System interrupts causing problems?

I have a Windows 8.1 laptop with Intel i7, 8gb memory, 750gb hdd, and 2gb Nvidia video card that is about 3 years old. I've never had any problems until recently. When I play audio or video, there is a lag in the sound and everything freezes for less than a second. It does this anytime, even when just browsing the internet. I watched the performance monitor in the cpu section and there are usage spikes in 3 of the 8 cpu usage graphs when it lags. I think it comes from system interrupts, but I don't know what it means. I tried turning off audio enhancements, as some suggested for this problem, but it did not change anything. I have not made any recent changes to my laptop, so I don't know why this has just started. Any suggestions?

Either your computer is infected by a virus or it is some program messing with your PC. But don't worry there is a solution to both.

Virus Removal:-

This is pretty easy if the problem really is a virus then scan your PC with an antivirus like AVAST and then after that again with Malwarebytes. This should remove the virus but if you have a problem scanning e.g antivirus closing by itself then reply to this comment with the problem.

Program Problem:

Uninstall any program that you recently installed it can be an antivirus or anything. If all else fails PM me and then we will see what can be done.

You are the unhappy owner of a virus.

Now you must get educated how to get rid of it or pay someone to do so :(
