svchost.exe Infected

[AllyLane]

Hi guys,

I am currently assisting my Dad with cleaning his computer. It is recurrently going to blue screen, ISP software won't load or suddenly stops, IE continually freezes, and there are dozens and dozens of copies of svchost.exe running which result in using over 60% of memory, even without any processes or programs loaded. Also DWM processes do not add up to the amount of private resource in use.

Plug and play drivers also disappear intermittently, which is why I am suspicious.

I had the same trouble on my own laptop and recently had to resort to a complete reinstall of the OS. Hoping to get out of that here.

Logs attached as clipboard will just not cope and results in blue screen every time. I would really appreciate your help please!

OK cool. Could you please leave this thread open for me. My Dad is returning to his home town and I will recommence assistance for his computer remotely. This will happen within 48 hours. Thanks!

[CatByte]

ok, no problem

[CatByte]

do you still need help with your machine?

[AllyLane]

Yes please! I have just been in touch with my Dad today and have organised a remote session in a couple of hours' time. Following that I will post some more scan results.

Thanks so much for keeping this open!

[AllyLane]

After some trouble connecting remotely, we have managed to run both scans. Logs attached.

Malwarebytes detected Trojan.Agent. Cleaned up after first scan, then rebooted. Ran second time and detected the same trojan.

I read elsewhere (this forum) that a reboot will reanimate this particular virus. Following second MWB scan we did not reboot.

I am purchasing MWB Pro for my computer - will having that on this machine assist with a clean reboot?

Ran ESET scanner. Found 6 threats, of which 3 were cleaned. Program was closed without deleting quarantined files.

So, at this point, the computer has been left on without restarting after either of the above 2 scans.

Thanks heaps

my apologies for the late reply

please delete the copy of ComboFix that you have on your desktop and download a fresh copy from the link below:

now please do the following:

• Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before following the steps below.
  
• They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
  

Copy/paste the text inside the Codebox below into notepad:

Here's how to do that:

Press the WinKey + R to open a run box, type Notepad > click OK.

This will open an empty notepad file:

Copy all the text inside of the code box - Press Ctrl+C (or right click on the highlighted section and choose 'copy')

C:\ProgramData\ejxfg.exe

C:\ProgramData\rixdw.exe	
C:\Users\Pfeiffer\AppData\Local\Temp\cscomp.dll

ClearJavaCache::

Now paste the copied text into the open notepad - press CTRL+V (or right click and choose 'paste')

Save this file to your desktop, Save this as "CFScript"

Here's how to do that:

1.Click File;

2.Click Save As... Change the directory to your desktop;

3.Change the Save as type to "All Files";

4.Type in the file name: CFScript

5.Click Save ...

• Referring to the screenshot above, drag CFScript.txt into ComboFix.exe.
  
• ComboFix may request an update; please allow it.
  
• ComboFix will now run a scan on your system. It may reboot your system when it finishes. This is normal.
  
• When finished, it shall produce a log for you.
  
• Copy and paste the contents of the log in your next reply.
  

CAUTION: Do not mouse-click ComboFix's window while it is running. That may cause it to stall.

When CF finishes running, the ComboFix log will open along with a message box--do not be alarmed. With the above script, ComboFix will capture files to submit for analysis.

• Ensure you are connected to the internet and click OK on the message box.

[AllyLane]

Thanks heaps for getting back to me! It's really no problem, I know how busy you must be and we appreciate you having kept this thread open for us.

The log is attached. Unfortunately I cannot copy and paste contents directly into post as this causes Blue Screen when large amounts are copied to clipboard.

Cheers
