When I try to diagnose the IE problem, it tells me that:
'Windows cannot connect to the internet using HTTP, HTTPS, or FTP. This is probably caused by firewall settings on this computer. Check the firewall settings for the HTTP port (80), HTTPS port (443) and FTP port (21).'
a) I've opened all of these ports.

c) I've run ccleaner, ad-aware, avg scan and spybot, and none of these has fixed the problem.
There is a thread here (http://forums.techguy.org/web-email/537696-http-80-https-443-ftp.html) [I haven't posted on this forum] of people who have had the same problem, and most seem to be solved via either removing Norton Antivirus (which I've never had) or removing malware. I would like to try and use hijackthis to try and remove any malware and would like some advice.
Thanks in advance for any help! Below are my Hijackthis scan log and my DDS log.
