I had this same issue when my machine arrived! I had Kaspersky ready to install, but wanted to Uninstall Panda first, as that would be the best choice.
It will give you an error when you try to uninstall this. What you have to do is to go the Panda website, and you basically download there Uninstaller, and then the program will Uninstall. Strange, I know, but its the only way to get rid of it!
