Although malware is not that dangerous as ransomware, Trojan, worm or another virus, they are developed in a tricky manner as well. In order to display tens of pop-up ads or redirect people to particular third-party websites, malware is not only set to inject Host files into the operating system and web browsers, but also modify proxy server and DNS (Domain Name System) settings. As a consequence, the users of a malware infected PCs cannot access particular websites, such as IT-related forums or pages that provide malware removal tutorials. Even more, Internet connection may be absolutely lost, but this usually happens with the more serious PC infections because adware, browser hijackers or support scam malware types require Internet space to display advertisements.

If you can’t open any website on your web browser (Google Chrome, Microsoft Edge, Mozilla Firefox, Safari, etc.) and receive the window saying that “The proxy server isn’t responding” or something similar, it means that malware has left its footprint and you have to delete it as well.
