Chuck, I think you have a problem. It seems to be a hard to cleanup type of problem. I did a Google search and didn't find anything from a recognized virus/trojan prevention site on how to remove it. I did find forums that had links to sites that claim to remove the toolbar. Reading further down the page there were warnings not to visit the sites referred to.
You might have some luck going to sites like Mcafee, AVG, Avast, Malwarebytes, Emsisoft, etc., etc. to see if they have any info on this particular malware.
Best of luck and let us know how it turns out.
Sorry I couldn't be more help.
Jim
Chuck, I did some checking. Malwarebytes has some information on your problem as does Norton (Symantec). At MB I did a search for Snap.do and found someone had removed it using their instructions. At Norton I did a search in Support.
Note that both sites say "Don't follow these instructions yourself, they are only for the person who requested help". I take that to mean that you should open your own support request in the site so they can tailor the instructions to your problem.
Jim
