Not able to change desktop background

[WonderBot]

I have a user with a Windows 7 64 bit machine on our domain. A few days ago he recieved a nasty malware virus and we removed it with our virus tools. However, his desktop is not the way it use to be before the malware. The obvious problem being his desktop background is black and it does not change. When I try to change it in control panel to Architecture or Landscapes, nothing happens, just the color of the taskbar changes. Also, Ive noticed that his "Accessories" folder is missing.

I tried adjusting settings in the Ease of Access section, but still does not work.

Open CMD with Admin rights and do a SFC can.

Welcome to Seven Forums.

I'd try Unhide first since you said it happened from a "nasty malware virus".

Unhide.exe is a program that will revert many of the changes on your computer caused by the FakeHDD family of rogue anti-spyware programs. This family of rogues pretends to be a system optimization program that will solve errors with your computer’s hard disks, memory, and performance. It will also display fake alerts stating that your computer has numerous computer issues and prompt you to purchase the program in order to resolve these issues.

These kind of problems are generally caused by some 'bad' registry keys and/or group policy settings often used by these nasties.. Its possible that there could be some remnant left causing the problem.
I'd like you to run a full scan with Malwarebytes and post the results here as its quite good at detecting and removing these.

Already tried Malwarebytes, and it detected nothing. Then ran a scan with Trend Micro and it found a few issues.

Fixed it!!!

I went to C:\Users\username\AppData\Roaming\Microsoft and then right-click on the Windows folder, then click Properties. Uncheck the Hidden box and then click Apply and then close.

This brought the accessories folder back, and the desktop backgrounds now show. I'm still not sure how the hell that happened, dam malwares!

the SFC scan found nothing, but thank you for that tip.

What antivirus are you using. You may want to switch if it let that malware throught and didn't do anything. Or, I recommend you keep malwarebytes on your systems and run a scan with it about once a month, more often if you would like.
