How to Uninstall Kaspersky Antivirus Completely?

I need your assistance to remove or uninstall Kaspersky Antivirus program. This software worked greatly for the first year, but I don’t think it is still the one I like. Many problems appear. It froze constantly. Whenever I tried to do something, I always got that spinning wheel cursor. I have to wait, sometimes 5 minutes. My PC barely works for me. When using the PC, it popped up messages like “connecting to Kaspersky servers”, “fail to connect to Kaspersky servers” and “Kaspersky stops working” etc. I tried to quit the software, but the exit option never loaded. I even could not stop it with Task Manager. I don’t know what else what can I do to fix the problem. Would you please help me uninstall Kaspersky Antivirus?
