Hello.

let's see what we can do.

Could you run Combofix for me first.

Download and Run ComboFix

Note to readers of this post other than the starter of this thread:
ComboFix is a VERY POWERFUL tool which should NOT BE USED without guidance of an expert.

Download Combofix from any of the links below, and save it to your desktop.
Link 1
Link 2

Please refer to this page for full instructions on how to run ComboFix.
  • Close/disable all anti-virus and anti-malware programs so they do not interfere with the running of ComboFix. Refer to this page if you are not sure how.
  • Double click ComboFix.exe to start the program. Agree to the prompts.
  • When ComboFix is finished, a log report (C:\ComboFix.txt) will open. Post back with it.
Leave your computer alone while ComboFix is running.

ComboFix will restart your computer if malware is found; allow it to do so.


Note: Please Do NOT mouseclick combofix's window while its running because it may call it to stall.

Note: Please do not PM me asking for help, instead please post it in the correct forum requesting for help. Help requests via the PM system will be ignored.

If I'm helping you and I don't reply within 48 hours please feel free to send me a PM.

Sorry about that. Could you run OTL again as mentioned in my previous post so I can take another look.

I ran the OTL program and extra report wasn't there. The result is attached is OTL.txt. I then ran Avg manual scan, not the rootkit scan, and removed 10 hidden files. Last time it was only 6 or 7 hidden files. The avg rootkit scan does not find anything. I rebooted the server and then ran the OTL program again with the results in the attached file OTLa.txt. I have also taken a snapshot of the avg screen with the hidden files.

Can you post the full screen of AVG where it detected those, so I can see the exact location of it.

Run Malwarebytes for me...
Download and run MalwareBytes Anti-Malware

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
  • Make sure you are connected to the Internet.
  • Double-click on Download_mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
  • MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue. If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
  • On the Scanner tab:
    • Make sure the "Perform Quick Scan" option is selected.
    • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
  • Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad and you may be prompted to restart your computer. (see Note below)
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

For complete or visual instructions on installing and running Malwarebytes Anti-Malware please read this link


Note: Please do not PM me asking for help, instead please post it in the correct forum requesting for help. Help requests via the PM system will be ignored.

Those may be False-positives but, let's make sure. First run an online scan so we can take another look.

Run ESET Online Scan
  1. Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  2. Click the button.
  3. For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    1. Click on to download the ESET Smart Installer. Save it to your desktop.
    2. Double click on the icon on your desktop.
  4. Check
  5. Click the button.
  6. Accept any security warnings from your browser.
  7. Check
  8. Push the Start button.
  9. ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  10. When the scan completes, push
  11. Push , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  12. Push the button.
  13. Push
You can refer to this animation by neomage if needed.

Take a new DDS run afterward and post back with both the DDS and Attach logs in your next reply. Also, let me know how your computer is running and if you have any more problems, issues or symptoms left.

Thanks.

With Regards,
Extremeboy

I have just ran the ESETScan and attached the results. I did not have it removed, should I have, I didn't see that in your instructions and if it was a false positive I didn't want to remove it.

Regarding the DDS, I am running Windows Server 2003 and it would not run. Do you have a program that I should run?

You can go ahead and remove that.

Submit file sample
Could you then browse and upload some of those files your AVG detected so I can take a look.

Also, scan a few of them using an online scanner...

Open VirusTotal Online Scanner or VirSCAN. If one site is busy or down, try the other

Then run OTL...

Download and run OTL
  1. Download OTL by OldTimer and save it to your desktop.
  2. Double click on the icon on your desktop. If you are using Vista, please right-click and select run as administrator
  3. Click the "Scan All Users" checkbox.
  4. Push the button.
  5. It will now begin to scan, please be paitent while it scans.
  6. Two reports will open once it's done.
  7. Please copy and paste them in your next reply:
    • OTL.txt <-- Will be opened
    • Extras.txt <-- Will be minimized


Note: Please do not PM me asking for help, instead please post it in the correct forum requesting for help. Help requests via the PM system will be ignored.
