Remove Windows Efficiency Master Virus

I was browsing the internet, then all of a sudden Windows Efficiency Master popped up on my screen and took over my computer. It won’t allow me to launch any programs so that I can neither get online, nor run my real antivirus. I tried to uninstall it from Control Panel, but this thing didn’t list in Add or Remove Programs. What should I do? How to uninstall it from my computer?

Windows Efficiency Master – Fake Antivirus Description:

Windows Efficiency Master is categorized as rogue program that can disguise itself as an anti-malware scanner, fooling unsuspecting computer users into buying this useless program. It seems such malicious anti-virus programs are renamed and repackaged every few weeks, so that it has the similar interface like the previous Windows Safety Master and Windows Ultimate Booster virus. All of these fake antivirus programs could get into a computer by clicking malicious code or unsafe advertising pop-ups, visiting pornographic website or downloading attachment from spam emails. It should be stressed that Windows Efficiency Master is not a product from Microsoft, and it doesn’t has the ability to detect or remove viruses. Once you detect it, an immediate removal is needed rather than paying the full version as required.

Rogue program is very tricky because it can pretend itself to be a genuine security tool by scanning your computer as soon as system boots up. It won’t let you stop or cancel the scan, so every time when you turn the computer on, you have to wait for several minutes until the scan is completed. It is time-consuming because Windows Efficiency Master only displays false information and will never reveal whether your computer is safe or not. Even though it detects many threats on your computer, but you have to know that all of scan results are fictitious. The main purpose of this program is to fool PC users into believing their computers have been corrupted by numerous malware infections and then convince them to buy the non-existent full version for removal of all detected security threats. Computer users should ignore the bogus scan results and take action to get rid of this scam as soon as possible.

Windows Efficiency Master is designed to cause problems on a computer rather than to fix them. It can block all the programs installed on your computer. Whenever you try to launch an executable, it pops up fake alert immediately saying that Firewall has blocked a program from accessing the Internet. It is expected to use this attack for denying you any access to important security tools, such as Task Manager, software updaters or a real anti-malware scanner. In a short word, this unwelcome program just want to mislead computer users and give them an impression that the computer has been infected with serious threats that can block everything on the computer and if you want to get the computer working regularly as usual, activating the full version is needed. Despite its looks, Windows Efficiency Master should be considered as something harmful and have to be deleted instantly.
