How to Protect Your Mac From ExtendedLibrary and Other Adware:

  • Get a powerful anti-malware software, capable of detecting and eliminating PUPs. Having several on-demand scanners would be a good idea too.
  • Keep your OS, browsers and security software up to date. 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 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 aps you know and trust, of course. If declining from installing unwanted programs is not possible, we advise you to cancel the installation completely.
