How Does Compatibilitychecksvc.exe Enters Your Computer?

Most PUPs enter your computer bundled with free programs you download from the Web. Bundling is a completely legal method of combining freeware with other programs in order to save on the cost of distributing that particular free program. The problem, however, is that most users are unaware that such method of distributing programs exist, mainly because it’s usually quite unclearly stated during the installation process of the freeware. As a result, most users bluntly click on “next” throughout the installation and end up with unwanted programs on their computers.

Make sure to disallow the options you don’t understand, uncheck the recommended settings and opt for custom installation. You do not need to be a computer expert to protect yourself and your system from threats from the Web.
