[Terje]

Hi.

Infection date and initial symptoms:

01.06.2017
Current issues and symptoms:

Tabs with ads opens in all browsers when clicking link or manually enter adress
Steps taken in order to remove the infection:
Run Malvarebytes Anti Malvare, reset all browser settings, reset homepage in all browsers, checked for unknow programs and deleted those, run all maintenance tools for osx, gone through all extensions in all browsers.

I would like to know if you guys have another solution than the ones I listed.

Thanks.
