I know I'm talking to my self here but if IE8 then in the search bar to the right of the addy bar, click on the tiny down arrow showing the default search engine.At the bottom of the list select manage searches or words to that effect.
Also check in add/remove if you've got something there pertaining to my search. Sounds like a smiley crap downloaded with a freebie program. Uninstall whatever you see that seems to point to this and run Malwarebytes after. Should get rid of it.
Yep it is a remnant from Incredimail but have removed that and nothing now shows in add/remove progs. Malewarebytes/Superantispyware doesnt remove it. Have gone to 'Manage Search Providers' and there are a few listed including Bing. I can click on remove on any of them except Mystart where the remove button is not active.
Just had an idea...... think I might try and reload Incredimail then uninstall with Revo Uninstaller using the Advanced setting. Worth a try?
