Use of two firewalls on my computer at the same time

Use of two firewalls on my computer at the same time

Like what the above post says, it is possible to install a second firewall unless 1 is only active. It creates a kind of conflict on the system when both firewalls are running at the same time. Even if you don’t install a second firewall, Windows on the other hand, already has its own firewall to protect the system. This is the basic protection of the system against unwanted or outside intrusion.

And besides, when installing an antivirus on the system, this too, includes its own firewall protection for your system. This adds strength to the firewall system of the computer which makes it less vulnerable to outside attacks. Installing Norton Internet Security on your computer also adds firewall security. It features Smart Firewall which includes different settings to detect different levels of intrusions.

Use of two firewalls on my computer at the same time

You can use two firewalls, but they would both fight to do the same work and this would cause problems. It is possible to have a software firewall and a router firewall. One firewall is all you need. They all perform the same functions in the same manner. In fact some vendors' firewall won't even allow you to install their if it detects one already on your computer. Most will automatically disable the windows firewall when you install one. The reason is that one will conflict with other and all sorts of problems can happen. So why cause conflicts when there is absolutely no reason to do so.
