I'm not sure where to post this (here or Vista). I had the msa.exe trojan with the Internet Explorer fake website pop-ups (which AVG blocked and identified as TrojanHorse BHO.JQI.dropper from avrapiddown.info) which I cleaned with Malwarebytes' Anti-Malware. I'm pretty sure I cleaned the comp up but I still cannot see my desktop folders, files or icons. I can add a folder and it shows up in the Desktop folder under my user but I can't see it or manipulate on my desktop. I still have my wallpaper showing and the taskbar and start menu and everything functions just no desktop. Does anyone have a clue how to fix this.

I am running Vista Premium 64 Service Pack 1.

Hello please run ,, sfc /scannow
NOTE for Vista users..The command needs to be run from an elevated Command Prompt.
Click Start, type cmd into the Start/Search box,
right-click cmd.exe in the list above and select 'Run as Administrator'

You will need your XP CD handy.

Open Windows Task Manager....by pressing CTRL+SHIFT+ESC

Then click File.. then New Task(Run)

In the box that opens type sfc /scannow ......There is a space between c and /

Click OK
Let it run and insert the XP CD when asked.

When complete it said there was still some corrupted files it could not fix, that there was a log file named cbs.log and to reboot. I still have a broken desktop after a reboot, however. Hmm. :thumbsup:

It may be a simple fix.. Is the desktop still the same or did anything change?
Right-click on your Desktop and highlight Arrange Icons By (XP) or View (Vista). In the menu that pops up, Show Desktop Icons probably won’t have a check mark next to it because hopefully, it somehow got checked off. So click on Show Desktop Icons. It takes several seconds for Windows to reset the Desktop.

The possibilty of malware is there.
Next run ATF and SAS:
Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.


Please ask any needed questions,post logs and Let us know how the PC is running now.

We can also try a System Restore,but this will most likely also restore the removed malware and we'll need to do it again.

Well it was the simple fix. I've been using computers since 1992 with my 1st computer, a 386 SX with no hard drive and (2) 5.25 floppies. You would think that with that time and a BS in Computer Software Engineering Technology I would have seen that. I only just started using Vista a few months ago when I put in a new mobo, CPU, RAM upgrade and needed Vista 64. Of course the same option is in XP too. I looked at that numerous times too, to get to Personalize but never thought to look at View. Oh well, thanks alot for the help. It was from this board I figured out how to get rid of the malware itself too. Keep up the great work and thanks again for giving me back my desktop.

You're welcome and glad it's fixed. Sometimes you have to step back or just get another opinion.. That's why they pay me the big $$ :thumbsup: ( No we all volunteer here.
Thanks for your kind words.

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
