Trojan.patchep!sys will not go away

Shihosa · ‎07-13-2012

3 days ago I was scanning my computer with Norton anti-virus and Malwarebytes. Both programs found a few trojans (gen.2 and a few others) and per following the directions I cleaned those out and re-ran both programs to be sure it was cleaned.

On the second run they both found Trojan.patchep!sys and again I had the programs do what they could to clean it. Ran the programs a 3rd time and they both said the computer was clean and did not detect the Trojan.patchep!sys. Since then I have run Norton Anti-Virus and Malwarebytes every night and last night they found the Trojan.patchep!sys again. Please help me get rid of this bug permanently!

I have Windows 7 Professional 64-bit.

Yes I have a flash drive

I have downloaded the 64 bit version from http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/ onto the flash drive.

I did not proceed any farther as that could interfere with further instructions.

Please let me know what I can do next. Thank you for your time and help.

Welcome,

Sorry we are meeting under these circumstances. Please do not do anything in the way of self-help fixes. Wait for volunteer, user Quads to respond. He stays very busy so it will be a while. Follow his instructions exactly and you will have a clean machine when he finishes.

Keep us posted

ANY other user other than the thread starter is not to use any instructions, scripts or proceedures, The work though in cleaning a system is individual and only for that system due to a number of factors.

Please do not run any tools unless instructed to do so.

We ask you to run different tools in a specific order to ensure the malware is completely removed from your machine, and running any additional tools may detect false positives, interfere with our tools, or cause unforeseen damage or system instability. Do as the instructions ask nothing extra or run things twice
If I ask a Question just answer it, don't run anything unless it states.
Major steps used:

1. Find

2. Break

3. Destroy

4. Cleanup (including system as a whole)

Please read every post completely before doing anything.

Pay special attention to the NOTE: lines, these entries identify an individual issue or important step in the cleanup process.

Logs from malware removal programs (OTL is one of them) can take some time to analyze. I need you to be patient while I analyze any logs you post. Please remember, I am a volunteer, and I do have a life outside of these forum, (sometimes )
Attention to detail is important! Since I cannot see or directly interact with your computer I am dependent on you to "be my eyes" and provide as much information as you can regarding the current state of your computer.

Hello Quads,

I have followed your instructions and attached the file you requested.

Quads · ‎07-21-2008

You have run it twice, I did not ask you to do so. where is the log for run 1.

Users, there is No point asking for help, when you are going out of your own without instruction, or doing extra which I did NOT tell you to do.

Shihosa · ‎07-13-2012

Hello Quads,

That is the only log that is on the flash drive. During the original scan my computer crashed and when it came back up I followed the same instructions. I'm sorry I did not realize that it even made a first copy.

Step 3.

Please read carefully Read all of this message first

Download Combofix http://www.bleepingcomputer.com/download/anti-virus/combofix

Ensure that Combofix is saved directly to the Desktop <--- Very important (Not in the Download(s) or Temp folders)
Disable all security programs as they will have a negative effect on Combofix, Disabled for say 1 hour or more.
Close any open browsers and any other programs you might have running

Right click the combofix.exe on the desktop and select from the menu "Run as Administrator"

If you are using windows XP It might display a pop up saying that "Recovery console is not installed, do you want to install?" Please select yes & let it download the files it needs to do this. Once the recovery console is installed Combofix will then offer to scan for malware. Select continue or yes.
When finished, it will produce a report for you. Please post the "C:\ComboFix.txt" for further review

****Note: Do not mouseclick combofix's window while it's running. That may cause it to stall or freeze ****

Note: ComboFix may reset a number of Internet Explorer's settings, including making it the default browser.
Note: Combofix prevents autorun of ALL CDs, floppies and USB devices to assist with malware removal & increase security.

*EXTRA NOTES*

If Combofix detects any Rootkit/Bootkit activity on your system it will give a warning and prompt for a reboot, you must allow it to do so.
If Combofix reboot's due to a rootkit, the screen may stay black for several minutes on reboot, this is normal
If after running Combofix you receive any type of warning message about registry key's being listed for deletion when trying to open certain items, reboot the system and this will fix the issue (Those items will not be deleted)

Hello Quads,

I was doing as you requested when combofix popped up with a warning saying AVG internet security was still active and to shut it off. I removed AVG through the unistall on the control panel before I even downloaded Norton and started all this. It is asking if I wish to still run combo fix, should I continue or is there a different step you wish me to take?

Thank you
