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). It is a type of malicious software that designed to open lots of unwanted pop ups, display annoying ads, offers and deals. Unlike viruses, the ‘ad supported’ software will not delete or infect your files, but its actions will cause some problems with your internet browser. 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. Of course, it did not ask you for permission and do it secretly as possible. Once your web-browser settings will be modified, you’ll be redirected to unwanted websites, some of which can be malicious or misleading pages. 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.
The adware that redirects your web-browsers to unwanted websites, is not a virus, but the virus behaves similarly. As a rootkit hides in the system, changes web-browser settings and blocks them from changing. Also the ad supported software can install additional browser extensions and modules that will inject ads within the Firefox, Google Chrome, Internet Explorer and Microsoft Edge’s screen. Moreover, the ad-supported software may install web-browser hijacker that once started, will change the web-browser’s start page and search provider. Even worse, the ‘ad supported’ software can be used to collect privacy data about you such as what pages you are opening, what you are looking for the Internet and so on. This confidential data, subsequently, may be sold to third parties.
Most often, the ad-supported software infects the most common web-browsers such as the Google Chrome, IE, Microsoft Edge and Firefox. But such malicious software as well may affect another internet browsers by changing its shortcuts (adding an argument like ‘http://site.address’ into Target field of a web browser’s shortcut file). So every time you launch the web browser, unwanted websites will be opening automatically. Even if you setup a new home page, an unwanted website will be the first thing you see when you start the Microsoft Edge, IE, Google Chrome and Mozilla Firefox.
