Endpoint Protection Small Business Edition

I deleted a Trojan FakeAV file today.  The logs now look fine, except the traffic log shows a repeated block.  Here's one:

12/8/2012 3:29:35 PM Blocked 10 Incoming UDP FE80:0:0:0:E2B9:BAFF:FE35:E7D2 E0-B9-BA-35-E7-D2 5353 FF02:0:0:0:0:0:0:FB 33-33-00-00-00-FB 5353  XXXXX Home-PC Default 1 12/8/2012 3:28:34 PM 12/8/2012 3:28:34 PM Block_all 
 

Does this indicate that I still have an infection issue?

Check the Traffic and packet logs, see what traffic is generated during this period that SEP NTP is blocking,

check the firewall rule name "Block_all" it is that traffic hence it is being blocked. I do not think it is trojan traffic.

Is there a remote IP address showing in the log?

Thanks all.  Will review Pete's link and the rule.  Here's what the packet log is generating for the blocked activity, which continues just about every minute.  From other posts relating to similar issues, it looks like this is innocuous, but after yesterday's attack/attempt to use the PC as a spam bot, I just want to be sure.
