Computer viruses and other malware are real threats. And rootkits might be the most dangerous, both in the damage they can cause and the difficulty you might have in finding and removing them.
Rootkits are a type of malware that are designed so that they can remain hidden on your computer. But while you might not notice them, they are active. Rootkits give cybercriminals the ability to remotely control your computer.
Rootkits can contain a number of tools, ranging from programs that allow hackers to steal your passwords to modules that make it easy for them to steal your credit card or online banking information. Rootkits can also give hackers the ability to subvert or disable security software and track the keys you tap on your keyword, making it easy for criminals to steal your personal information.
Because rootkits can hijack or subvert security software, they are especially hard to detect, making it likely that this type of malware could live on your computer for a long time causing significant damage. Sometimes the only way to completely eliminate a well-hidden rootkit is to erase your computer’s operating system and rebuild from scratch.
