I've manages to stop the shared access service

(cmd prompt - "sc stop SharedAccess" and "sc delete Shared Access")

I've killed off the svcvhost entries with Hijackthis

I've deleted the windows\system32\svcvhost.exe file with killfile

everything looks good

I did all this once and it was fine for 15 minutes then it all came back - everything - no idea why

I've done it again and it's stayed fixed for 20mins or so - looking OK at the moment.

Still no command prompt and no windows firewall

current log is:

Hey there Bob and welcome to Bleeping Computer's security forum.
My name is David, I will be helping you with your log today.

So far i think you've done a pretty grand job of removing all the malware off your system as the Hijackthis log above is now clean. My only concern is that you say you removed it all before and it came back again. This could be anything from a reinfection due to your lack of protection (no antivirus installed for example), or you have some hidden downloaders on your system which keep reinfecting you as long as you have them on your system. I'll do my best to root out the bad files if they are present, then try and repair any damage done by the malware.

I have seen cmd.exe get corrupt a couple of times for no apparent reason, though suspected malware. Or the default path to c:\windows\system32 may be lost but that would cause a host of problems. But you could try start/run c:\windows\system32\cmd.exe to see.

If not try start/run c:\windows\servicepackfiles\i386\cmd.exe
and see if that copy works. If so then copy it over the one in c:\windows\system32. There is also a cmd.exe in c:\i386, but that is the pre-sp2 version I believe.

If not, try start/run c:\windows\system32\command.com - the old command interpreter. If that doesn't work either then likely the problem lies in the core of Windows and a repair might be in order. Let me know how that goes.

I saw in your other thread that the task manager isn't working.
A simple regedit should be able to fix this.

Please open notepad and and copy and paste next bold in it:
(don't forget to copy and paste REGEDIT4)



[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects\LocalUser\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"**del.DisableTaskMgr"=" "


[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]

Save this as "fix.reg" Choose to save as *all files and place it on your desktop.
It should look like this: Posted Image
Doubleclick on it and when it asks you if you want to merge the contents to the registry, click yes/ok.

One thing we also must do is install an antivirus, you don't have one active!
This is somewhat suicidal in today's digital world.
You need to install an antivirus program as soon as you can and run a complete scan of the computer.
AVG and Avast are excellent, free antivirus programs..
Never install more than one antivirus on your system - several together can cause problems and decrease performance.

I also see that you have lost your admin rights.
Can you logon to the Administrator account in Safe Mode? If so, you should be able to restore administrator rights to the user accounts there.

If that doesn't work, while still in Safe Mode, Administrato account, try this: Go to Start>Run, type in control userpasswords2 (note the space after "control"), click OK.

Double click on an account you want to change, then go to the Group Membership tab, select Administrators in the drop-down list, click OK. Do that for each user account.
If you get the admin rights back, see if you can turn back on the firewall.

Now, let's have a look for any remaining malware on the computer.
Please download, install, and update Ewido anti-spyware
Load Ewido and then click the Update tab at the top.
Under Manual Update click Start update.

After the update finishes (the status bar at the bottom will display "Update successful")
Then click on the Scanner tab at the top.
Click the "Settings" tab and then change the recommended action to Quarantine.
Click Automatically generate report after every scan.
Click back to the "Scan" tab and then click on Complete System Scan.
This scan can take quite a while to run, so be prepared.
Ewido will list any infections found on the left hand side.

When the scan has finished, it will automatically set the recommended action.
Click the Apply all actions button.
Ewido will display "All actions have been applied" on the right hand side.
Click on "Save Report", then "Save Report As".
This will create a text file. Make sure you know where to find this file again (like on the Desktop).
Close Ewido and reboot!! I need the log later.

Please download Combofix to your desktop.
Doubleclick combo.exe to launch the application.
Follow the prompts that will be displayed on the screen.
Don't click on the window while the fix is running, because that will cause your system to hang.
When finished, it should produce a log, combofix.txt.
Post this log in your next reply together with a new hijackthislog.
Also post the ewido log.

Hope this helps, let me know how it goes.
