Apologies if I am not using the forum correctly as this is the first time I have ever used one.

I have been running ZoneAlarm V7 for some time now with no problems but after upgrading to V8 the pc became unusable. The pc took 20min+ to boot up and as for trying to run any program... well a ZX81 was quicker.
I had installed Microsoft Service Pack 3 at the same time and thought that might have been the problem so I uninstalled it but the problem still persisted. I then uninstalled/re-installed V8 but no change, I uninstalled again I tried for a clean install rather than an upgrade but I was not given the option to do so again. I have had to revert back to V7, any advice please (I have found it very difficult to report the problem to Zonelabs online)

Operating System:Windows XP Home Edition
Software Version:8.0
