you're in a two-pronged area:
1 - removing what's on the computer now
I'd also suggest you run your ZA scans in Safe Mode and since your're infected the sooner the better.
Zone Alarm or any other firewall is only as good as its settings.
2 - prevention and like previous posters have said strengthen your brower by blocking everything and then if you need ebay etc allow site by site, but previously you gave permission to everybody by all the green checks in your first post.
That's how you got all the infections.
If you block 3rd party cookies at the browser level and turn on privacy advisor it'll tell you what's needed if the page does not load correctly.
you don't have to give everybody cookies just because they ask.
You can block everything on most sites and surf safely.
Again sites like ebay have to be fine tuned in program control-->site list
Bad sites are another issue:
siteadvisor.com allows you to check sites and or download their free version or paid version.
on this forum you'll find Force Field a beta product in testing.
