The browser clean up tool does not nessarily prevent toolbars from being added on. Toolbars are NOT malware nor are they malicious. Your mom is actually the one who’s at fault for putting those toolbars there in the first place. Toolbars get installed by users who just click next, next and next without actually taking the time to read the installers menu. My suggestion is to better educate your mother on how to safe surf. Also educate your mother on what and what not to install. How did she get all theses toolbars? Where did they come from? Exactly what is she doing? They didn’t get there on there own.
