The Simplevideodownloader.net domain is utilized by adware that pushes a pop-UP window offering a fake Adobe Flash Player update. Adware developers create seemingly helpful web tools only to invite users to install Potentially Unwanted Programs (PUPs) or promoted products and services. Adware products are often distributed by using a freeware installer as a vessel because the majority of users handle free application installers via the 'Express' or 'Typical' option. Security experts advise users, not to install software offered by the Simplevideodownloader.net pop-up because it may open the door for possibly harmful software. The Simplevideodownloader.net pop-up is generated by adware on your system, and you might want to use a trusted anti-anti-spyware solution to eliminate the threat.
