High cpu usage problem | dochara-tollers

Hi,

I have the Panda internet security 2015 software and for 5 days now the PSUAMain and the Application Host Service use 50% of my cpu respectively. The cpu usage is at 100% all the time and my pc is practically useless because I can't run any task.Any idea why this is happening and what can I do to fix it??I have Windows 8.1.

Any help will be apprecited.

I didn't find the right solution from the Internet.
