3 : Scanning the system to Fix Virus and Malicious Files

Run a scan on your home directory or the entire system. For a comprehensive scan:
Run the command in your terminal –

--bell‘ makes a sound when a virus is found.
-i ‘shows only infected files.

For a faster, less comprehensive scan:

sudo clamscan -r --bell -i /home

4 : Review and Remove Infected Files

After the scan, ClamAV will list infected files. You can manually remove these files or use ClamAV to delete them automatically:

To remove infected files automatically: use the following command :

sudo clamscan -r --bell -i --remove /

Caution: Automatically removing files can potentially delete important files. Review the list of infected files before removing them.

5 : Install and use Khunter
