Force kill processes in ubuntu

I just had a problem with my skype that I couldn’t login due to previous instances having been closed but for a mysterious reason the process was still hanging over there. So, in short I couldn’t log into my Skype. So here is what I did to kill those processes you see below:

root@support-desktop:/home/support# ps ax | grep skype
2828 ?        Sl    16:33 skype
21721 ?        Sl     0:04 skype

As seen above, there is a skype process with PID # 2828 which is still holding tight and needs to be killed. So here is the command to kill this process:

root@support-desktop:/home/support# kill -9 2828
