I`m afraid that after you try ca internet suite, and if you decide it`s not for you, you will be coming back here asking how to remove it so as you can install other antivir programs, because evidently it is a bear to remove, similar to Norton, and if you do not remove it completely, you will not be able to install other antivirus software, because it will detect ca internet suite, and will not install. That said, good luck.
