Long time lurker, first time poster, heh. So i have a pretty decent knowledge of computers. Im visiting my brother for the week and his work computer was acting pretty funky. it had some malware of sorts and Trojan.DNSchanger on it. im not sure what the malware was of the top of my head. i put malwarebytes on it, kaspersky, and did all the windows updates (was a lot of them). his computer seemed to be functioning better after then scans, but i didnt get a chance to look at it after it did all the windows updates because it was installing them all when it got shutdown so i just left it that way when we left his office.
the one thing that is still funky with it is that he had me put some more ram in it, so i just opened the case but never actually changed any hardware, but then he got a prompt telling him he needed to validate windows cause the hardware had changed drastically since last start up, but nothing changed at all (it seemed to revalidate when i got all the windows updates on it). when that happened his background changed from his business logo to all blue and all the desktop icons disappeared. i navigated through to the desktop folder and everything is still there, and when i copied a file from somewhere else to his desktop via drag-n-drop it shows up in the desktop folder but not on the actual desktop. im going to be going back to his office soon and looking at it again. what would be the cause/solution for the background changing and icons going away. thanks all!
