How to Protect Your PC From Custom Search and Other Browser Hijackers:

  • Get a powerful anti-malware software, capable of detecting and eliminating PUPs. Having several on-demand scanners would be a good idea too.
  • Keep Windows firewall enabled or get a third-party one.
  • Keep your OS, browsers and security utilities updated. Malware creators find new browser and OS vulnerabilities to exploit all the time. Software writers, in turn, release patches and updates to get rid of the known vulnerabilities and lesser the chance of malware penetration. Antivirus program’s signature databases get updated every day and even more often to include new virus signatures.
  • Download and use uBlock Origin, Adblock, Adblock Plus or one of the similar trustworthy extensions for blocking third-party advertisements on web-sites.
  • Don’t just click on any link you see while browsing the web. That applies particularly to links in comments, on forums, or in instant messengers. Pretty often these are spam links. Sometimes they are used for increasing the traffic to websites, but often enough they will land you on pages that will try to execute a malicious code and infect your computer..
  • Don’t download software from unverified web-sites. You can easily download a trojan (malware that pretends to be a useful application); or some unwanted programs could get installed along with the app.
  • When installing freeware or shareware, be sensible and don’t rush through the process. Choose Custom or Advanced installation mode, look for checkboxes that ask for your permission to install third-party apps and uncheck them, read End User License Agreement to make sure nothing else is going to get installed. You can make exceptions for the apps you know and trust, of course. If declining from installing unwanted programs is not possible, we advise you to cancel the installation completely.

    None of this works because Custom Search has disabled the Manage Search Engine and Extension functions.
