You can disable notifications DrWeb. This, must make numerous corrections to the database of Plesk:
1.Connect to the database:
"%plesk_dir%\mysql\bin\mysql" -uadmin -padmin_password -P8306 psa
2. Check the record for antivirus notifications is present in the table psa.misc. You can check this by running the following SQL query:
select val from misc where param = 'AntivirusNotifyAdmin';
The query should return the following values:
0 – disabled notifications;
1 – notifications enabled;
Notifications can be enabled or disabled by changing the setting through the following queries:
To disable notifications
update misc set val='0' where param = 'AntivirusNotifyAdmin';
To enable notifications
update misc set val='1' where param = 'AntivirusNotifyAdmin';
You can add a nonexistent record by running the following query:
insert into misc values ('AntivirusNotifyAdmin','0');
Notifications can also be activated for the sender and / or recipient of the infected email, adding the following values:
‘AntivirusNotifyAdmin’ – parameter controls the notifications to the Plesk administrator.
‘AntivirusNotifySender’ – be notified to the sender of the infected e-mail about.
‘AntivirusNotifyRecipients’ – will notify the recipient of the infected e-mail about.
