Got infected with Certified toolbar!!!!
Functioning perfect, suddenly Firefox 18 crushed. At restarting everything was deleted, as options, frequently opened webs, etc. And appears as starting page the famous certified search toolbar. I have scanned with <Malwarebytes unsuccessfully; also with Avast. Instrution to remove manually in Google are too unfriendly for me. I am an acqainted user but this is too much. Many thans and regards
