"The gent who fixed it said when he re started it that i should not have Zone Alarm Pro and e Trust Antivirus on together and i should uninstall one"
Which was a load of cobblers.
Zone Alarm (firewall) and e-Trust anti-virus perform two completely different functions and the fact that they may be from the same company (I don't know, I don't use them) is utterly irrelevant.
Stick with what you have (Zone Alarm, Pest Patrol and Defender).
However, you MUST have an anti-virus program.
I'm not convinced that by doing a System Restore will have completely restored e-Trust AV after uninstalling it.
If you have the original installation CD, do a complete re-install.
If not, download click here or click here both of which are excellent free AV programs and are all you'll ever need.
