How do I change when snort rules update

Hello All,

My EFW mysteriously slows to a crawl the same time everyday (at about 2:30 PM).  The throughput is very slow and the hard drive thrashes like mad.  I checked the logs it looks as though it is updating the snort rules at this time
I have Intrusion Prevention set to update every day so that would make sense. 

Is there a way to change when it updates the snort rules?  2:30 AM for example would be preferable.

Thank you in advance,

Timoteo
