since it took me some time to got the GData Internet Security for HomeServer integrated into the hmailserver I would like to share my solution with others in case they want to do the same thing.
Since the GData command line scanner is not supporting return codes I found another way to use it in hmailserver.
First you need to create a small batch script (I named it "virusscan.bat") and you place it where you want (Adjust the SCANBINARY value to your environment).virusscan.bat
set SCANBINARY="C:\Program Files (x86)\G DATA\AVKClient\avkcmd.exe"
%SCANBINARY% /scan(e0a0):%FILE% /silent /nologo /noprogress /log(t0h0i0):%LOGFILE%
FOR /F "usebackq" %%A IN ('%LOGFILE%') DO set SIZE=%%~zA
if %SIZE% LSS %MAXBYTESIZE% (
echo.Virus scanner did not find a virus or generated a message or warning.
) ELSE (
echo.Virus scanner find a virus or generated a message or warning.
echo.Checking if a real virus was found or only a message or warning was generated.
for /f %%a in ('type %LOGFILE%') do (
if "%s%"=="!s:@@@%INFECTEDSTRING%=!" (
echo.Virus found. "%LOGFILE%" contains an entry which begins with "%INFECTEDSTRING%".
if "%RC%" == "0" (
echo.No virus found.
This script is doing the actual scan.
It will call the GData virus scanner and in case the scanner writes entries in a log file (This is the case in case of a virus has been found or in case a file could not be opened or in case of other messages) it will check if it finds entries starting with the word "Infeced" which indicates a virus message.
In case of a virus was found it will not delete the LOGFILE but you can change this if you want
In the hmailserver Anti-Virus scanner executable you need then just to specify (Place the double quotes exactly as shown):
"<PATH TO THE SCRIPT>\virusscan.bat" %FILE%
and Return value should be 1.
I know that the script might not be perfect and could be enhanced but for me it does what it should.
