I have a Win xp pc recently infected with windows recovery virus. Cleaned with malwarebytes, unhid files and folders so programs and hidden files visible, task manager accessible. Everything appears to work only Unable to copy anything to the desktop. Items in the desktop folder for the logged in user do not appear on the desktop but work fine if accessed within the folder. Get a circle with a line through it when attempting to copy items there. Changed the desktop theme thinking desktop had been replaced with a webpage. DEsktop themes change as expected but no icons or files. Just a blank desktop.
