Windows Efficiency Kit

By now you should know that rogue antispyware applications cannot be trusted, but despite the fact that computer users are much better educated nowadays, they still get infected with the likes of Windows Efficiency Kit. It is not that surprising, however, because Windows Efficiency Kit looks very much like a reliable antivirus program, so a lot of users simply believe they have installed a legitimate application instead of a computer threat.

Believing in Windows Efficiency Kit leads to a whole list of problems the most obvious of which are slow computer and slow internet connection. You will also be flood with an avalanche of fake security notifications that will urge you to purchase the full version of Windows Efficiency Kit in order to protect your computer from dangerous “threats”. Let’s not forget the fake scan and its results that present you with an extensive list of Trojans, rootkits, adware programs and other supposed computer threats. A shrewd user is bound to notice that something is not right about Windows Efficiency Kit and its promises – no legitimate program tries to make you buy it so eagerly.

If you want to protect your money, your personal information and your computer system, you simply have to remove Windows Efficiency Kit as soon as possible.

... intel\intel(r) management engine components\uns\uns.exe is suspected to have infected your PC. This type of virus intercepts entered data and transmits them to a remote server.

These security alerts have nothing in common with the actual security status of your operating system, so you should ignore them and remove Windows Efficiency Kit from the computer as soon as you can.

If you are worried about the malfunctions of the system, keep in mind that they are caused by Windows Efficiency Kit. The fake anti-virus program is capable of disabling executable files and your access to the Internet just like Windows Prime Shield, Windows Prime Booster and the many other rogue computer security tools attributed to the Rogue.VirusDoctor family.
