One of the main reason, I believe, why our computer is frequently infected, or reinfected, is because our computers don't wear any "condoms" when we are online. Condoms are important in preventing gonorrhea, syphillis, HIV, AIDS and other STDs from getting into our system. Virtual "condoms" are also important in preventing viruses, bacteria, rootkits, malware, hackers, hookers, and pimps from infecting our PC when we are online. Here is the "virtual condom" that I am talking about.
Most AV and firewalls allow ___-holes (borrowing President Trump's word) to connect to your network without your knowledge, but Glasswire and Comodo firewall will not. Any new connection that wants to connect to your network can only connect to your network if you "allow" it. You have the option to "allow" or "deny." When I see a new connection that wants to connect to my network, I "deny" it initially. If I deny by mistake, I can allow it the next time when it asks again for my permission. Your AV works well with Glasswire and Comodo firewalls.
But first, you must reset your PC. If you have Windows 10, you can do this step very easily. Go to All settings, Update and Security, and click Recovery. Then click Reset this PC. Turn off your router before you reset your PC. Also, make sure that you have downloaded a copy of Glasswire or Comodo firewall. During the reset phase, you want to keep your personal files. As soon as you are done with resetting your PC, install Glasswire, or Comodo firewall, and then turn your router back on.
When you see new "things" that attempt to connect to your networks, deny...deny...deny. They may be hackers, hookers, and pimps that want to gain entry into your computer's network, and mess you up. You may want to add other means of protection to protect your computer in addition to Glasswire or Comodo firewall. We wish you the best in your effort to fight hackers, hookers, and pimps.
Don't forget, remember every IP address of every device that is connected to your network, such as your computer, printer, and so forth. If you see a pop-up window with an IP address that you don't recognize that is trying to connect to your network, block that connection. See a recent connection attempt below that I blocked. I don't recognize it, so I blocked it. And my computer is still working fine after I blocked it. But if you click "I am at Home," these jerks will take over your network. Instead, click "I am at a public place." Watch for any strange behavior of your browser. Delete or uninstall temporarily your browser if you suspect that hackers, hookers, and pimps are trying to mess you up through your browser. Make sure that you reinstall a clean copy of your browser.
