I think I am infected with mdm.exe virus. I cannot connect properly to the internet - get the "timed out couldn't connect to server etc.

When trying to open a new option, lets say in your forums, such as clicking on "am I infected" amongst others, the new tab opens but a message appears "Prefetching or precaching is not allowed"

My computer was fine earlier on in the day.l

I also can't get my emails from Outlook express.

Windows media player error : ffdshow error. reconnect failed - please restart video application.

So far, that's all I know as I don't want to continue any further incase of infecting any more.

Please help with this.

Oh, by the way, I am using my dial-up to connect.
Many thanks
Nat

Are you sure this is a bad file or asking if it is?

mdm.exe is Microsoft's Machine Debug Manager program that is installed with the Microsoft Script Editor (componet of Office XP/2000) to provide support for program debugging.

The Script Debugger is actually a JScript debugger used by programmers and advanced users when debugging programs; testing scripts developed using an ActiveX script engine; debug scripts developed with VBScript and JScript, ActiveX components and Java applets. It allows viewing and modifying program source code, variables, and values, or controlling the flow and pace of how the script works and allows debugging Internet Explorer errors by using a script interface tool.

This process starts when script debugging is enabled in Internet Explorer. It runs as a service with the local system account and is loaded when the computer starts. This is a non-essential process and if you do not use your computer for debugging purposes, you can safely turn off the Machine Debug Manager. See "How to turn off Machine Debug Manager in Office XP" and "How to Disable the Machine Debug Manager in Windows XP".

Note: If another application reinstalls Mdm.exe, or if Mdm.exe /Regserver is run on a computer that is running Window ME/XP, Mdm.exe is re-added to the RunServices registry key. Running the Detect and Repair feature within Office XP/2K causes Mdm.exe to be re-registered on the system.

mdm.exe could also be a process registered as a virus depending on the directory location it runs from. The path for the legit file is: C:\Program Files\Common Files\Microsoft Shared\VS7DEBUG\MDM.E.

Anytime you suspect a file to be malware, you can submit it to jotti's virusscan or virustotal.com.
In the "File to upload & scan" box, browse to the location of the suspicious file and submit [upload] it for scanning/analysis.
Then post back with the results of the file analysis.

No, I am not sure that this is a bad file, so I am asking. I feel that it is, otherwise what's the problem with connecting with LAN, email, prefeching not allowed etc, as mentioned in first post?


I know that mdm.exe is microsoft ( I researched before I posted!).

I would like to turn it off and I have looked at the Microsoft help on this and at Fredd's link.

The problem is, that for a few months or so, in the Advanced Tab, it does not allow any box to be checked or unchecked. Clicking on the box simply highlights the description.

Any ideas on how to fix this or perhaps another method / way of accessing the advanced options?

Then investigate the path where it is running from or submit to jotti and its scan will advise you.

Advanced Tab, it does not allow any box to be checked or unchecked

I accessed Run "services.msc" and was able to disable mdm from there. But still I have the same problems.

My apologies if my questions are ignorant, but how do I find the path where it is running from?

I have followed the microsoft help path for Advanced Tab ... and am still unable to check tab check boxes.

I am unsure on how to use the mpvs.org option. I have opened it, but don't w3ant to do anything in case of messing up!

What is interesting is that by using my dialup connection I am able to access outlook express and send & receive as well as accessing the internet (as you can see !). Why does my dialup perform fine and my LAN does not?

Do you think that my LAN connection is at fault? If it makes any difference, I live in Cape Town, South Africa. My ISP provider is Mweb. My ADSL is provided by Telkom ADSL Premium Combo - 802.11g ADSL 2/2+
I have run the setup CD for the above again,. but still no change.

Perhaps I should run HJT ? Please advise. Thanks.

...but how do I find the path where it is running from?

You can download and use Autoruns or Process Explorer to investigate all running processes and gather additional information to identify and resolve problems. This tool will show the process CPU useage, a description and its path.

I am unsure on how to use the mpvs.org option. I have opened it, but don't w3ant to do anything in case of messing up!

The mpvs option involves making changes in the registry. Always back up your registry before making any changes. If you are not familiar with working in the registry, then you should NOT attempt to make any changes on your own.

Click on the link below:
http://mvps.org/winhelp2002/RepairTabs.reg
Go to File, choose "Save page as" All Files and save RepairTabs.reg to your desktop. Double-click on the file and choose "Yes" to merge it into the registry when prompted.

If your still having problems after this, then go ahead and post a hijackthis log. Please read and follow all instructions in the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". You may have performed some of these steps already. About half way down are instructions for downloading HijackThis and creating a log.

When you have done that, post your log in the HijackThis Logs and Analysis Forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log here.

After posting a log you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc.) unless advised by a HJT Team member. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make may cause confusion for the member assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
