Hey guys. I noticed my computer running slow lately - and decided to do a full scan.

I cant read the full lines since my avast crashes cause it have to block the trojan house more than twice pr. minute.

I cannot get the file deleted??

So far i can get this information out of avast

Object C:.…\2F4973b5-0000002f8.eml:OECUSTOM

Infection: Win32:BitCoinMiner-AH [Trj]

Action: Move to quarantine

Proces: C:.…\SearchProtocolHost.exe

Would be grateful for some help - thanks in advance

Follow this guide: http://forum.avast.com/index.php?topic=53253.0

and attach ( Do not copy/paste ) logs for AdwCleaner, malwarebytes’, OTL, and aswMBR.exe

An expert in the removal of malware will help you.

I reattached the logs - for all except from the aswmbr. aswmbr keeps crashing, i tried running it normaly, running it as administrator and running it in safe mode. Everytime it crashes before it completes the scan?

This looks like a new variant

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.

[*]When finished, it shall produce a log for you.
[*]Please include the C:\ComboFix.txt in your next reply.

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

Hey - thank you for answering

The log is now attached.

I dont get all the pop-ups from the avast anymore - should i do another full-scan or?

6

If you could now run a quick MBAM scan please and let me know how the system is running

7

What should i tell about how the computers running? i think it is a bit better than before, and i dont have as high CPU spikes?

MBAM is attached

OK that looks good, it seems as though this new variant works just from an ADS, which will make it easier to remove. If all is well tomorrow let me know and I will tidy up :slight_smile:

9

Cool - i make a new post tomorrow then.

Thank you for the useful advice on removing. have a great day

10

I think the computer is running better now… only been playing a little bit of poker, but it does not take nearly as long to open the windows now.

thank you

Subject to no further problems :slight_smile:

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:

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.

Clear Restore Points

Go Start > All Programmes > Accessories > System tools
Right click Disc Cleanup and select run as administrator
When it pops up at the first prompt select OK after it has done some calculations the tabs will appear
Select More Options tab
Press Sytem Restore and Shadow Copies Cleanup button

: Keep Java Updated :

WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article and this article.
I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser and How to unplug Java from the browser)

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

If you use on-line banking then as an added layer of protection install Trusteer Rapport

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
[*]Microsoft Windows Update

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:
