Automate ClamAV antivirus

#!/bin/bash
# Filename: ClamAV-scan
# Version: 291110
# Author: robz
# This runs clamscan via a "user crontab", scans reports & logs to your home
# directory every 3 days, or alter to your prefs. "30 19 */3 * * export
# DISPLAY=:0 && /home//.scripts/ClamAV-scan > /dev/null 2>&1" all on one
# line without the enclosing quotes.
# The patched notify-osd package is reqd. see this page for an explanation.
# http://www.webupd8.org/2010/05/finally-easy-way-to-customize-notify.html
# You might also need to "sudo chmod 444" some files to allow read access for
# "others", something to check if script fails see below.
