Currently the new test_handler.py function downloads the ClamAV definitions and scans test files which are created in the container upon running the python file.

It returns:

ClamAV Definitions downloaded successfully.
Scan result for /var/task/test.txt: Clean
Scan result for /var/task/eicar.txt: Infected
Scan result for /var/task/test space.txt: Infected
/var/task/test: No such file or directory
WARNING: /var/task/test: Can't access file
space.txt: No such file or directory
WARNING: space.txt: Can't access file

I need to rectify this error to allow for testing in the event of a file with a space in the name.

Edit 31st Oct. The approach here is wrong at the moment. Pivoting.
