When I run Norton AV 2007, I can see the file names and paths of several pieces of malware. However, I can't navigate to them in Windows Explorer, and Malwarebytes Anti-Malware and Ad-Aware can't pick them up at all. Processes don't show up in Pocket Killbox or Task Manager either. This is on a WinXP home SP2 machine, if that makes a difference.

Welcome to BC ChevelleC8

What OS (Win 2K, XPsp1, XPsp2, Vista) are you using? Have you tried doing your anti-virus scan in "Safe Mode"?

What are the specific file names associated with this malware threat and where are they located (full file path) at on your system?

It is a Windows XP machine. I have tried running Norton in Safe Mode. It shows file paths across the top of the scan window, yet it doesn't view these as a threat. I've tried having it scan system folders and have all hidden files shown, but that doesn't seem to help either. Here are some paths it shows as it scans. There are a few additional ones as well.

C:\Documents and Settings\HP_Owner\Desktop\AntivirusGolden 3.7 lnk
C:\Program Files\Deus Cleaner\SDmodul.dll
C:\Program Files\Ardamax Keylogger\AKL.exe
C:\Program Files\ezurl\ epnt.sys

There are also some registry keys and entries related to these that it shows as well. However, the scanner says it finds no threats at all. Windows Explorer and MBAM don't see the files, even with all hidden and system files showing while in safe mode. Regedit doesn't see the related keys or entries either. I keep all security programs and the OS updated regularly, so I don't know why it's acting like this.

Go to jotti's virusscan or virustotal.com. In the "File to upload & scan" box, click the "browse" button and locate the following file:
C:\Program Files\ezurl\epnt.sys <- this file
Click "Open", then click the "Submit" button.
-- Post back with the results of the file analysis in your next reply.

Keylogging programs can be legitimate but their related files are often detected by anti-virus or anti-malware scans as a "RiskTool", "Hacking tool, "Potentially unwanted tool" or even a "Trojan". These types of programs have legitimate uses in contexts where an authorized user or administrator has knowingly installed it. Potentially unwanted does not necessarily mean the file is malware or a bad program. It means it has the potential for being misused by others. Anti-virus and anti-malware utilities cannot cannot distinguish between "good" and "malicious" use of such programs, therefore they may alert the user.

If you did not install this program, is it possible that another member of your family installed it?

If no one claims responsibility for installing the software, you should consider the computer compromised. If it was used for online banking or has credit card information on it, all passwords should be changed immediately to include those used for email, eBay and forums. They should be changed by using a different computer and not the one where the keylogger was installed. Because your computer was compromised please read How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Many experts in the security community believe that once infected with this type of malware, the best course of action is to reformat and reinstall the OS. Please read "When should I re-format? How should I reinstall?"

MBAM should have detected/removed some of those entries. Did you run it in normal mode or safe mode. MBAM is designed to be at full power when malware is running so safe mode is not necessary when using it. In fact it loses some effectiveness for detection & removal when used in safe mode.

I uploaded epnt.sys to jotti's virusscan and got this analysis:

The file you uploaded is 0 bytes. It is very likely a firewall or a piece of malware is prohibiting you from uploading this file

I disabled my outbound firewall and tried it again, but got the same result. I've tried it with other files like sdmodul.dll and get the same result too. As for the keylogger, nobody else claims to have installed it, so I changed all passwords to forums, email, etc. According to jotti's virusscan and MBAM, none of these files exist. I've been running MBAM in normal mode.

This issue will require further investigation and probably the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a hijackthis log.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log" and complete all the steps. There are instructions for downloading and running Deckard's System Scanner (DSS) which will create a hijackthis log for you, or automatically download and install the most current version of HijackThis if it's not already installed on your computer.

When you have done that, post your log in the HijackThis Logs and Malware Removal 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. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

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 "bump" your post or 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.
