I am installing a firewall on my dad's work computer. He is not behind a router or corporate firewall. I am leaning towards Avira antivir free and Comodo Internet Security without antivirus. However, I am worried about the large volume of popups that follows Comodo's installation. Is there a way to set up Comodo so it is secure but with not as many popup notifications? BTW, my computer is behind a router and I use Avira free and Threatfire running realtime, and Malwarebytes and SUPERantispyware free as on-demand scanners. I will install Malwarebytes on his computer too. Thanks.
