error when opening file/folder

When Try to open (double click on mouse) any file/folder/icon deleting error comes.
Error Says:- Are you sure you want to Delete the icon/file/folder from your desktop/folder/drive

Have you downloaded any software recently or altered anything within Windows?

My first point of call would be to perform a anti-virus scan with MSE (Microsoft Security Essentials) which is available in my signature.

Try doing an on-line scan with HouseCalls;

Then download and install Malwarebytes AntiMalware to check and clear any malware;

Be sure to select the free version from the list on the right side of the screen.
