Empty the Recycle Bin.

I've done all the above and extensive cleaning with some tools as CCleaner, biut nothing happened. It is still there!

Try deleting this file in safe mode C:\Windows\nem214.rar

Ok, it seems that the deleting of file is working. I have it in recycle bin. Is this file useful? The PC has no problem for the moment.
Thank you all!

Keep it there for a short while if you are concerned, then delete it when you are sure your PC is ok :).
