I have a strange problem. When I right click on a file (.exe, .dll, .jpeg, ...) I end up with a screen as in the attachment. (It should be like in http://images.maketecheasier.com/200...py-move-to.gif
However, there is no problem when I right click on desktop, it is as it should be (no blue band). I have a desktop PC and a laptop and both has the same problem. I tried system restore but no solutions
What can be the reason? A virus or a malware (despite Avira and A-squared installed)?
