Say “goodbye forever” to rootkits and other threats with Avast One — at the low, low price of free.
Rootkits are designed to avoid easy detection, often by hiding inside legitimate software. The most reliable way to find them is to use expert antivirus software that specializes in sniffing them out.
In short, rootkits allow hackers to access parts of your device that they — or even you — aren’t normally allowed to reach. This gives them unfettered control over your system, which means they can basically do whatever they want.
They don’t have to be: sometimes advanced users use rootkits to exercise greater control when customizing their own machines. But if someone has installed a rootkit on your device without your knowledge, it means they can basically exert absolute control over your device… which, when used by criminals, is universally bad.
