I think it's a mistake to not create at leat man page for clamav, wich is the name of the package.
If you want to check all files of the system, then you should use `clamscan -r --bell -i --exclude-dir="^/sys" /` because in `/sys/` are no real files and not excluing it would cause reading errors. http://askubuntu.com/questions/591964/clamav-cant-read-file-error
`sudo freshclam ERROR: /var/log/clamav/freshclam.log is locked by another process ERROR: Problem with internal logger (UpdateLogFile = /var/log/clamav/freshclam.log).`

clamscan -r -i --bell --file-list=/home/nav/ClamScanTheseFolders.txt
/media/nav/someFolder1 /media/nav/someFolder2 /opt/someFolder/somefile
