I'm trying to help a friend who's computer was compromised by a houseguest's surfing... AVG reports a Trojan Horse Downloader.Generic5.DHD and states the affecting file is mshta.exe under the "S?curity" folder within the main user's My Documents.... Here is the HiJack This log..... Any help would be greatly appreciated!

_________________________________
Welcome to the Forums.

The fixes we will use are specific to your problems and should only be used for this issue on this machine.

Please only use this topic to reply to. Do not start another thread.
If any other issues arise let me know.
The process is not instant. Please continue to review my answers until I tell you your machine is clear. Absence of symptoms does not mean that everything is clear. So lets do this to the end!

• All hijackthis logs I ask for should be done in normal mode ( not safe mode)
• These logs should be done last after you have followed my instructions in the previous post.

Please if you decide to seek help at another forum let us know. There is a shortage of helpers and tying 2 of us up is a waste of time.
If you have any questions about any advice given here please STOP and ask!

It looks like you have been infected by a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and Download and Execute files

Its very possible that anything could have been installed on your computer by the remote attacker, including opening other backdoors and installing rootkits. While we can attempt to clean what we see in your logs, we can't guarantee that your computer will be completely in the clear since we have no way of knowing that has been done to the computer. Your computer could be completely compromised at this moment. It may be prudent to backup your information, reformat, and reinstall.

More information on Remote Access Trojans can be found
here

I suggest you do the following immediately:

• Call all of your banks, credit card companies, financial institutions and inform them that you may be a victim of identity theft and to put a watch on your accounts or change all your account numbers.
• From a clean computer, change *all* your online passwords -- for email, for banks, financial accounts, PayPal, eBay, online companies, any online forums or groups you belong to.
• Do NOT change passwords or do any transactions while using the infected computer because the attacker will get the new passords and transaction information.

If, however, you decide that the computer is not used for any sensitive work, or if you do not wish to reformat at this time, I can help you clean your computer to the best of my abilities.

Should you have any questions, please feel free to ask.

Please let me know what you decide to do in your next post.

Should you decide to clean this machine start by doing the following.





_________________________________________

I see signs of 2 anti Virus programs running. Nortons and AVG7. This is not a good idea.
They will conflict with each other and fight for resources slowing your computer way down and providing you with much less protection.
I strongly recommend you remove one of them through Add/Remove programs now,




__________________________________________

Download SDFix and save it to your Desktop.

Double click SDFix.exe and choose Install to extract it to its own folder on the Desktop. Please then reboot your computer in Safe Mode by doing the following :

• Restart your computer
• After hearing your computer beep once during startup, but before the Windows icon appears, tap the F8 key continually;
• Instead of Windows loading as normal, a menu with options should appear;
• Select the first option, to run Windows in Safe Mode, then press "Enter".
• Choose your usual account.

• In Safe Mode, right click the SDFix.zip folder and choose Extract All,
• Open the extracted folder and double click RunThis.bat to start the script.
• Type Y to begin the script.
• It will remove the Trojan Services then make some repairs to the registry and prompt you to press any key to Reboot.
• Press any Key and it will restart the PC.
• Your system will take longer that normal to restart as the fixtool will be running and removing files.
• When the desktop loads the Fixtool will complete the removal and display Finished, then press any key to end the script and load your desktop icons.
• Finally open the SDFix folder on your desktop and copy and paste the contents of the results file Report.txt back onto the forum with a new HijackThis log

• Set Cookie Retention.
  Click on the Options block on the left, then choose Cookies.
  Under the Cookies to delete pane, highlight any cookies you would like to retain permanently (those companies or sites with which you regularly visit or do business), and click the right arrow > to move them to the Cookies to keep pane.

  Click on the Options block on the left. Select the Advanced button.
  Check "Only delete files in Windows Temp folders older than 48 hours".
  
  
  Now run the program and click on Run Cleaner

AVG Anti-Spyware:

This is not an ANTI VIRUS program but an anti spyware program . In case you were wondering.
________________________________________
Download the trial version of AVG Anti-Spyware from here and install it. When the program has been installed, and you click the Finish button, AVG Anti-Spyware will open. Do not run a scan yet.

If the program does not automatically update itself during installation, or you are unsure whether it has done so, please do the following:

• Click the Update icon at the top and under Manual Update click the Start update button.
• The program will either update or inform you that no update was available.
• It is essential that you get the update - keep trying until successful. (Note: If you have problems getting the update, you can download an installer for the full database from here (save it on your desktop). Once you have downloaded the installer, make sure that AVG Anti-Spyware is closed and then double-click on avgas-signatures-full-current.exe to install the database).
  
  
  
  Reboot your computer in Safe Mode.
• If the computer is running, shut down Windows, and then turn off the power.
• Wait 30 seconds, and then turn the computer on.
• Start tapping the F8 key. The Windows Advanced Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.
• Ensure that the Safe Mode option is selected.
• Press Enter. The computer then begins to start in Safe mode.
• Login on your usual account.
• Open up AVG anti Malware

Please set up the program as follows:

• Click the Shield icon at the top and under Resident shield is... click active. This should now change to inactive.
• Click the Update icon and untick the automatic update option.
• Click on Scanner on the toolbar.
• Click on the Settings tab.
  
• Under How to act? - make sure that Quarantine is selected.
• Under How to scan? - All checkboxes should be ticked.
• Under Possibly unwanted software - All checkboxes should be ticked.
• Under Reports - Select Do not automatically generate reports.
• Under What to scan? - Select Scan every file.

Close all open windows.

• Click on Scanner on the toolbar.
• Click on Complete System Scan to start the scan process.
• Let the program scan your computer.
• When the scan has finished, follow the instructions below:
• Make sure that Set all elements to: shows Quarantine
• Important: Click on the Apply all Actions button (*** This must done before saving the report ***)
• When the program has finished, it will display the message All actions have been applied.
• Then click the Save Scan Report button.
• Click the Save Report as button.
• Save the report to your Desktop.
• Right-click the AVG Tray Icon and select Exit.
  
• Reboot in normal mode.
