Windows Activity Booster

Windows Activity Booster is the newest addition to the Rogue.VirusDoctor family, and our researchers have discovered that the interface of this threat is in no way different than the last fake AV, known as the Windows Warding Module. In fact, this is no surprise as tens of different infections from this faction, including Windows Active HotSpot and Windows Cleaning Toolkit, use the exact same interface. Even though this allows people who have already dealt with one rogue from the family to recognize a threat instantaneously, there still are hundreds of thousands of Windows users who could end up having their systems infected. Do you know how the malicious fake AV can enter your personal computer? As our researchers indicate it is usually distributed through fake online scanners which falsely warn that you need to delete malware which has corrupted the system. There is no doubt that you need to remove Windows Activity Booster because it is the main infection.

Whether you consented the installation of Windows Activity Booster after clicking the downloaded button presented via the fake online scanner or the infection has been dropped onto the computer without your knowledge you are bound to face the same symptoms. As research has revealed, the clandestine rogues from the VirusDoctor faction can block most executable files making it extremely difficult to delete Windows Activity Booster from the PC. Since you will not be able to access Task Manager and Registry Editor you will face serious manual removal obstacles. Restricted access to the Internet connection will also create problems installing automatic malware removal software. Due to these issues you may start thinking that the only way out is by paying for the full edition version. If you do not want to waste money on a program which cannot detect/delete malware you should ignore such recommendations:

Activate Windows Activity Booster to get ultimate protection against Identity Theft, Viruses, Malware and other threats!

Please click “Remove all” button to erase all infected files and protect your PC

Unfortunately, Windows Activity Booster removal is not the easiest task you will face. The clandestine infection can paralyze the system and make it impossible to do anything else but pay attention to the truly intimidating computer scanner, pop-up warnings and full-version purchase recommendations. These are fake and you should not think you need to delete allegedly attacking threats. In fact, all you need to do right now is remove Windows Activity Booster and there is no doubt that automatic malware detection and removal software is your best choice in this case. We have prepared the instructions which will help you install a reliable security tool onto the PC and delete the rogue.
