Bottom line, be sure you have only this software for your firewall, spyware and virus applications only!! As for it's protection and detection capabilities, I give it 10 out of 10!! Overall, it is worth a trial period to see if it works well with your system. If so, go with it!! https://www.gnu.org/licenses/lgpl-3.0.html
