Win32:Malware-gen (services.exe) pop ups
« on: July 07, 2012, 05:06:41 AM »
Hi, so I recently got nudged with this consistent malware blocked notice..

It started this morning.. left my computer on while at work, got 300 or so hits from my file system shields.

C:\Windows\Installer\...\80000000.@ (I think that's the correct amount of 0s...)
C:\Windows\Installer\...\800000cb.@

are the two objects that are being blocked and the process being : C:\Windows\System32\services.exe

at the start of this, my log says I got nudge by two other unique ones to those two however.

C:\Users\[MyUserProfile]\AppData\Local\....\n
&
C:\Windows\Installer\...\n

from then on it's just been those two consistent pop up alerts.

Help?  :'(

Yep I have cured systems with Avast through to Zone Alarm and all points between, none are able to stop this .. Yet

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

Run OTL
  • Under the Custom Scans/Fixes box at the bottom, paste in the following


    Quote
    :OTL
    O3 - HKU\S-1-5-21-3690343684-71013159-3065316002-1001\..\Toolbar\WebBrowser: (no name) - {21FA44EF-376D-4D53-9B0F-8A89D3229068} - No CLSID value found.

    :Files
    C:\Windows\Installer\{e20e494d-3964-d885-9700-bc0b1763a147}
    C:\Users\Djansen\AppData\Local\{e20e494d-3964-d885-9700-bc0b1763a147}

    :Commands
    [purity]
    [resethosts]
    [emptytemp]
    [CREATERESTOREPOINT]
    [Reboot]
  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done
  • Open OTL again and click the Quick Scan button. Post the log it produces in your next reply.
THEN

Download and Install Combofix
 
Download ComboFix from one of the following locations:
Link 1
Link 2
 
VERY IMPORTANT !!! Save ComboFix.exe to your Desktop
 
* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
  • Double click on ComboFix.exe & follow the prompts.
  • Accept the disclaimer and allow to update if it asks




  • When finished, it shall produce a log for you.
  • Please include the C:\ComboFix.txt in your next reply.[/b]
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.
3.  If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.



Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

Win32:Malware-gen infected - need help!
« Reply #3 on: July 08, 2012, 01:20:31 AM »
I too am having problems with Win32:malware - gen.  I noticed my PC slowing down noticeably while browsing and the hard drive firing far longer and consistently than usual.  I ran Avast and MalwareBytes, neither detected anything.  Then ran Avast in boot scan and it found several instances of Win32:malware-gen.  It could not be moved to the chest, deleted or repaired.  I tried running both in Safe Mode and it also did not pick up anything.

Can you assist in getting rid of this very hard to kill thing?  I have already downloaded Combofix and have it on my desktop.  Thanks for any help you can provide.

Hi sorry for the late response, I had to sleep and go to work.. you know..

anywho.

I finish running the fix, rebooted. ran a quickscan, and downloaded combofix to my desktop.

Now I want to point out two things. One : I went to turn off windows firewall.. but I would only get a  "use recommended settings" button no matter where I navigated in the control panel for it. I left it alone assuming it wasn't on.
Two: I disabled Avast as your link specified. I ran Combofix and got a message saying that avast anti-virus was still active. I didn't really know what else to do though. I continued with the process.

Since then I restarted my computer, and it's running smoothly with no malware alerts from avast. I'm uploading the logs.

Subject to no further problems   :)

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Run OTL
  • Under the Custom Scans/Fixes box at the bottom, paste in the following
    Quote
    :Commands
    [resethosts]
    [emptytemp]
    [Reboot]
  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done
Remove ComboFix

  • Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
  • In the Run box, type in ComboFix /Uninstall (Notice the space between the "x" and "/") then click OK



  • Follow the prompts on the screen
  • A message should appear confirming that ComboFix was uninstalled
Run OTL and hit the cleanup button.  It will remove all the programmes we have used plus itself. 

We will now confirm that your hidden files are set to that, as some of the tools I use will change that
  • Go to control panel
  • Select folder options (Appearance > Folder options in category view)
  • Select the View Tab.
  • Under the Hidden files and folders heading select Do not show hidden files and folders.
  • Click Yes to confirm.
  • Click OK.

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

 Upgrading Java:
  • Go to this site  and click Do I have Java
  • It will check your current version and then offer to update to the latest version
SPRING CLEAN

To manually create a new Restore Point
 
  • Go to Control Panel and select System
  • Select System
  • On the left select System Protection and accept the warning if you get one
  • Select System Protection Tab
  • Select Create at the bottom
  • Type in a name i.e. Clean
  • Select Create
Now we can purge the infected ones
  • GoStart > All programs > Accessories > system tools
  • Right click Disc cleanup and select run as administrator
  • Select Your main drive and accept the warning if you get one
  • For a few moments the system will make some calculations
  • Select the More Options tab
  • In the System Restore and Shadow Backups select Clean up
  • Select Delete on the pop up
  • Select OK
  • Select Delete
Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes.  Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit
To learn more about how to protect yourself while on the internet read our little guide  How did I get infected in the first place ?

Keep safe  :wave:

Thank you very much for all your help.

One thing though.. When I bring up my "Run" and type in "Combofix /Uninstall" It brings up the disclaimer prompt saying I should disable my anti-virus as if it wanted to scan again.
Is that the prompt I'm suppose to receive? I cancel it since I don't want it to scan again.

Aside from that, I updated my Java, Already had Malwarebytes, windows updates shows everything is good. Also created a restore point as you said.

Just wondering on that Combofix worry.

Thank again.

This can happen if there is no space prior to /uninstall

In the Run box, type in ComboFix /Uninstall (Notice the space between the "x" and "/") then click OK
