I’ve just spent one hour of my life manually sanitising my MackBook Air: Safari went mad and kept opening unsolicited pages with ads. I discovered that it was under the control of the annoying VSearch adware.

General idea of the solution: You need to feel confident enough to fiddle with files and folders.

You need to:

  1. find a couple of files (with HTML code) and a folder on your disk.
  2. delete them (place then in the Trash).

Precise description of the solution: go to Remove unwanted adware that displays pop-up ads and graphics on your Mac.
