Here's what I have tried so far:
1. Spybot S&D scan and clean
2. AdAware scan and clean
3. 2 different antivirus programs (no infections found)
4. Re-install the ie.inf file (the sticky topic in this forum)
5. checked the hosts file in Windows\system32\drivers\etc (only the local entry, as it should be)
6. changed the registry's MTU setting to 1454 (I think that was the magic number)
7. tried Firefox (got the same results...some would load but others wouldn't)
Anybody got anything else for me to try?
T-I-A!
