I'm a old user of Zonealarm. Thought I would check back to see the improvements of your software.
I developed problems with Firefox browser after upgrading to Windows 7.
I ran a full AntiVirus/Anti-Spyware scan with Zonealarm that said there weren't any problems "0." At the same time I ran a program called "Super-AntiSpyware" this program turned up 128 tracking cookies, 1 program listed as a "Potentially Unwanted Program" and 5 Addons that were causing the problems I had with Firefox.
Is it possible that I didn't have the correct settings in Zonealarm to pickup these problems or is because I am only using the free version?
I downloaded version: ZoneAlarm Free Antivirus + Firewall version: 13.0.208.000
