HELP!!! C:\windows\system32\services.exe is infected

My boss brought me his laptop and told me it has a virus.  We use Symantec Endpoint Protection.  I logged into the system and did a full scan.  All but one issue got fixed. 

The C:\windows\system32\services.exe is infected with trojan.patchep!sys.  I'm new to this post/forum and don't know what to do next.  Please advise as soon as you can.

Re: HELP!!! C:\windows\system32\services.exe is infected

Hello KStice

Welcome to the Norton Community

Please don't do anything further while waiting for Quads who is our volunteer expert malware removal person. As you can see he is helping many others. He will want to know most likely what operating system and if it is 32 bit or 64 bit. He will probably ask you if you have a flash drive. If you give him these answers, it will help him to get a start with you. He is most likely in a different time zone than you are in, so there may be a little wait for him to respond also. Please don't try and do what he has recommended to others to do as each case is different. Thanks.

Success always occurs in private and failure in full view.

Re: HELP!!! C:\windows\system32\services.exe is infected

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.

Read Slowly and all of it.

Please download http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/   You need to download the 64 bit version 

Transfer it on to the Flash Drive / portable Hard Drive.

Enter System Recovery Options

To enter System Recovery Options from the Advanced Boot Options:

  • Restart the computer.
  • As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.
  • Use the arrow keys to select the Repair your computer menu item.
  • Choose your language settings, and then click Next.
  • Select the operating system you want to repair, and then click Next.
  • Select your user account and click Next.


On the System Recovery Options menu you will get the following options:

Startup Repair
System Restore
Windows Complete PC Restore
Windows Memory Diagnostic Tool
Command Prompt


  • Select Command Prompt
  • In the command window type in notepad and press Enter.
  • The notepad opens. Under File menu select Open.
  • Select "Computer" and find your flash drive  / portable Hard Drive letter and close the notepad.
  • In the command window type e:\frst.exe (for x64 bit version type e:\frst64) and press Enter
    Note: Replace letter e with the drive letter of your flash drive.
  • The tool will start to run.
  • When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (FRST.txt) on the flash drive.  restart the system and load Windows Please attach the log in your reply.

Step 3. 

Please read carefully Read all of this message first

Download Combofix http://www.bleepingcomputer.com/download/anti-virus/combofix  It will be a new copy as it always gets updated.


  • 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)

No the person did it with purpose, one of those afternoons

step 4. (a)

Please read carefully and Slowly

 Please scan with ESET next 


I'd like us to scan your machine with ESET OnlineScan

  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the  button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on  to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the  icon on your desktop.
  • Check 
  • Click the  button.
  • Accept any security warnings from your browser.
  • Under scan settings, check  and DON'T (NO) check Remove found threats (reason for this is we don't want something deleted and then Windows won't load).
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • Attach the resulting log in your next reply


If you think a log should have been generated then go to C:\Program Files\ESET\ESET Online Scanner\log.txt to find it.

Looks like that did it!  Thanks!  Have a great night/day (where ever you are located).

Re: HELP!!! C:\windows\system32\services.exe is infected

Disable Norton

Start OTL again but this time click the Black CleanUp button, then make sure the C:\_OTL folder is deleted.

After that you are free to go on your merry way.  You are now fixed / Solved.

If you want Malwarebytes download the Free version to install and don't click the Trial button

If you want to, you can turn off System Restore wait for it to clear the Restore Points and then Turn it back on once you find all is happy. today, tomorrow whenever.
