Unable to Complete Step 2 of Cleaning Procedure

I have an infection that has prevented me from being able to turn off the User Account so I am unable to proceed with Step 3 of the Read and Run me first. What should I do at this point?

If it is of any help, these are the problems I have noted since my computer became infected.

1) Although desktop and file icons in Explorer are visible, there are no file or icon names visible except in the "folders" drop down menu were folder names are visible but not file names. Folder names are not visible in the viewing window itself.
2) The search function from Start and in the Explorer window has been inactivated. Typing “run” in the Start search window and hitting enter causes a window to open for a split second and then close again. Typing anything else in the window and hitting enter does nothing visible at all.
3) Windows update is disabled and now I am also unable to open the update website. I am not redirected; just can’t connect.
4) At one point early on, I noticed that when windows log in screen appeared there was a choice to “switch users”. That was new. At the time, I checked user accounts in the task manager but only saw one account listed, my own.

The Help function from the main Start window is still operative which has allowed me access to CMD function and REGEDIT. It didn’t work for Windows Update or User Account

I have no idea how my computer became infected. It is an office computer that only I use. It was working fine when I left for vacation, and when I returned, the first thing I noticed was that my desktop resolution had changed and that there no longer where any icon names. My computer was turned off while I was away. My Malewarebytes log does not show any logs for the days I was gone. There are people who could have accessed it, but there really was no reason to, as they have their own computer and there is nothing of value or interest to anyone else on mine. I am baffled.

My Eset antivirus said I had a Win32/TrojanDownloader.Banload.LCTGMFCtrojan which it could not clear, but I was able to remove it with Kapersky’s online virus scanner.

I am running Vista on a Dell Studio 1737.

Thank you for your assistance.

 

Thanks for the help. I was able to run all the scans without difficulty despite not being able to deactivate the user account.

 

Here is the last file. Thanks again.

 

Thanks. It is good to know that I no longer seem to have an infection.

The problem I am still having is that all icons and folders and files are missing visible names. The files themselves are not gone, just there names. If I right click and check properties, the name can be seen, or if I copy to another computer the file names are visible.

Also the search function from Start and within Explorer file window no longer works.

 

Yes, I did, several times in fact. Question: Is unhide.exe supposed to restore the names of files, or just files that are hidden?

Another question: If my computer no longer appears to be infected, should I remove Combofix?

Thanks for the help.
