs, which can pose potential threats to users' computers. Therefore, Rootkit viruses are highly concealed and widely transmitted, and it is difficult to detect them by comparing traditional virus feature libraries.
So far, these viruses are not very destructive, but they are very difficult to clear. The special feature of Rootkit is that it hides its own processes, and even the registry key value cannot be hidden. The hiding here is exactly the same: the virus has two files, "*. exe" and "*. sys", which run in the memory at the same time and can be hidden and restored to each other.
The Rootkit detection of NOD32 is based on the new generation of intelligent detection technology, which is part of the NOD32 ThreatSense technology. ThreatSense technology is a very mature system based on advanced intelligent detection and unknown virus threat prevention. It can effectively detect viruses even without relying on the virus database. Therefore, the best way to prevent viruses is to enable the real-time monitoring (AMON) of NOD32 and update the virus database frequently. Enable Firewall software with excellent performance when accessing the internet. If there is no firewall software, you can use the built-in firewall software of Windows.
