Hello,

 

May I ask what version of Symantec Endpoint Protection you have installed? There was an issue like this that is addressed in RU7 MP2. If you are running an older version, I recommend upgrading at your earlist convenience.

SEP 11 Release Notes - http://www.symantec.com/business/support/index?page=content&id=TECH103087&key=54619

 

In the future, it would be best to post SEP product issues in the Connect forums, as this is a consumer product (Norton) forum.

Please do not run any tools unless instructed to do so. 

  • We ask you to run different tools in a specific order to ensure the malware is completely removed from your machine, and running any additional tools may detect false positives, interfere with our tools, or cause unforeseen damage or system instability.

Please read every post completely before doing anything. 

  • Pay special attention to the NOTE: lines, these entries identify an individual issue or important step in the cleanup process.

 

  • Logs from malware removal programs (OTL is one of them) can take some time to analyze. I need you to be patient while I analyze any logs you post. Please remember, I am a volunteer, and I do have a life outside of these forum, (sometimes :smileylol:)

  • Attention to detail is important! Since I cannot see or directly interact with your computer I am dependent on you to "be my eyes" and provide as much information as you can regarding the current state of your computer.

 

Download OTL   hxxp://oldtimer.geekstogo.com/OTL.exe   (change the hxxp to http) save it to your Desktop.

Double click on OTL.exe to run it.  Right click OTL.exe and select run as administator for Vista and Win 7.

 

Disable Norton for say 30 minutes

 

Start OTL,  

Click the Scan All Users checkbox.

Change file age to 60 days

Re: Trojan.gen 2 80000000.@ removal help

You also have the services.exe variant of zeroaccess

Firstly we have take the first layer, the CLSID

 

Disable Norton for say 30 minutes

 

Start OTL,   under   Copy and paste the custom script attached which you open in for instance Notepad,(include the : at the start of :OTL and all the way to the end / bottom)  and run the script. (Red Run Fix Button)

 

The output log, should be placed in the C:\ _OTL folder after.

Re: Trojan.gen 2 80000000.@ removal help

You may find Symantec us now detecting the files in a different or now different files now that layer is broken, That is Ok

 

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.
  • Close any open browsers and any other programs you might have running

Doiwnload the attached CFscript.txt, , For some browsers Right Click the attachment on the forum and select "Save AS" or similar to Download it. See screenshot below.

 

Right Click download.jpg

 

Now  drag the CFScript.txt into the ComboFix.exe  

 


  • 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)
