it doesn't mean that he has the msblast virus,but a good chance.
the RPC restarting started before the msblast came out.
i fixed someones computer that was messed up.
in task manager i killed msblast,mslaugh,treekids,and LSAS(not lsass)then deleted the startup files in regedit.
did a adware and virus scan,installed a firewall,then windows update.
the RPC has something to do with someone sending a file to your computer and having it connect to an irc server,but it is the same way the msblast was sent.
