Re: Trojan.Zeroaccess & Backdoor. Trogan

Step 3.

 

Please read carefully Read all of this message first

 

Download Combofix http://www.bleepingcomputer.com/download/anti-virus/combofix


  • Ensure that Combofix is saved directly to the Desktop <--- Very important

  • Disable all security programs as they will have a negative effect on Combofix, Disabled for say 1 hour or more.
  • Close any open browsers and any other programs you might have running

Right click the combofix.exe on the desktop and select from the menu "Run as Administrator"

 

  • If you are using windows XP It might display a pop up saying that "Recovery console is not installed, do you want to install?" Please select yes & let it download the files it needs to do this. Once the recovery console is installed Combofix will then offer to scan for malware. Select continue or yes.
  • When finished, it will produce a report for you. Please post the "C:\ComboFix.txt" for further review


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

Note: ComboFix may reset a number of Internet Explorer's settings, including making it the default browser.
Note: Combofix prevents autorun of ALL CDs, floppies and USB devices to assist with malware removal & increase security.

*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)

Re: Trojan.Zeroaccess & Backdoor. Trogan

Quads,

 

              I'm just double checking,I see on the instuctions I'm to disable Norton, When I do this should I disconnect from the internet? The reason I ask is that since I first started in this forum Norton has blocked the two Trojans over 50 times.

Some of the CLSID zeroaccess variants as a symptom,  whether broken or not can cause Windows to go into a reboot ever 1 minute.

Quads,

 

It took 7.5 hours for Combofix to run, when it started it said that Norton 360 was up and running but it wasn't, I had disabled it. Matter fact I disabled it till it restarted since it was taking so long.

Quads,

 

I thought I'd also add that since the ComboFix was ran there hasn't been any more Trojan alerts through Norton.

Re: Trojan.Zeroaccess & Backdoor. Trogan

I am trying to decide due to the fact it took 7.5 hours whether to run a script for the registry using a new combofix download, but use it in Safe Mode.

 

services.exe has been cured.

Re: Trojan.Zeroaccess & Backdoor. Trogan

I'll wait on your decision, I know you know what your doing. I can run ComboFix again if needed. Why do you think ComboFix was saying that Norton was enabled when it wasn't?

Re: Trojan.Zeroaccess & Backdoor. Trogan

It could be that one of the protections in Norton is not turned off or the Windows security centre is mis reporting.

 

I think we will go on to step 4.

 

Please read carefully and Slowly

 

 Please scan with ESET next 


I'd like us to scan your machine with ESET OnlineScan

  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Posted Image to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Under scan settings, check Posted Image and DON'T (NO) check Remove found threats (reason for this is we don't want something deleted and then Windows won't load).
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • Attach the resulting log in your next reply


If you think a log should have been generated then go to C:\Program Files\ESET\ESET Online Scanner\log.txt to find it.

Re: Trojan.Zeroaccess & Backdoor. Trogan

Just so you can see,   this is the flip of what you are doing and is real dumb to do,http://community.norton.com/t5/Norton-360/Trojan-Zeroaccess-amp-Backdoor-Trojan/td-p/744424

 

The guy has extras to deal with and cleanup to handle.
