Today, we’ll give you a full picture of rootkit – the definition of rootkit, the types of rootkits, signs of rootkit, how to avoid rootkits and how to get rid of rootkit Windows 10.

What Is Rootkit?

what is rootkit

A rootkit is malicious software which allows malware authors to hide worms, bots and malware without your knowledge as long as possible. It is pretty difficult to detect because it can conceal its existence in an infected system. What’s more, rootkit is able to steal your data and resources to keep a lookout over your communications and privacy by noting down your keylogger method. If you probe this article under our explanation and guidance, all your trouble can be easily solved.

Types of Rootkits

Rootkit boasts of a number of varieties. In this section, we will introduce you to several typical types.

Type 1. Application Rootkits

Application Rootkits also called User-mode, are the easiest and the most detectable ones because they perform their vicious actions by hiding in the application itself rather than in crucial system files. They run in the same part of infected applications.

Type 2. Memory Rootkits

As the name suggests, Memory Rootkit can hide in the RAM of your computer and take up all the resources of involving malicious processes hence harming your RAM performance.

Type 3. Bootloader Rootkits

Bootloader Rootkits or Bootkits start at the same time as your OS. They attached themselves to MBR (the master boot record) or VBR (the volume boot record), so you cannot see them in the standard file-system view. Naturally, it is hard for antivirus software to find them.

What’s worse, Bootloader Rootkits have the ability to tweak the boot record. Once your device is infected by this type of rootkit, you cannot delete it because the deletion will damage your computer due to a changed boot record.

Type 4. Hardware Rootkits

This type of rootkits are based on some software that run hardware components. They can waylay any data written on the disk by burying themselves on the hard drive.

According to the latest report, Hardware Rootkits are likely to hide themselves deep into the UEFI hardware of a PC. In other words, they are so damaging that you must get rid of them.

Type 5. Kernel-mode Rootkits

Kernel-mode Rootkits are less common but they are so destructive that hackers can control your device completely once infected. Kernel-mode Rootkits allow hackers to own the most powerful privileges of your computer thus they will have heavy impacts on your computer operating system.

Type 6. Hypervisor-based Rootkits

Hypervisor-based Rootkits are more destructive than Kernel-mode Rootkits. They will create a virtualized rootkit machine which will boot up earlier than your OS. Obviously, Hypervisor-based Rootkits master more control than Kernel-mode Rootkits and they are even harder to remove.

Signs of Rootkit

Rootkit is hard to detect but it is not groundless. Since it can harm your computer, you must perceive some signs of it before you are bothered by how to get rid of rootkit Windows 10.

Sign 1: Weird Performance of System

Rootkits enable malicious attackers to control your operating system. If your computer acts weirdly, the culprit might be hackers beyond rootkits.

Sign 2: Unexpected Changes in Settings

Generally speaking, your computer cannot do anything without your knowledge unless infected by rootkits. If you discover that your settings and configurations are changing automatically, your computer is likely to be manipulated by others.    

Sign 3: Unstable Network Activities

If your device is running slow at times and the antivirus software is unable to detect any suspicious process, you need to pay attention to that because hackers are inclined to receive traffic and data from your device, which interfere with the network connection.  

Sign 4: Existence of Rootkits Signature

The computer operates with numbers called signature and those numbers help the operating system to identify different data storage devices on your computer. Therefore, as soon as rootkits exist in your computer, there must be a corresponding signature of them and you can be aware of how to detect rootkits on Windows 10. 

How to Avoid Rootkits?

There are several ways about how to prevent rootkits. Here’s how to do it:

Plan A: Download Software on the Official Website

Rootkits may bundle with some applications if you download them from unofficial locations. Therefore, you should make sure a reliable source of the rootkit.

Plan B: Be Wary of Phishing Attacks

Don’t open any links or attachments from strange or unknown individuals or organizers and don’t trust any mails showing that you win a lottery. Those mails alike are likely to be phishing attacks. Once you open them, you will download some uncontrolled and executable programs thus giving the chance for the rootkit to slip on your computer.

Plan C: Update Your Software

Keep all your software and system up to date lest hackers take advantage of bugs and vulnerabilities of the obsolete version. Ordinarily, companies will release corresponding updates to fix previous bugs regularly. As long as you update in time, the rootkit cannot sneak into your system.

Plan D: Monitor Network Flow

Rootkit Attackers have the ability to receive your network traffic and data hence there must be some changes in your network flow. Network monitoring can recognize potentially abnormal network flow and mitigate threats more quickly.
