Doing a View Source shows an additional link to their site but it is hidden. Dodgy enough.
Going to their site....
"We honor all uninstall requests and do not use deceptive or sneaky tactics to keep our software on a users computer. We make sure that we monetize each users installation to the maximum without infringing on the users privacy. We vow that our program will never "clog up or slow down" a users computer, and that all ads will be completely random, with no relevancy checks."
They are using themes as a vehicle for their adware junk AND adding links which can only be for PR purposes.
Their contact form is not there. Surprise eh?
