Windows Activity Booster Removal Guide

Do you know what Windows Activity Booster is?

Windows Activity Booster is a rogue anti-virus program which you should beware of if you frequently browse insecure websites, open spam email attachments, and do not avoid various advertisements. Windows Activity Booster can be installed in different ways, so if your computer is not protected by a powerful anti-spyware tool, your operating system is susceptible to various computer threats, including rogue computer security programs.

Windows Activity Booster is one of the latest programs that fall to the category of malware called Rogue.VirusDoctor. Recently, malware researchers have detected Windows Warding Module, Windows Active HotSpot, and Windows Cleaning Toolkit. All these deceitful programs have been created after a long break, and the latest discoveries imply that it is just another beginning of a new wave of scareware attack.

Even though Windows Activity Booster looks like a legitimate program, it does not provide any reliable information about the system. It only disables your computer applications so that you cannot launch a spyware removal tool and restricts your access to the Internet. These changes are made to prevent the removal of the malicious program and make you think that multiple computer infections are damaging the system. If you have Windows Activity Booster on the PC, you must have noticed a fake scanner and different pop-up warnings, which encourage you to register the application in order to have the computer infections removed:

Trojan activity detected. System integrity at risk.
Full system scan is highly recommended.

System data security is at risk!
To prevent potential PC errors, run a full system scan.

The full system scan mentioned in the warnings will not be run by Windows Active Booster even if you register it because the application is not capable of malware detection and removal. The system scans and the system malfunctions are the means of the program to push you into making the purchase of the registration key. Keep in mind that if you make the purchase, you risk losing your sensitive information, not to mention the fact that you literally throw your money away.

If you are concerned about the Trojans and other threats detected on the PC, remove Windows Activity Booster and you will no longer be provided with misleading scan results. In order to eliminate the scareware program from the PC, implement a spyware removal tool. The reason why you should rely on an anti-spyware program is that Windows Activity Booster adds its files and other components to different folders of the system, and all of them have to be deleted. If you have never tried to terminate a computer infection manually, do not try to do it in this case because the removal of a rogue anti-virus program is a very complex process.

Our team recommends that you implement SpyHunter, because this application can eliminate the malicious infection and shield the system from different computer threats. Why should you risk the performance of the system when you can rely on a professional spyware removal tool?
