The adware that redirects your web-browsers to unwanted websites, is not a virus, but the virus behaves similarly. For this reason, we recommend that you begin the clean up of your personal computer as quickly as possible and thereby stop unwanted websites from opening automatically in your browser. Once your web-browser settings will be modified, you’ll be redirected to unwanted websites, some of which can be malicious or misleading pages. Of course, it did not ask you for permission and do it secretly as possible. This is because, it’ll hijack your system, get full access to your browsers such as Firefox, MS Edge, Internet Explorer and Google Chrome and can change their settings. Unlike viruses, the ‘ad supported’ software will not delete or infect your files, but its actions will cause some problems with your internet browser. It is a type of malicious software that designed to open lots of unwanted pop ups, display annoying ads, offers and deals. If lots of unwanted websites popping up in your internet browser then most probably that your PC is affected by an adware (also known as ‘ad-supported’ software).
