They say that bad news travel fast and here’s another piece of information which is not so pleasant after all. There is a new parasite on the loose, ready to cripple your computer if you are not cautious enough. Windows Efficiency Magnifier is just another spawn in a long throng of rogue system optimization applications, which includes such pests as Windows Care Tool, Windows Defence Center, Windows Error Correction and so on. Just like its predecessors Windows Efficiency Magnifier is a part of the Fake Microsoft Security Essentials scam which means that it poses as a genuine security product in order to attain financial gain by extorting innocent computer users.

One of the features of this rogue is that Windows Efficiency Magnifier is able to enter your system without you actually knowing it. Your computer might be still working just fine, but it is possible that you have the infection file downloaded already.
