Laptop infected, multiple dllhost.exe *32 COM Surrogate processes running.


Recommended Posts

Hello, 

 

I have a laptop that is infected. There are multiple dllhost.exe *32 COM Surrogate processes running. Currently the laptop is disconnected from the internet. As soon as I connect the laptop to internet I will start getting warning messages from my antivirus (ESET NOD32 Antivirus) that a "Address has been blocked", I don't have the web browsers open when these messages pop up. I assume the dllhost.exe processes running in the background are trying to connect to IP addresses. 

 

The IP addresses I've logged from those warnings are 95.215.1.57 and 195.2.240.79. 

 

Please I would appreciate any help on how to disinfect my laptop from these background processes. 

 

Thanks!

  • Close any open browsers and any other programs you might have running

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

*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)

Attached are the logs from MalwareBytes Anti-Rootkit and ComboFix. I ran MBAR twice. The first time I ran it, it found a one threat and clicked Cleanup. It rebooted my computer and then I ran it a second a time and the scan results came up cleanup, but I looked at Task Manager's Processes tab and it still showed the multiple dllhost.exe processess running. Later I ran ComboFix and I followed the instructions in the links that you provided. It rebooted my computer one time. 

 

Please let me know what are the following steps.

ComboFix.txt

mbar-log-2014-11-10 (09-40-37).txt

mbar-log-2014-11-10 (10-08-46).txt

system-log.txt

Download Farbar Recovery Scan Tool and save it to your desktop.

 

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.


Double-click to run it. When the tool opens click Yes to disclaimer.
Press Scan button.
It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

 

Let me see those two logs....

 

Thanks,

 

Kevin

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into.

NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

 

Run FRST and press the Fix button just once and wait.

When the scan is complete, if there have been detections, click Apply Actions to allow MBAM to clean what was detected.

Wait for the prompt to restart the computer to appear, then click on Yes.

 

 

Once completed please click on the History > Application Logs and find your scan log and open it and then click on the "copy to clipboard" button and post back the results on your next reply.
