You did just great!
I'm not sure if party poker was the cause, I just saw it being present with a number of these infections... I won't advice it, but there's only one way to find that out (reinstall party poker)...
The 02 entrie you mentioned belongs to Norton Antivirus. It's the toolbar that shows up in Office programs and Internet Explorer. Try to get it to work again. Re-enabling that should be via Norton main menu.
