TinyWall is a very small firewall for Windows that unlike Zonealarm doesn’t bother you trying to pay for an upgrade. This firewall is free and is only 1 MB in size, and has way more options than Zonealarm ever has had. If you really want to have complete control over the network activity on your computer this is the one stop software for blocking hackers. Also it works on Windows 10
A Firewall for Windows 10!
