Utilities? System Mechanic or Advanced SystemCare something like that
Advanced SystemCare 6.4 is a free one, but there are others.
As the toolbar is what is known "malware" something like IObit Malware Fighter could remove it
again that a freebie.
others are Avast Anti virus, Spybot Search and Destroy and loads more they are free but accept donations
of the above they are the ones I use and are fine, where to get them Filehippo, Major Geeks or
http://en.softonic.com/
If you use the download type site like Filehippo,and you see something you fancy, google it and check it out , and you go ahead don't download any extra bits and pieces, trial stuff has limited access or a time limit generally I wouldn't bother with it.
