Removing exploit:win32/cve-2011-0096 AND Win32/Pdfjsc.FP

Recommended Posts

Okay guys, first of all thanks in advance for the assistance. Recentely took over a new network(two actually) and I'm in the process of cleaning up the mess from the previous administrator. No security updates had been applied in over a year, if all to most all of the servers. At any rate, I have a 2003 Server machine that's bugged out on me(Which happens to be my machine that they have POP3 running over (no Exchange :( and my Backup Exec software. Installed M$ Security Essenitals and it keeps giving me the following items detected: 



and a few instances of



I need to get these off this box with as little damage as possible. to rebuild what's on here, lets just say i'd be at a loss as there's no prior documentation. I understand from what I've read these are both two nasty ass Trojans' with rootkits. I've fully updated the server now, however, these obviously keep coming back.

Hi there,
my name is Marius and I will assist you with your malware related problems.

Before we move on, please read the following points carefully.

  • First, read my instructions completely. If there is anything that you do not understand kindly ask before proceeding.
  • Perform everything in the correct order. Sometimes one step requires the previous one.
  • If you have any problems while following my instructions, Stop there and tell me the exact nature of your problem.
  • Do not run any other scans without instruction or add/remove software unless I tell you to do so. This would change the output of our tools and could be confusing for me.
  • Post all logfiles as a reply rather than as an attachment unless I specifically ask you. If you can not post all logfiles in one reply, feel free to use more posts.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.
  • Stay with me. I will give you some advice about prevention after the cleanup process. Absence of symptoms does not always mean the computer is clean.
  • My first language is not english. So please do not use slang or idioms. It could be hard for me to read. Thanks for your understanding.

    [*]Leave everything else as it is. [*]Close all other running programs as well as your Browser. [*]Click the Scan button & wait for it to finish. [*]Once done click on the Save.. button, and in the File name area, type in "ark.txt" or it will save as a .log file which cannot be uploaded to your post.

Malwarbytes locked up on me. Running again. Also I should have about 10 pro licenses coming today. Just running the free version now. Again much appreciated. I could read Hijack this logs with the best of them years ago, but got out of it a bit and went a different way in my career, now I'm back sys admin and yeah...back at it cleaning up someone else's mess.


I'll report back soon with the malwarebytes scan.

I may need to so I can brush up on all the new crap they've came out with. Damn...Malwarbytes keeps locking up and not responding. I'm going to give it a few and see if it starts responding because I can't keep rebooting this server as our its our outgoing POP3 (sigh) server

Stop Malwarebytes and update Adobe Reader on this machine:



Adobe Reader out of date

Your Adobe Reader is outdated. We will fix this.

  • Get the actual software from here. Important: Uncheck any optional software (for example Google Chrome, etc.) offered.
  • Run setup and follow the instructions.
  • Click upon Start-->control panel-->add/remove programs.
  • Search for and remove any older reader versions.



Reboot the system now!



Tell me if the problem is still detected.

Malwarebytes started running again, going to let it finish.

I'm updating the Adobe now.



Adobe...REALLY?!! This server isn't even used for anything but backups and our outgoing Pop server. Perhaps I should update all our clients as well I'm guessing?

Re-running it, one of my other admin's didn't know it was running and terminated my damn session. ugh. Lol.


Hasn't found anything yet, but MSE did find another instance pop up when I just rebooted. So I'm re running the scan. I wish my pro version licenses would get here.


Yesterday when I ran malwarbytes it never found any infection. We'll see, hang with me I appreciate it.
