Wincheck is an adware helper that is installed alongside unreliable advertisement-supported programs. Needless to say, we strongly recommend removing this software from your personal computer, because it could open up security backdoors and jeopardize your own virtual security. In most cases, adware helpers are deleted together with adware, but it is possible that you will have to remove Wincheck from your operating system manually. This report was created to help you bypass all removal obstacles.

You must beware of the updates as well, because malicious files could be dropped on your PC to perform malicious activity. Keep in mind that other adware helpers could have been installed as well, and it is just as important to delete them as it is to delete Wincheck. You can detect these threats – if they exist – using an automatic malware scanner.

The adware helper that you need to delete from your operating system is usually located in the Wincheck folder found under %LOCALAPPDATA%.
