I just signed-up and if this is solved it's worth the first six month's atleast-- I'm stumped.  
This Windows 2000 PC is obviously infected with something, but what.  The latest Norton 2004 Pro identifies w32.randex.gen in svchost which it cannot repair.  When I copy the svchost file to floppy and scan it from a clean PC no virus is detected.  I downloaded the HiJackThis and here's the log file:

Hello bowinn =)

O4 - HKLM\..\Run: [Windows Video Drivers] videons32.exe
O4 - HKLM\..\Run: [Microsoft Synchronization Manager] svhost.exe
O4 - HKLM\..\RunServices: [Windows Video Drivers] videons32.exe
O4 - HKLM\..\RunServices: [Microsoft Synchronization Manager] svhost.exe
O4 - HKCU\..\Run: [Microsoft Synchronization Manager] svhost.exe
=====================================================================

fix these entries then boot into safemode and delete the files videons32.exe and svhost.exe(note its not svchost.exe) from C:\WiNNT\System32.... and run virus scan again to clean the system !!!!

thenn reboot back in Normal mode and now check for the problem ??

Well, that helped some.  NAV now does a scan, finds and removes randex.gen by successfully deleting dc93.exe.  THat's progress.  However, a subsequent scan with Spybot S&D reports "DSO Exploit" and says it's "fixing it."  I scan again and it's still there.
