Plesk for Linux: disable Dr Web update cron notifications

To disable Dr Web update cron notifications via e-mail in Plesk for Linux:

1. Edit file Dr Web configuration file /etc/drweb/drweb32.ini using your favorite editor. Mine is vim:

# vim /etc/drweb/drweb32.ini

# CronSummary = yes
# —>
CronSummary = no

2. Edit file /etc/cron.d/drweb-update and add to the end of string >/dev/null 2>&1

# more /etc/cron.d/drweb-update

*/30 * * * * drweb /opt/drweb/update.pl >/dev/null 2>&1
#

3. If user drweb has cron jobs

# crontab -u drweb -l

55 2,7,12,17,20 * * * /opt/drweb/update.pl
change it to:
55 2,7,12,17,20 * * * /opt/drweb/update.pl >/dev/null 2>&1

4. If file /usr/local/psa/etc/drweb-update exists

# vim /usr/local/psa/etc/drweb-update 

Change its content from:

#!/bin/sh
exec /opt/drweb/update.pl

to:

#!/bin/sh

exec /opt/drweb/update.pl >/dev/null 2>&1
