svchost(DcomLaunch) and other svchost high CPU usage

[Vidosoli]

So lately, I've noticed an immense amount of CPU usage when my PC is idle. This happened very suddenly and after some research I've found the two culpurets! PlugPlay and AudioEndPointBuilder. Since this is more of a Windows 7 problem than anything, I'm worried that if I try to stop either of those 2 proccesses something can really go wrong. I actualy tried the "stop process" option but both Process would keep running normally. I'm pretty sure that it's not a virus/malware problem. At this point I'm not sure as to what I can do more.
