“Windows Warning Alert” Scam – How Did I Start Seeing It

The main method of propagation this scamming website uses is to slither it’s web page – winserrordirect(dot)info(dot)tm on your web browser. This can occur as a result of several scenarios.

One of those is if you have visited a website of unwanted type and have clicked on a banner or different type of advertisement, which may have initiated a web browser redirect to the web page.

Another likely scenario is if you have let the “Windows Warning Alert” scam inside your computer as a result of allowing a PUP (Potentially Unwanted Program) which displays advertisements to be installed. Such software, primarily browser hijackers and adware often cause web browser redirects to unwanted websites. You may have accidentally installed a PUP by installing a free program, like a driver or your favorite media player, for example which may have had the PUP added to the installation wizard “as a free useful extra”. Usually those installation steps are difficult to discover and this is the main reason why you should always go through the Advanced or Custom installation modes of your installer, since such installation steps are often concealed there. And the reason why your PC did not flag this program as a virus is that these low-level types of threats are often skipped by conventional antivurus software.
