Privacy Cleaner component

I would like notify the developers of the System Cleaner of a feature in the privacy cleaner process that does not do a complete job of deleting search criteria in Internet Explorer 7.
When IE7 is initially installed, there is a request to define the default search engine to be used.
I chose Google, so after the installation, it placed a Google search bar just across from the address bar.
When I run Privacy cleaner using the latest version of System Cleaner, it does not delete search words that were used in that field. ‘Autocomplete’ is supposed to delete the search keywords, but it does not. I used a competing product…sshhh (ccleaner)…and it was able to delete all search keywords.
Just thought I should make the developers aware of a potential privacy issue.
