Remove Windows Warning Alert POP-UP

Windows Warning Alert pop-up in your browser is caused by adware on your computer. If your computer is infected with adware, then Windows Warning Alert advertisements show up in your browser.

Not only adware is responsible for the Windows Warning Alert pop-up ads. On the Internet, ad networks can also redirect your browser to Windows Warning Alert. Some websites redirect users through ad networks to generate revenue. Therefore your browser may end up on the Windows Warning Alert site.
