Manually Update the Kaspersky Anti-Virus’s signature

1. On Desktop, extract av-i386-cumul.zip to a folder. In this example, I extract all files to /root/Desktop/Updates/.

2. Back to Webmin, click on KeepUp2Date in Other -> KAV 5.7 for UNIX WS.

3. On KeepUp2Date menu, browse to misc settings. Check ‘Use update server url’ and ‘Use update server url only’ and change ‘Update server url’ to the folder where you have extracted the signature files. In this example, it is ‘/root/Desktop/Updates/’. And click Save.
Note: The ‘Update server url’ path must be follow with ‘/’.

4. Open Terminal and type the command below to update the signature.
/opt/kaspersky/kav4ws/bin/kav4ws-keepup2date

5. Waiting until the update is finished, you’ll see some error message because Kaspersky Anti-Virus hasn’t started yet.

6. Now the signature is up-to-date. Browse to Key Info on Webmin again, the license info has been shown correctly.
