Windows Efficiency Master

What is Efficiency Master?

Windows Efficiency Master is a fake antivirus program, which imitates a legitimate security scanner and attempts to trick unsuspecting PC users into purchasing a 'full version'. This bogus program is created by cyber criminals who employ hacked websites and fake online security scanners to distribute their rogue antivirus program.

Commonly, Windows Efficiency Master is proliferated using a fake Microsoft Security Essentials alert message reporting non existent security threats and tricking PC users into downloading this rogue antivirus program.

Following successful infiltration, Windows, Efficiency Master modifies the registry entries of an infected operating system by disabling the Task Manager and blocking execution of installed programs.

Moreover, this fake antivirus program configures itself to start automatically on each system Startup and blocks the user's desktop. The main purpose of this rogue security scanner is to coerce PC users into purchasing 'ultimate protection' (the full version), which supposedly eliminates all 'detected' security infections.

Be aware that none of the 'detected' security threats are genuine and paying for the full version of Windows Efficiency Master is equivalent to sending your money and credit card information to cyber criminals. This program is a scam - do not buy the license.

This bogus software originates from a family of fake antivirus programs called FakeVimes. Previous variants were named Windows Safety Master and Windows Ultimate Booster. Cyber criminals responsible for releasing rogue programs from this family, do so under different names, but using identical user interfaces and functionality.

To avoid installation of these bogus antivirus programs, do not trust online security warning messages indicating 'detected' security infections and offering installation of antivirus programs. PC users should keep their operating system and installed software up-to-date and use legitimate antivirus and anti-spyware programs.

Users who observe Windows Efficiency Master scanning their computers for security infections should use this removal guide to eliminate this rogue antivirus program from their operating systems.

Summary:

The fake antivirus programs (also known as "rogue antivirus programs" or "scareware") are applications that tries to lure computer users into paying for their non-existent full versions to remove the supposedly detected security infections (although the computer is actually clean). These bogus programs are created by cyber criminals who design them to look as legitimate antivirus software. Most commonly rogue antivirus programs infiltrate user's computer using poop-up windows or alerts which appear when users surf the Internet. These deceptive messages trick users into downloading a rogue antivirus program on their computers. Other known tactics used to spread scareware include exploit kits, infected email messages, online ad networks, drive-by downloads, or even direct calls to user's offering free support.

A computer that is infected with a fake antivirus program might also have other malware installed on it as rogue antivirus programs often are bundled with Trojans and exploit kits. Noteworthy that additional malware that infiltrates user's operating system remains on victim's computer regardless of whether a payment for a non-existent full version of a fake antivirus program is made. Here are some examples of fake security warning messages that are used in fake antivirus distribution:

Computer users who are dealing with a rogue security software shouldn't buy it's full version. By paying for a license key of a fake antivirus program users would send their money and banking information to cyber criminals. Users who have already entered their credit card number (or other sensitive information) when asked by such bogus software should inform their credit card company that they have been tricked into buying a rogue security software.
