Internet Explorer connects but can’t display web page

XP Pro, SP3:
Firefox works. It is NOT a proxy setting, not what is obvious anyway.

I spent two days cleaning MAlware off machine. Also used SFC /SCANNOW.

Was using ie6, but due to it not displaying web pages, I downloaded ie7 with firefox, and installed ie7.

Still have the same problem. It does act like a proxy problem. Malare reisidual affect?

ie7 DOES display local files okay.

Is there a registry setting that could have been tampered with?
