Windows Efficiency Master

Windows Efficiency Master is one clandestine infection which flaunts a misguiding and fictitious interface. Cyber criminals have developed the application to trick you into thinking that malicious computer threats are flooding into your operating system. The goal for schemers is to convince you that in order to stop malware attacks and delete already existing infections you need to install a legitimate malware remover. You certainly do need to install authentic security software because a rogue anti-spyware has found its way in! Unfortunately, the rogue can activate various dysfunctions forcing you to believe that the only threat removal tool you can install is the full version of the fake AV itself. Whether you have fallen for the scam already or you are still wondering what to do, your next step should be Windows Efficiency Master removal.

Are you familiar with Windows Paramount Protection, Windows Antivirus Master, and hundreds of other Windows Efficiency Master clones? All of these rogues share the same interface, which is why virtual security experts have no issues detecting a scam right away. Unfortunately, regular computer users are not up-to-date with all of the latest security threats which is why most of them identify the rogue as a legitimate security tool. Even though the infection promises you to remove malware detected by a fictitious scanner, and uses such well-known attributes as Firewall or Automatic Updates, there is no doubt that this application could not delete one malicious component. Therefore, you need to ignore the presented scanner reports, pop-up warnings and recommendations which may flood you with misleading information. Here is an example:

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

If you click the Remove All button presented right next to this notification, you will be routed to the page assisting you with Windows Efficiency Master purchase. You are given two options: $49.95 for an unspecified term on $99.90 for the Lifetime subscription and Lifetime support. Are you surprised by such a great deal? You should because lifetime subscriptions are rare and cost much more than what the rogue offers you. This should be a warning flag signaling that maybe the allegedly beneficial malware detection and removal tool is not that great. Needless to say, the rogue is fictitious and you should not waste your money on it. So, what should you do? We advise that you remove the clandestine infection. Before you commence, you may want to apply a special activation key in order to disable the existing symptoms. The rogue can block the running of certain executables (e.g., taskmgr.exe) and slow down the machine, which may aggravate its removal.

Activation keys:
