Win32.ZAccess-PB removal, a few questions
« on: April 11, 2013, 12:00:34 PM »
Hello,

This morning (albeit could have been for a while as i didn't realise my avast had died and what not until i reinstalled), ive been getting constant popups from a Win32.ZAccess-PB virus, every 5-10 minutes or so. I'm running a full system scan and it's showing signs of a number of infected files (whoops).

Will this one get removed at the end of the scan, or is there more i need to do?

Kind regards,
Shane

Hey,

Should i wait for the current full scan on Avast to complete first? It's taking a long time. (10% in 1 hour, 7 infected files found so far)

OK lets kill it

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


Code: [Select]
:Files
C:\$Recycle.Bin\S-1-5-18
C:\Windows\assembly\GAC_32\Desktop.ini
C:\Windows\assembly\GAC_64\Desktop.ini

:Commands
[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

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:

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 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:
