Introduction

You need to write a custom script to append additional options (e.g. -Scan) to the virus scanner full path

Finding shortened path for a directory

For Windows environment, if your file path contains spaces (e.g. C:\Program Files), you need to use cmd to find the shortened path for the directory (e.g. c:\progra~1) to remove the spaces.

Open cmd
Navigate to desired directory
Execute the following command
```
dir /x
```
The shorthand for the directory would be displayed

Script Template

For Windows Defender, the command line scanner requires additional options to perform an on-demand scan for a specific file.

Create a batch file script (e.g. c:\atlassian\atlassian-jira-software-7.8.1-standalone\bin\scanner.cmd) using the following template

Replace "c:\progra~1\window~1\MpCmdRun.exe -Scan -ScanType -File" accordingly
scanner.cmd
```
@echo off
REM echo executing scan for file %1
c:\progra~1\window~1\MpCmdRun.exe -Scan -ScanType 3 -File "%1"

REM exit the script by the exit code from MpCmdRun.exe but do not exit the cmd.exe
EXIT /B %ERRORLEVEL%
```
Append the path of the script to the Attachment Checker Virus Scanning configurations in the Full Path for Scanner field
