Bedankt jtk voor je reactie en de links .
Ik heb geen idee hoe ik Safari extensies uit moet zetten .
Adware op mijn systeem acht ik klein (maar natuurlijk niet onmogelijk) daar ik eergisteren een clean-install met de meegeleverde schijfjes heb gedaan . Software downloaden doe ik normaal gesproken haast niet .
Jouw link naar Malwarebytes werkt maar vereist OS 10.7 of hoger .
Hieronder het Etrecheck rapport waarbij het woord [failled] bij 'User Launch Agents' rood is gekleurd .
En ja , heb reeds alle bits en bytes op een externe schijf staan .
EtreCheck version: 2.4.2 (142)
