Poor quality product. Installation takes ages downloading new definitions. I’m unable to wait for it to complete and had to end the setup process in Task Manager. Luckily there is an uninstaller available in the program’s install dir, note: you can’t find it on Windows uninstall because it’s not yet finished installing. Using said installer could uninstall the whole thing cleanly. This is the only postive thing about this product: easy to uninstall even when installation is not really successfully completed. Other than, it’s a very bad product.
