Avast blocking google
« on: April 06, 2012, 11:19:27 PM »
Recently the computer was infected with the 2012 Internet Security malware and I have manually removed it to regain some access to the computer.
Avast boot-scan was used to clear out some infections.
Now most websites I visit to, Avast report that google-analytics/ga.js was blocked from being accessed.

Unable to attach log from the infected computer at the moment since I am unable to pass the verification image due to it being blocked.  I'm afraid about using a usb/mail to transfer the log to another computer.

Edit: title was edited since google is simply blocked and no redirection happened

On the Host computer and the usb drive run Panda Vaccinate and that should protect them both

OK Avast has now identified the infected file, but I will need to use a seperate programme to kill that

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

If you have Malwarebytes 1.6 or better installed please disable it for the duration of this run

Open the scanner and select the protection tab
Remove the tick from "Start with Windows"
Reboot and then run OTL


Run OTL
  • Under the Custom Scans/Fixes box at the bottom, paste in the following

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
  • Allow the installation of the recovery console




  • 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

anything from google is still blocked.  Other than that, the computer seem to run normally as before.

Avast seem to pick up on c_726564.nls as a Rloader-B again after a scan.

Everything seems to be working fine, avast no longer blocks google.
Avast full system scan seem to be picking up on C:\WINDOWS\system32\c_726564.nls as a Rloader-B.  Is it really a threat?
Nevermind, Avast can finally remove that file.  Thanks.

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
    Quote
    :Commands
    [resethosts]
    [emptytemp]
    [CLEARALLRESTOREPOINTS]
     [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.
   Your Java is out of date.
Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

 Upgrading Java:
  • Go to this site  and click Do I have Java
  • It will check your current version and then offer to update to the latest version
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 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:
