Windows Efficiency Analyzer - How to remove?


Windows Efficiency Analyzer is a fake security application which will try to make you concerned about your computer. It will pretend to search the machine for viruses and then will return completely invented results. Windows Efficiency Analyzer can hardly be found on its way to your computer because it relies on Trojans and other malware. In most cases, it comes when you are hit by unexpected online scanners that start offering to check your PC. After clicking on such ads, malware is secretly installed and set to start as soon as you reboot your computer. To get rid of Windows Efficiency Analyzer, you should run some reputable anti-spywares, like spyhunter or Malwarebytes Anti-Malware.
