1. How to use Kaspersky World:
  2. 1. Turn off Kaspersky Self-defence
  3. 2. Exit Kaspersky;
  4. 3. Start KW, go to Trial Life and press "License Antiblock";
  5. 4. If you have win x64 run bcdedit.exe -set TESTSIGNING ON;
  6. 5. After resetting system will reboot;
  7. 6. After system start KW will start in "tray-mode". You can see it in tray;
  8. 7. Wait until KW says "Operation finished successfully. Reset activation now?". This operation can take from 20 minutes to 1 day. Kaspersky must be turned on! Then you can reset activation again. Before you did it turn off self-defence and exit Kaspersky;
  9. 8. Finally after system restart you can use Trial License again! Also if you have x64 windows and you did "4"-step you can turn off test mod by bcdedit.exe -set TESTSIGNING OFF.
