while i have my aol instant messanger still on, is my
computer open to getting a virus because of this even

Keeping multiple users logged in doesn't really make you any more vulnerable
than leaving a single user logged in. You may have more junk to siphon
through in your auditing (if you have auditing enabled), but that's about
it. However, leaving multiple users logged in simultaneously will eat up
system resources.
