Thank you for your response. I just tried to open KIS. But did not open, it was not there in my computer. When I searched C drive, no installation files were there. It was quite obvious that my computer has been infected with virus though it had KIS (with valid license, 399 days remaining). I did not remember the error, but some error it showed. The word ‘UNINSTALL’ may be wrong in my case. May be it stopped functioning. But it crashed, I don’t have proof to substantiate my arguments. But kaspersky poorly failed.
