I uninstalled CA antivirus and ran ComboFix. It needed to install the Windows Recovery Console. After ComboFix rebooted the machine and reran, where it told me:
"You are infected with Rootkit.ZeroAccess! It inserted itself into the tcp/ip stack. This is a particularly difficult infection..."
Here is the log:

Can I reinstall the CA antivirus now? Or is there more to go? We haven't actually had the problem with the Internet Explorer tabs dissappearing for about a week now, but the last time we ran the antivirus it picked up more of the Win32/ZAccess.ED, so am guessing it wasn't gone at that stage (before running ComboFix at least).
Thanks again for all your help.
