Sounds to me like you've got a bad install. With that being said, you have two options.
The first one, is to do a clean install. You mentioned that you already did one, did you use the factory disc or partition to restore? If so then that probably just restored the crapware as well. You should download an official Windows 7 ISO and install with that (using your OEM product key to activate).
The other option is to remove factory bloatware and fix your current install. Download PC Decrapifier to remove factory bloatware. Then, follow this tutorial to optimize your system.
I also recommend removing ZoneAlarm. Personally I don't see a reason to use anything more than the built-in Windows 7 firewall. For AV software, choose one of Microsoft Security Essentials, Avira AntiVir Free, or Avast! free.
Good luck :)!
