NOTE: Kaspersky detects the KRT_2.1.exe file as a hack tool (it is the trial reset, it's not a virus)
and it WON'T let it run. So you better add it to the exclusion list if you want to reset the kaspersky trial.
1. Install Kaspersky 2014 (it will automatically remove any previous versions)
2. Restart computer
3. When the trial is approaching to it's end, disable Self-Defense (Settings - Additional - Self-Defence --> Uncheck box, click apply)
4. Close kaspersky from the TASKBAR (just pressing X won't close it)
5. Run KRT_2.1.exe as an admin, then click the left button.
6. Open Kaspersky, which is now reseted
7. Add KRT_2.1.exe to the exclusion list
8. Enjoy!
