Hi

   You can follow the below step to restore all the Icons that are made hidden. This sometimes might happen after a Fake Application Infection Removal ( a side effect). The below command will reset all the files to be non-system and unhides them, Because the Infection will assign System File attribute to the files in start menu, Desktop, My Documents, etc.

    Open Command Prompt with Admin credentials: start->type cmd -> right click on cmd.exe ->Run administrator ->type cd\  ->type attrib -h -s /s /d   -> Hit enter and let it run and once finished you can check your icons. Let us know how it goes.
