Windows Efficiency Master removal instructions
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.
