I would recommend running either MalwareBytes Anti-Malwarehttp://www.malwarebytes.org/products/malwarebytes_pro/http://www.malwarebytes.org/products/malwarebytes_pro/ or Super Anti-Spywarehttp://www.superantispyware.com/http://www.superantispyware.com/ or even both as something is causing your icons to be like that.

Have you added anything new to the computer recently? If so, remove it and see if the issue resolves.
