My laptop has the Trojan.Zeroaccess bug. I've read several threads and forums on this, but it seems that I need personal assistance and not just follow generic advice. I've downloaded most of the programs that I've read about (ComboFix, ERUNT, OTL). Now I just need help getting rid of this darn thing! Can someone walk me through?
THANKS!

THEN
Download and Install Combofix
Download ComboFix from one of the following locations:
Link 1 (http://download.bleepingcomputer.com/sUBs/ComboFix.exe)
Link 2 (http://www.forospyware.com/sUBs/ComboFix.exe)
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 (http://forums.whatthetech.com/How_Disable_your_Security_Programs_t96260.html&pid=494216#entry494216)

- 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

I disabled Symantec Endpoint but ComboFix insisted it was still enabled. Is there any way to determine if it ran properly? When my system rebooted, the Trojan.Zeroaccess warnings did NOT pop up.
-
No thats fine, any outstanding problems ?
-
Not that I've noticed. Thank you so much for your help!!!
-
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
(http://i1224.photobucket.com/albums/ee362/Essexboy3/Misc%20screen%20shots/CF_Uninstall-1.jpg)
- 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
- Go to control panel
- Select folder options (Appearance > Folder options in category view)
- 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 (http://www.malwarebytes.org/mbam-download.php). Update and run weekly to keep your system clean
Download and install FileHippo update checker (http://www.filehippo.com/updatechecker/) 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 (http://windowsupdate.microsoft.com)
