I have removed Snap-Do twice for a customer. When he goes on line for about an hour, Snap-Do takes over as his startup page in IE, Firefox, and Chrome.
After manually removing Snap-Do from all 3 browsers, I ran Superantispyware, which did not find it. I did not try Malwarebytes, because it generally does not find this kind of trashware.
What can I do - or tell this customer - to prevent Snap-Do from coming back after I remove it a third time?
