have you looked on the actual c drive under program files for adware and have you used the search link in start menu for adware.
try that first.
if that doesnt work goto c drive and click on program files and look in common files.
if you can find it after try to uninstall it and install it fresh again. Its a good idea to downlad files onto a pen drive as this helps when when you have to install again but instaed of flaping around the net looking d=for the site you just plug in you memory stcik and downlaod from there.
I hope this helps im sure oters will have more info
