dwm.exe is it a virus?

[Denis Stoikovski]

I saw in one cite that this thing is a virus but when i end the process of it there is no effect sometimes there is its strange in that cite they say this is a confusing virus what should i do? sometimes i run a4 perfectly (for my system) but sometimes it have lag and from today it shows black screen do i need to reinstall the win or? Also the win defender doesn't say that i have a virus.
