AntiSpam 2.1 Will not download emails

I am using 2.5

Hi Sstrikeforce:

You said you e-mails will not come through, we need check several factors.
 1. Do you intall any antivirus products? 
 2. Could you see the animation icon in the systray area when you receiving e-mails? I attached one snapshot of my systray, and identified the icon with a red rectangel.
 3. Do you accounts require SSL conneciton?
