Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Combofix Log

The alerts have stopped, although I am posting from a different computer than the one in question because when I went to access both Firefox and then IE it said they were both on a registry marked for deletion and wouldn’t open.

A reboot wil clear that problem with the deletion warning

Once rebooted could you let me know what problems remain
