Here you can see some tips that will help you avoid Questdns.com installation and issues with browser. Don’t hesitate to share our tips with your friends and family members as they will really help you keep your PC protected from Questdns.com and any other malicious software:

  • Don’t install software of dubious origins especially if you found them from the web pages you do not know well. People quite often commit the same mistake and get the app they need. However, eventually this downloaded program appears to be malicious.
  • Listen to your intuition! When a web page looks malicious – for example, it functions too slowly or there are too many colorful banners – we recommend you to leave it. And remember to check your PC for viruses afterwards!
  • Keep attention during the the whole process of app installation. Try not to miss a single line and a single radiobutton. Untick all boxes which are not relevant for you and you do not want to install them.
  • Even if you don’t remember downloading any software it would be reasonable to scan your system for viruses and malicious software every week.
