Jon, try AdwCleaner 'free' cleaner, to remove all traces:
Please download AdwCleaner by Xplode and save to your Desktop.
Double click on AdwCleaner.exe to run the tool.
Vista/Windows 7/8 users right-click and selectRun As Administrator.
Click on the Scan button.
AdwCleaner will begin...be patient as the scan may take some time to complete.
After the scan has finished, click on the Report button...a logfile (AdwCleaner[R#].txt) will open in Notepad for review (where the largest value of # represents the most recent report).
The contents of the log file may be confusing. Unless
