-i, to print infected files,

–bell, a bell sound if it detects a virus,

/home/, directory we intend to scan – you can use directories of your choice

This command only scan directories and provides us with the list of infected files. But, what if we plan to move infected files to some other directory. It could be a better choice as removing an infected file may break our system. Hence, we tread with caution and move the infected file to some other directory. We need to type the following command in terminal –

clamscan -i -r --move="/home/<home-directory>/Downloads/" /home

The above command will scan the directory /home/ and if infected files are detected then, it will move those files to the directory /home/<home-directory>/Downloads/.

Type clamscan -h for more options.
