Kaspersky Databases Are Corrupted

Posted on by

I am using Kaspersky AV 7.0.1.321 a.b.c.d on XP Pro sp2. I got the database corrupted message on reboot twice today. The first time I rolled back my database and updated manually. On reboot the second message about database corrupted appeared. This time I rolled back the database but did not updated manually nor have I rebooted. Kaspersky has been working fine but yesterday it turned itself off and I get a message saying 'Databases are corrupt' and 'Cannot update license key is missing' If I select update it doesn't seem to do anything. IT IS A GENUINE PACKAGE not a pirate copy. How can I fix this? When I rollback everything goes back to normal but then soon as I restart the problem is back. Oct 04, 2019 'Databases are Corrupted' & 'Databases are extremely out of date' On a single client. Open and Administrative command prompt (type CMD at the run line and hit Ctrl-Shift-Enter) Run the following commands: cd - press Enter; cd 'Program Files (x86) LANDesk LDClient Antivirus' - press Enter; ldav.exe /updatefrominternet - press Enter. Kaspersky is displaying messages saying updates need to be made, updating and getting to 100% but never finishing the update then use the following fix. Right click the Kaspersky system tray icon (usually in the bottom right of the screen). Under Update, click Settings. After Kaspersky Total Security 2016 has started, you may encounter the error Databases are corrupted. The system protection indicator in the main view turns red and the Databases are corrupted message is displayed. To fix this problem, use the methods below.

‘Black list’ of key files is a Kaspersky Antivirus database that contains the information about key files which cannot be used by Kaspersky Lab software any more. There is some number of ways a key can end up in this database:

  • The key has been replaced with a new one as stolen;
  • The key has been replaced with a new one as malfunctioning;
  • The key was available on pirate servers (for free download).
  • The key has been replaced with a new one after being activated on a computer with incorrect system time/date;

Error Message:

The ‘black list’ of key files is named blst. This file is saved and downloaded along with databases (anti-spam, anti-virus, network attacks). Kaspersky Lab software cannot function without a ‘black list’ file.

Kaspersky Lab software notifies hereof and stops functioning:

  • if the file blst is damaged;
  • if there is no blst file on your PC;
  • if the Kaspersky Endpoint Security you have installed is using a key file from the ‘black list’;
