Ubuntu: CLAMAV not working



Question:

After installation of CLAMAV and try to scan I see this error. How do I solve this? Thanks

clamscan scan  LibClamAV Error: cli_loaddbdir(): No supported database files found in /var/lib/clamav  ERROR: Can't open file or directory    ----------- SCAN SUMMARY -----------  Known viruses: 0  Engine version: 0.98.7  Scanned directories: 0  Scanned files: 0  Infected files: 0  Data scanned: 0.00 MB  Data read: 0.00 MB (ratio 0.00:1)  Time: 0.003 sec (0 m 0 s)  


Solution:1

The error message tells the tale: LibClamAV Error: cli_loaddbdir(): No supported database files found in /var/lib/clamav and Known viruses: 0

You need

clamav-freshclam - anti-virus utility for Unix - virus database update utility  

Also ensure that user running the scan has read access to /var/lib/clamav.


Solution:2

Steps 1-3 below include commands run in a terminal. Please read carefully so that you understand what you are doing.

  1. Remove potentially bad AV installations:

    sudo apt-get remove clamav   sudo apt-get remove clamtk   sudo apt-get remove freshclam  sudo apt-get clean  sudo apt-get autoremove  
  2. Reinstall AV:

    sudo apt-get install clamav        #Terminal Version  sudo apt-get install clamtk         #GUI version  
  3. Update AV Database:

    sudo freshclam               #takes ~30 minutes to download definitions  
  4. Configure AV & Scan:
    This example uses clamtk only

    clamtk                      #Opens GUI  

    toggle all options under Settings tab:

    Network

    • toggle proxy and type http://127.0.0.1
    • toggle / reselect **No Proxy **(to gray out what you entered above)

    Update Assistant

    • toggle manual update option and click apply and back
    • toggle automatic update option and click apply and back

    You should now see updated definition count

    Scan a Directory

    • select directory you want scanned. For system scan I toggled the entire system (not just /root or /usr)
    • Click scan and a progress box will appear.

Final Note: typing the phrase --help (without quotations) following command gives some hints. With APT commands you can pass the option -y to say yes to installing all dependencies for the requested package.

This is what I had to do to get clam working, perhaps a glitch for both clamtk and clamav (problem with both). Hope this helps someone else!!!


Solution:3

Install clamdscan by running:

sudo apt-get install clamdscan  


Solution:4

I had to manually create and set the directory /var/lib/clamav to 777, then run freshclam. This downloaded all the signatures and updated clamav, and all seems well now.
