Why Firewall?

We do not want keyloggers or similar to run on our computers.

We need a firewall on all computers that is easy to use.

Instead do the driver update manually.

Run external driver update like Avast, Glary Utilities, but don’t let each program run their own driver update.

Avast Firewall

Avast provides a Firewall. It is easy to use.

But it costs 19dollar per year per computer

Feedback:
Too much Money

Avast Uninstall Painful

The Uninstall of an Avast product is very painful, in particular because they try to cross-sell a lot of different things.

I recommended to use:

1. Avast Clear – available here.
2. and/or the use of an Uninstaller software; like Revo Uninstaller
3. Step 1 is not enough, hence you might search for Avast remainders, as shown in the image.

Which Firewall to Choose?

We use TinyWall and Firewall App Fab based on the WindowsFirewall.

• Advantages of both: Small and cheap software

Disadvantage of TinyWall:

• Has problems with Sharing and Homegroup

Disadvantage of Firewall App Fab:

• Does not have auto-learn

Use Firewall App Blocker Fab when there are more computers that need a connection / homegroup.

Example : HP Elite and MediaPC in Zurich together with the two Synologies.

Use Tinywall for stand-alone computers.
