Safari keeps switching from Google to Yahoo
Please help. Safari keeps switching from Google to Yahoo
I have run Avast antivirus
Checked for unwanted extensions in preferences - there are no extensions at all
Uninstalled any App I cant recognise
Uninstalled Adobe - I think this started after I allowed an Adobe update
Google is set as default search engine
I have read every thread I can find, there are lots of references to adware removal tools but Im not sure how safe they are as they look like advertising sites
Please help, thanks
