Comodo locks up Outlook Express

How can I get cmdagent to stop locking up my OE when I receive emails from Facebook? This only happens with FB mail and when I open Task Manager, I see cmdagent pulling more than 50 percent of my CPU. I am running XP with 3 gigs of RAM. The only way I can even delete the mail is to shut down OE by force and then shut down Comodo------restart OE and then delete my Facebook mails and restart Comodo again. There is no sense in this having to be. I have other computers running AVG and none of them have this problem with FB email notifications.
