Viruses 000000cb.@ 80000032.@ 00000004.@ Win32:ZAccess Win32:Sifef

[stormtea]

Avast finds and blocks these infections every five minutes.
Performing a boot time scan and using malwarebytes did not resolve anything.
aswMBR.exe kept crashing at the same spot so I could not post that program's log file (I can post the screenshot).

All the logs are attached, please help.

The infections are:

000000cb.@

80000000.@

80000032.@

00000004.@

Win32:ZAccess-JC

Win32:Sirefef-ZT

Hi lets get you your computer back

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]

:OTL
[2012/10/16 19:25:22 | 000,004,608 | -HS- | M] () -- C:\Windows\assembly\GAC_32\Desktop.ini
[2012/10/16 19:25:22 | 000,006,144 | -HS- | M] () -- C:\Windows\assembly\GAC_64\Desktop.ini

:Files
C:\Windows\Installer\{8c307b11-acb2-b144-ce81-64b0fe8863cf}

: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

FINALLY

Download and run farbar service scanner



Tick "All" options.
Press "Scan".
It will create a log (FSS.txt) in the same directory the tool is run.

Please copy and paste the log to your reply.

I'm sorry for the delay, I have attached the three log files.
The computer is running fine, Avast isn't picking up on anything.
Thank you very much for your help.

[essexboy]

Looks like we got it in one sweep 

How is the computer behaving now ?

[stormtea]

Everything runs perfectly!
It seems everything is good, performance and behavior wise.
A quick scan with MBAM shows nothing and the computer rebooted without problem multiple times. Avast hasn't found anything either.

Is there anything left to do?

Thank you very very much for you help.

[essexboy]

Just this ......

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
  

  :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

• Click Start.
• Open My Computer.
• Select the Tools menu and click Folder Options.
• 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.

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

• 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:

[stormtea]

Ok, done.
As you suggested, I will observe closely how the computer behaves for a day or two.

Again, thank you so, so much for your time and help.
You were so quick and efficient, I almost feel sorry for the virus. ^{_{(No I don't)}}
