BSOD when logging on after using Malwarebyte


Recommended Posts

Sorry if this is wrong place to put this. Unfortunately I do no have the log file for the scan as I can't even enter the PC for more then a few seconds without BSOD and when I access Safemode with networking I cannot connect to the internet there.

Now... How do I explain?

I downloaded this because google kept redirecting me, but now I'm afraid my stupidity has only led to more destruction then the virus would have caused. I don't even know how I got the virues, I certainly never downloaded anything stupid. I don't know what website I entered that must've gave it to me. I did a quick scan as recommanded, and got 60 infected files. Now I'm worried I should have posted the log here, and ask if any of it was a false positive, but I didn't. I didn't think it was a false positive, and I deleted them. I restarted my computer as malwarebyte said to. But within seconds of logging in, I get the BSOD. EVERY time I log in I get the BSOD. And now I must show a very depressng emote: I already lost my old PC to a virus, I don't want to lose ANOTHER.

I know I haven't given y'all much to work with, but what steps do you think I must take? I've already began to savage my documents that I can't afford to lose and back them up on my USB, in case my computer becomes unusable.

Oh when I run it in safe mode, it says these 2 files describe the problem...

minidump/061911-44515-01.dmp

appdata/local/temp/WER-3345234-0.sysdata

I'm considering I may as well reinstall windows 7, with all my documents backed up, but I'd like to see if I can solve this first.

Hi and :welcome:

Do you have a flashdrive you can use to transfer logs from your infected computer to a computer with working internet?

We Need to Diagnose Your BlueScreen

  1. When you boot your machine, press F8 to list the startup options, exactly as you would if you were trying to enter Safe Mode
  2. Select "Disable Automatic Restart on System Failure", as shown here:
    advancedoptions.png
  3. When your system BSODs, write down the STOP error code, as well as any written out error message back here. The STOP error will always appear, but the message may not. You are looking for this:

Please post me the error(s).

Hi, I did a system restore before your post (to undo the massive change malwarebyte made to my regestry) and it seemed to fix my PC for a few days. But, I was relucant to re-scan and re-delete all the files again for it would just happen again. I was going to post a log up here, and I did (but I can't find the thread) In any case, in the next day, that is today, I got the BSOD again, now It happens every time I log in (except safe mode) again.

STOP: 0x0000008E (0XC0000005, 0X8A4287487, 0X9CE4AF7C, 0X00000000

attapor.sys adress 8A28100, Data stamp 4a5bbf16

Please also find attached the scan log I did in safe mode today. Which ones should i remove?

Hi again, can you run the following from safe mode?

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!

Unfortunately you had a nasty rootkit on your computer. Even though it is gone now, please read the following information first, before continuing with the cleanup.

BACKDOOR WARNING

------------------------------

One or more of the identified infections is known to use a backdoor.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the infection has been identified and cleaned, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do. If you decide to go through with the cleanup, please proceed with the following steps.

COMBOFIX

---------------

Please download ComboFix from one of these locations:


Bleepingcomputer
ForoSpyware

  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. (Click on this link to see a list of programs that should be disabled. The list is not all inclusive.)
  • Double click on Combofix.exe and follow the prompts.
  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.

**Please note: If the Microsoft Windows Recovery Console is already installed, or if you are running Vista, ComboFix will continue it's malware removal procedures.

Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

RC_successful.gif

Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\Combofix.txt in your next reply.

I knew backdoor trojans could do that, but I didn't realise that it meant my computer couldn't be trusted again, even after the virus is gone. I don't do banking on my PC but I do use facebook, and other forum places. These are things I don't really care if they get hacked (I.e Sims 3 forums) As for my facebook, I guess for the time being I could just not use it on that PC. However, what other risks might be apparent even if I don't use facebook, banking etc?

I'm not quite ready to reinstall my PC, I've got a few important programs I might not be able re-install for months. So for now, I'll continue with clean-up.

I haven't done it yet, but I will tomorrow. (Im currently using a laptop)

To be sure you can change your facebook password and things like that. After you do this, most likely you can use it safely.

In your case best would be indeed to continue the cleanup for now, so you have at least a clean computer to work with.

That sometimes happens, and a reboot takes care of the issue. It is nothing to worry about.

Can you please rerun combofix and post me the new log? A file was flagged as infected, but not shown further on in the log and I'd like to see if it is still there or not.

I don't know much of this but it said c:\windows\system32\userinit.exe . . . is infected!! and I assume thats what your talking about.

It was in the list of "Other Deletions" wasn't it? Are you sure it wasn't saying it was infected and deleted at same at the same time? Again, I do not know :P

I will do the scan soon as possible.

Lets also make sure everything else is up to date and in order, to avoid such problems in the future. :)

P2P WARNING

-------------------

Going over your logs I noticed that you have uTorrent installed.

  • Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs.
  • They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites.
  • Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users.
  • The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications.

It is pretty much certain that if you continue to use P2P programs, you will get infected again.

I would recommend that you uninstall uTorrent, however that choice is up to you. If you choose to remove these programs, you can do so via Start > Control Panel > Add/Remove Programs.

If you wish to keep it, please do not use it until your computer is cleaned.
