After reading about strenghts and weaknesses and reading reviews, I decided to try a couple of 3rd party firewall apps to replace the Win 7 firewall. I download Comodo Security Suite free edition and PC Tools Firewall Plusfree edition. I chose these 2 because of various reviews. I could have tried a couple of others, but decided these were representative of the large group of 3rd party firewalls presently available.
It seemed that after installing the above apps (they were installed and tested one at a time, remember 2 different Security Apps of the same type should not be run at the same time in real time), I started having problems with some of the other apps on my PC. Both replaced and disabled the Win 7 firewall by default. PC Tools Firewall Plus is just a firewall, Whereas the Comodo product is a suite, although you can install any or all of 3 different apps. If the entire suite is installed, it intergrates nicely with all 3 apps working together.
I started to immediately have problems with my Filehippo Update Checker. This is an app I use a lot along with Secunia PSI to update the various apps on my PC.SIWfree edition also started having problems updating.
Long story short, I uninstalled both. Let me state I’m glad I created an Up To Date Image just prior to this test. Because of the various problems I was having, I finally restored from my Image to quickly get back to where I was. This is another time when Imaging saved my bacon.
Bottom line is that the Win 7 firewall is a very good app that integrates with the OS well and just works unobtrusively in the background. As I have said, I like to try different things with my PC and this was just another example of my “playing” with my PC.
