I have been going crazy on this one. I have a HP pavillion 1023c with XP Home. I was on the net and both Firefox 3.0. 5 and IE6 were surfing fine. I suddenly lost access with Firefox but could still access with IE and Outlook Express. I could still get on in windows safe mode with both but not Firefox safe mode. Then I suddenly lost access with IE as well and finally Outlook Express. I can ping the net just fine and network diagnostics says everything is fine and the connections in network connections say they are connected at 100mb. I have tried repairing the connections to no effect. I scanned with everything except combofix as I need to do a backup first. AVG disd fine a variant of Baegle worm and removed it as well as some smaller malware with spybot. Trend and symantec online scans were clean but of course now I can't even do online scans. In safe mode however I can get on. I have tried to uninstall and reinstall both the NIC and Firefox to no avail. I turned on the guest account and same same. !!! Help. I will run SFC next. PS I tried both netsh commands to reset winsocks etc and also no go. I really don't want to have to do a system recovery/reinstall as this is a book keeping computer with no good backup. PS I have the firewall disabled and can find no ther firewalls but something is blocking it! When I type a known good ip in the address bar of either browser I get nowhere yet the tool network diagnostics sasys everything is just fine and the built in internet diagnostics in IE says it can not contact http 80 https 443 or ftp 21 that the firewall is blocking it though the firewall is disabled and then replaced with PC tools firewall and that is now disabled. I finally ran Combofix and I got IE back up for about ten minutes and then it is off again. What the? Only in windows safe mode can I use both browsers no problem.
