ClamAV v.0.98.5 is installed on Server 2008R2 as external antivirus with Kerio control.
After executing freshclam.exe one of command should be executed as set in freshclam.conf:

# Run command after successful database update.
# Default: disabled
OnUpdateExecute c:\clamav-devel\Success.bat

# Run command when database update process fails.
# Default: disabled
# OnErrorExecute Failed.bat
OnErrorExecute c:\clamav-devel\Failed.bat

# Run command when freshclam reports outdated version.
# In the command string %v will be replaced by the new version number.
# Default: disabled
OnOutdatedExecute c:\clamav-devel\Outdate.bat

But really nothing happens
The same was with older versions or Clamav.

What is wrong in this config?

What do you mean nothing happens? Do you mean the tasks you are trying to perform are not working or do you mean the tasks perform but nothing happens after that.

How long have you been using ClamWin? Was it working okay for you previously?

It looks to me like you are running some custom scripts--scan after update, etc.. I can never get ClamWin to do much via the command line. I do not believe that the developers have allowed all the Clam AV command line functions in ClamWin. For the command line, you have to know what you are doing, as you are basically on your own. You might check the Clam AV documentation for some help.

Regards,

As I can see by .bat files never executeed at all neither if update is successful or if it failed - no window appears and nothing is performed.

But these settings in config are certaily not ignored. If I make some mistake there I get error message during update.

I just want Clam to notufy me by e-mail about update results...

I found nothing in documentation about by problem.

You said this has happened on older version and ClamAV, then this is most likely on ClamAV's side. You should contact them about this issue here: https://www.clamav.net/contact.html

Alternatively, you can set the email notifications in the ClamWin configuration under email alerts.
