I'm running a Compaq desktop (about five years old) and an Asus netbook (new in August), both with XP Home, both running Vipre antivirus and both had free ZA 7.0.483.000. The netbook was giving me a message on start-up about True Vector not loading so I thought I would see if there was a newer version of ZA. I installed 9.1.007.002 and that seems to work fine. Then I decided to upgrade the desktop as well. That was the start of major trouble. It never completely installed; when I restarted I never got the splash screen I had on the netbook and every time I tried to open ZA it froze. And everything froze. I couldn't open any browser or Add/Remove programs. With difficulty I did a restore to earlier in the day and it rolled back to the old version of ZA. Even that wasn't good. I could open ZA but just got a blank screen when I did. So I uninstalled it and reinstalled 7.0 from a download folder and everything is working now.
I have two questions: First, why is ZA 9.1 working on the netbook and didn't on the desktop? And should I try it again? Second, I'm about to get a new Dell desktop with Windows 7 Home Premium and I'm not sure what to install on it as a firewall. I've used free ZA for years on various computers. Any advice on either issue? It will be much appreciated.
