I am using Windows 7 with Zonealarm Free Firewall and AVG Free Antivirus 2011 and IE 8. When I started my computer I got a message from Zonealarm saying there was an update for those using the Zonealarm toolbar and AVG free antivirus. I downloaded the update but when I tried to open it I had to choose a program to open it with. Usually the updates open automatically and install. So, I deleted the update and downloaded it again but I got the same message when I tried to open it. Am I doing something wrong?
