PCBooster Removal Guide

What is PCBooster?

PCBooster is a fake PC optimizer that tries to trick people into downloading it by pretending to be a Microsoft partner

PCBooster is a rogue computer security program, which falsely claims to be a partner of Microsoft. It promises to improve computer speed, clean it from junk files, make Windows startup faster, and extend the computer's life.

If you are an inexperienced computer user, such claims probably sound promising to you. Please, do not fall for such false statements and do not install PCBooster on your computer. It is just an annoying and fake PC optimizer, which assigns itself to startup programs and automatically runs its processes each time you turn your computer on.

PCBooster pretends to perform system scans and then displays intrusive notifications, which report that your computer is stuffed with faulty files and that there are hundreds of errors that need to be fixed immediately. However, you should not trust these claims because these “scan results” are nothing but false positives.

PCBooster removalPCBooster is a rogue computer security program that shows fake scan results.

What is more, the PCBooster virus slows down the computer's performance to make you believe that the computer is seriously messed up. However, the only aim of this tool is to frighten you and force you to buy the full version of it, which supposedly should optimize your computer and solve all the problems instantly.

Unfortunately, this application can hardly be useful in any way.

You probably already understand that the real aim of this application is to strategically create a need for its license and swindle people's money. If you do not want to lose your money, just get rid of PCBooster.

As you can see, the real problem is this tool scareware itself. We strongly recommend you to remove PCBooster with a reputable anti-malware program like SpyHunter 5Combo Cleaner or Malwarebytes. Such a malware removal tool can scan your computer system thoroughly, detect and delete all possibly dangerous programs.

Also, if you want to fix your system, it is best to do it with an official and reliable tool. We recommend using FortectIntego because you will repair all system files very easily and quickly.

Fake programs are distributed not only through software packages

This fake PC optimizer has an official website and it can be downloaded from there. This website is full of false claims about how useful this program is. However, it is not a well-known program, and obviously, computer users hardly ever download this program by their wish.

Because of this reason, this rogue application is mostly distributed via the popular bundling method, which allows binding several applications into one pack. Take note that whenever you decide to download a new program, you have to make sure that the website that suggests the download link is the official one. Otherwise, you may end up with a questionable bundled pack of programs.

Another way to reject unwanted applications is to look through the installation process carefully to notice if optional downloads will be installed alongside your preferred program. You need to choose the “custom” or “advanced” option in order to deselect the agreements to install unwanted content. It is as simple as that to ensure your system's security.

Delete PCBooster if you do not want to see fake scan results

If you have seen PCBooster's notifications about the 'errors' in your system, do not be deceived, because most of them are worthless. In addition, there's no need to buy its licensed version because it can hardly fix any computer problems.

No matter if it has appeared on your machine with or without your knowledge, you should remove PCBooster from the system without hesitation. This program will not give you any benefit and will only slow down your computer.

You can get rid of PCBooster with a help of anti-malware software. We recommend using SpyHunter 5Combo Cleaner or Malwarebytes. Also, you can try to uninstall it on your own. For that, our security experts have provided instructions for you. It only takes a few steps to delete this tool and you will find detailed explanations below.

How to prevent from getting system tools

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
