ClamAV Vulnerability Scanning Tool

ClamAV is an open-source antivirus software used for detecting and removing viruses, trojans, and malware. Below are the basic usage methods for ClamAV:

1. Install ClamAV:

   For Debian/Ubuntu systems, use the following commands to install:

   sudo apt-get update  
   sudo apt-get install clamav clamav-daemon  
   

   For CentOS/RHEL systems, use the following commands to install:

   sudo yum install epel-release  
   sudo yum install clamav clamav-update  
   

2. Update the virus database:

Use the following command to update ClamAV's virus database:

sudo freshclam  

If you encounter permission issues, try starting the freshclam daemon with sudo systemctl start clamav-freshclam.

3. Scan files and directories:

   Use the following command to scan a single file:

   clamscan /path/to/your/file  
   

   Use the following command to scan an entire directory:

   clamscan -r /path/to/your/directory  
   

   To automatically delete infected files during the scan, add the --remove parameter:

   clamscan -r --remove /path/to/your/directory  
   

   To generate a report after the scan is completed, add the --log parameter and specify the path for the report file:

   clamscan -r --log=/path/to/your/logfile /path/to/your/directory  
   

4. Use the ClamAV daemon for scanning:

To use the ClamAV daemon for scanning, first ensure that the daemon is running:

sudo systemctl start clamav-daemon  

Next, use the clamdscan command to perform the scan, for example:

clamdscan /path/to/your/file  

or

clamdscan -r /path/to/your/directory  

5. Schedule regular scans:

To perform regular ClamAV scans, you can use cron jobs. First, create a shell script, such as clamav_scan.sh, and add the following content:

#!/bin/sh  
clamscan -r --log=/path/to/your/logfile /path/to/your/directory  

Add execution permissions to the script:

chmod +x /path/to/your/clamav_scan.sh  

Next, edit the cron jobs using the crontab -e command and add a line to set up regular scans (for example, to run every day at 1 AM):

0 1 * * * /path/to/your/clamav_scan.sh
