ComodoPC would be similar to the freeware CCleaner http://www.ccleaner.com/ but would have the ability to automatically clean when a browser is closed.
In it’s options, the user should be able to protect selected cookied, and also allow the user to select certain folders to clean.
Hell man, I’d be happy if you added a setting/function to CPF that would automatically run CCleaner on browser exit! Maybe you can develope an affiliation with the CCleaner author!
