There have been 26 updates in the last 7 days, which is slightly higher than usual.

From the Troubleshooting FAQ:

>> If you are running ClamAV 0.8x or later, you can check for database update as often as 4 times per hour provided that you have the following options in freshclam.conf: DNSDatabaseInfo current.cvd.clamav.net DatabaseMirror db.XY.clamav.net DatabaseMirror database.clamav.net Replace XY with your “country code”:iana. If you don’t have that option, then you must stick with 1 check per hour.
