Internet blocked after malware removal

Hi there,
I recently followed to the best of my ability the remove malware guide on this forum after I seemed to pick up some bad bits and pieces which were making internet explorer pop up randomly with ads and I was alerted to a heap of blocked intrusions by zone alarm..

The programs in that thread found a lit if Trojans and things so I figure I caught whatever was on the system, however now my internet won't work, I think maybe I've left a setting undone somewhere along the way??

When I open firefox I get a popup alert from zone alarm saying it is blocking an outbound connection or something.. My firewalls are all set to the highest level, am I somehow blocking myself now from using the Internet?

Can anyone help me, I have no idea wat I'm doing -oh dear- abs using the Internet on my phone to type this is a very long and tedious task.. LOL!!!
