PC has: Windows XP Home SP1, IE 6, AOL 9.0 SE
Unable to view any https://
pages in IE or AOL. Can view http://
fine in IE or AOL.
Unable to run any Active X controls - settings are all default under Internet Options. Have also tried setting Internet Zone to low and also manually setting Active X to enabled. Uninstalled Flash
Uninstalled expired Norton AV 2004. Wanted to clean up using Norton Uninstall tool. Unable to run Norton Uninstall tool - error msg: "SymNRT: Invalid Signature. This file is unsigned so it won't run"
Removed several viruses (trojans) with current AVG and a lot of spyware (180Solutions, Gator, ISTbar, etc.) with current SpyBot.
Cannot install Windows XP Service Pack 2 - it unpacks everything, then ends with a pop-up that says "Setup Error: The system cannot find the file specified."
Cannot run SFC /scannow - After about 1 minute of no progress, the Windows File Checker window simply closes with no error message.
Cannot run WIndows Update or Online scans due to Active X failure.
I think one of the viruses altered the registry or the TCP/IP stack or Internet settings, but I can't figure out how to correct it. Any help would be appreciated.
