Hi and thanks for your time. I know all of you work your @sses off for free to help others; so b4 I start, thank you in advance. My main PC (haven't been using it often w/ a new laptop) is giving me an error on boot "An unauthorized change was made to Windows" and pretty much blocks me from finishing the boot, throwing me back to user login window. In another thread, I posted the MS Genuine Advantage Diag Tool report, and someone advised that I may have malware; in the form of "In Memory Mod-Auth Tamper"?

Seems many people were having issues with Avast security during an upgrade that caused a conflict w/ MS Genuine, and some people simply removed Avast both through control panel + using Avast's removal tool in safe mode. I have done this. Technically I have not had a problem since just yet, but I haven't spent much time on the machine accept running some diag. I purchased and installed MalwareBytes and am running a full system scan now; it'll prob take a bit longer, easily an hour or two more. I also ran a HijackThis report, and I have the log file, I'll past it below.

To be clear, my issue seemed intermittent on boot; and then oddly let me into my desktop like it was no problem. I'm posting here in this forum because I am concerned that Avast conflict or not, there is a deeper issue perhaps and I'd really appreciate help evaluating what's up w/ the system. Thanks for your time.

Hello and welcome to Bleeping Computer!

I am HelpBot: an automated program designed to help the Bleeping Computer Staff better assist you!

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

To help Bleeping Computer better assist you please perform the following steps:


First, I need to know if you still need help! To tell me this, please click on http://www.bleepingcomputer.com/logreply/409861 and follow the instructions there. If you no longer need help, this is all you need to do. If you do need help please continue below.


If you still need help, I would like you to post a Reply to this topic (click the "Add Reply" button in the lower right hand of this page). In that reply, please include the following information:

  • If you have not done so already, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • A new DDS and GMER log. For your convenience, you will find the instructions for generating these logs repeated at the bottom of this post.
    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.
    • If you are unable to create a log please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and we will guide you.
  • Please tell us if you have your original Windows CD/DVD available.
  • Upon completing the above steps and posting a reply, another staff member will review your topic and do their best to resolve your issues.

Thank you for your patience, and again sorry for the delay.


We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE

We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice

Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log

As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!
