How to recursively scan a folder with ClamAV in Python

Time:12-09

I want to build a python script to scan scan my linux computer for viruses with clamav. But I don't know how to recursively select every filename and scan it. I just need a algorithm to select the files. The function for scaning a single file, already exists. I thought about something like this.

slect every file:
  clamscan(file)

To recursively scan a folder with ClamAV in Python, you will need to use the clamav.scan_file or clamav.scan_stream method from the clamav library. The scan_file method will scan a file on disk, and the scan_stream method will scan a stream of data (such as a file that is being read from disk).

Here is an example of how you could use the scan_file method to recursively scan a folder and its subfolders for viruses:

import clamav
import os

# Set the path to the folder you want to scan
folder_path = '/path/to/folder'

# Create a ClamAV instance
clam = clamav.ClamAV()

# Scan the folder and its subfolders recursively
for root, dirs, files in os.walk(folder_path):
    for file in files:
        # Get the full path to the file
        file_path = os.path.join(root, file)

        # Scan the file
        result = clam.scan_file(file_path)

        # Check the scan result
        if result is None:
            print(f'{file_path} is clean')
        else:
            print(f'{file_path} is infected with {result}')

This code will scan the folder and its subfolders recursively, and print a message for each file indicating whether it is clean or infected with a virus.

Alternatively, you could use the scan_stream method to scan files as they are being read from disk, like this:

# Import the clamav and os modules
import clamav
import os

# Set the path to the folder you want to scan
folder_path = '/path/to/folder'

# Create a ClamAV instance
clam = clamav.ClamAV()

# Scan the folder and its subfolders recursively
for root, dirs, files in os.walk(folder_path):
    for file in files:
        # Get the full path to the file
        file_path = os.path.join(root, file)

        # Open the file for reading
        with open(file_path, 'rb') as f:
            # Scan the file stream
            result = clam.scan_stream(f)

            # Check the scan result
            if result is None:
                print(f'{file_path} is clean')
            else:
                print(f'{file_path} is infected with {result}')

This code will do the same thing as the previous example, but it will scan the files as they are being read from disk, which can be more efficient in some cases.
