Rootkits find the processes that are in place to prevent illicit entry into your system. They then modify these processes to give attackers a remote pathway by which they can open a secret backdoor. Once this happens, attackers can use rootkits to secretly alter files, change processes, distribute spam, and use data mining tools to steal login IDs and passwords. Since rootkits carry out these malicious activities underground, normal antivirus software cannot locate or remove them. Even if rootkit detection were easy, once the rootkit compromised your system, ripping it out may cause you to permanently lose hidden files, network connections, blocks of memory, or registry entries.
The Tizer Secure Rootkit Razor tool can detect and effectively remove rootkits without causing any damage to your computer.
