When doing spyware and virus scans, the following files keep coming up
as problems:

c:\windows\user32.dll
c:\windows\ntoskrnl.exe
                \system32\fccabxu.dll
                \rundll32.exe

Webpages keep loading like popups in spite of a popup blocker and
something sounds like its "running" constantly even though the
computer is idle.  I got buffer overrun msgs. until the virus/spyware
scans but I'm not getting them anymore.

The virus/spyware scans say that they are renaming/deleting/repairing
things, but they are still out there.  Can anyone tell me what to do
about this?  thanks
