Resetting the ClamAV database


Overview:
I occationally get the following error with the Clam system on my SME server:
<Date Stamp> ClamAV update process started at <Date Stamp>
<Date Stamp> main.cvd is up to date (version: 54, sigs: 1044387, f-level: 60, builder: sven)

<Date Stamp> Update failed. Your network may be down or none of the mirrors listed in /etc/freshclam.conf is working. Check http://www.clamav.net/support/mirror-problem for possible reasons.
So I want to fix it

Procedure:
Step Terminal Command What it is doing
1 
service clamd stop
 Shutdown clam so clamd.socket file is removed
2 
cd /var/clamav
 Navigate to clamav folder
3
 
rm -f /var/clamav/*
 Remove ALL files from folder to provide clean slate for update process
(you could skip the -f & confirm every file delete for safety)
4
 
service clamd start
 Restart clam
5
 
freshclam -v
 Update sigs 

Note:  if you are bandwidth poor or on slow connection then don't delete main.cvd
