please help...logs attached

I'm working on my friend's pc, who said it "crashed" when trying to set up a new desktop/"user account". Running Win XP SP2 & PC is a Dell Dimension 2400. Haven't been able to get Norton's 2003 all the way off, even using Norton's Removal Tools, & in fact, Symantec interfered with running both the GetRunKey & ShowNew scans, but I just clicked "ignore" & think they worked. Anyway, decided this PC was infected when AdAware found tons of "Criticals" & Spybot kept finding things that couldn't be fixed, even with it running on boot up with a restart. Having trouble getting online as well, & networking has been troublesome. It will not "automatically detect settings" at all & have to go in & manually enter IP address, default gateway, etc... This is the only PC we've ever had to do that with when working with this Belkin router & cable modem. System tray network icon said I was connected, but IE 7 (yuck!) wouldn't find a web page, so I changed to Mozilla Firefox as my default browser & was finally able to get online. Pretty sure that all of the scans I've ran (per sticky thread) found infected items, incl. registry keys. I've attached all my log files, as instructed in sticky thread. Can anyone help?confused Thanks! Shannon

 

Here's rest of logfiles. Thanks !

 

Ok, Tim. I did as you instructed and new logfiles are attached -- the 3 you requested. When I boot into normal mode, with normal startup checked in "run/miscofig", I get "Windows Installer" searching for a CD to install something & cannot get this window to close, either by the X or "Cancel", & have to End Task with Control/Alt/Delete. It's rather aggravating. Any ideas about what this is about? I'm assuming I need to keep the "Windows Installer" program itself. Anyway, here are my new logfiles after running Counterspy & quarantining it's findings & after fixing items you listed in HJT. Thanks! Shannon

 

Ok, thanks Tim ! Spybot has been updated to latest version. Windows Installer CleanUp Utility took care of other issues. I have set up the desktops/user acct's my friend wants. Glad log's were all clean now:cool ! All seems to be running well. Thanks so much for your time & your help!
