unknown process running and sometimes an error on restart

I have an unknown process running,"comvga.exe."on my DELL PC with XP OS. When I try to end process it starts back up immediately. It is
not listed under start up programs under msconfig. My
system seems much slower since I noticed this process
running. Sometimes, when I restart I get an error that
says "Windows\windows update setup files/ mfcnut.exe" or
sometimes it ends in "webjpeg.exe" and then says "****
happens while copying to" and has the OK box to click or
you can x out in the corner box. With an error message
like that it seems like a virus maybe. I have ran my
virus scan (current updates) and also have Adware and
Spybot (current updates) and nothing has found it. I
also searched on the Internet and could find nothing
about it. One other note, I had something named REGSVR32
(all capital letters if that even matters) load onto my
Computer somehow one day when I was on line. It just
came up and said download complete when I never initiated
any download. I already had this on my Computer but the
name in small letters (again, don't know if that matters
or not). I don't know if these are related or what. Any
suggestions?
