I came back into work on Tuesday and noticed some minor changes to my desktop settings (such as my Folders names being highlighted as they never were before - refer to image below). No one had touched my computer while I was away. My computer had also restarted itself which usually happens when Windows performs an update. I'm not aware if any update occurred or what it may have been. After opening up FireFox and my other usual applications - Outlook and Excel, I noticed everything lacking background color and some images. All webpages are black and white with minimal graphics showing and links appearing in blue. Outlook, Word and Excel appear to be only in greyscale.
I have checked through all the display settings for every single application and they are all exactly what they should be. I have ran MBAM and Norton and they did not report anything malicious. I ran HijackThis and it suggested some files that may or may not be malicious and I deleted a few - which have not affected anything that I'm aware of. The files I removed pertained to some AOL junk that was initially installed on this computer by a previous user.
I have read several forums suggesting it's a certain Trojan virus but have yet to find anything.
All programs on my computer are working fine but are lacking color. Any idea / advice as to what happened would be helpful. I attached images below of what I described. Hope those help. Thanks in advance!
PS. I also want to add that I signed into my computer's Guest Account and everything is perfect - so it's definitely something only affecting the main user account.
