Cannot remove win32.backdoor.sinowal

Recommended Posts

Hi

I don't remember if I have ever used Safe Mode on this pc.

I've never had any problems with viruses or anything, there hasn't been a reason to use it(until now)

 

Ok, I ran Dr Web in normal mode.

Here's the log:

 

zanda.exe;c:\norman\npm\bin;Sannsynlighvis BACKDOOR.Trojan;Incurable.Deleted.;

ComboFix.exe\32788R22FWJFW\psexec.cfexe;C:\Documents and Settings\Eier\Skrivebord\ComboFix.exe;Program.PsExec.171;;

ComboFix.exe;C:\Documents and Settings\Eier\Skrivebord;Archive contains infected objects;Moved.;

KillWind.exe;C:\hp\bin;Tool.ProcessKill;Moved.;

Terminator.exe;C:\hp\bin;Trojan.KillApp.30208;Moved.;

A0000067.EXE;C:\System Volume Information\_restore{93A41DA8-9662-40FA-86B9-06914D114A2F}\RP2;Program.PsExec.170;Moved.;

PSEXESVC.EXE;C:\WINDOWS;Program.PsExec.170;Incurable.Moved.;

 

I know what that zanda.exe is. That has something to do with my virusprogram(Norman).

When Dr. Web removed it, there was a red X on the Norman icon saying: zanda is not running.

When i rebooted it seems that the virusprogram didn't start at all, there's no icon(near the clock)

 

It's only a week or so since I scanned the pc with Norman.

It did find this: C:\System Volume Information\_restore{93A41DA8-9662-40FA-86B9-06914D114A2F}

I turned off system restore and scanned again, but it didn't find it then, so I thought I got rid of it.(guess I didn't)

But Norman never found any of these :huh:

PSEXESVC.EXE;C:\WINDOWS;Program.PsExec.170

Terminator.exe;C:\hp\bin;Trojan.KillApp.30208

KillWind.exe;C:\hp\bin;Tool.ProcessKill

 

Are they viruses?

Dr. Web found zanda and ComboFix, but they are not viruses :)

 

And a question: I use Norman only because I get it for free from my isp.

Are you familiar with Norman? Should I get rid of it and use AVG instead?

And do you know if AVG use less memory than Norman?

I think Norman use to much. (well actually I don't know that cause I haven't used any other and compared :D )

Hi

 

Looks like none of those findings was really bad one. You had "Heuristic analysis" unchecked as instructed, didn't you? If checked then it may find false positives (=legal stuff falsely flagged as malicious).

 

Let's move those findings back.

 

Copy following files back to their original locations:

C:\Documents and Settings\Eier\DoctorWeb\Quarantine\KillWind.exe -> C:\hp\bin

C:\Documents and Settings\Eier\DoctorWeb\Quarantine\Terminator.exe -> C:\hp\bin

C:\Documents and Settings\Eier\DoctorWeb\Quarantine\PSEXESVC.EXE -> C:\WINDOWS

C:\Documents and Settings\Eier\DoctorWeb\Quarantine\ComboFix.exe -> C:\Documents and Settings\Eier\Skrivebord

 

zanda.exe got deleted so you can't restore it. Only way is either reinstall Norman or uninstall remnants of it and then install some other antivirus program. I don't have much experience of Norman. I had it for a moment years ago on my lappie (got it pre-installed). Since you don't have to pay for it then I think it's ok that I recommend some free alternatives. Good free antivirus programs are:

Antivir

Avast! and

AVG Free Antivirus

 

Since you haven't accessed safe mode before we can't say if it has been like that all the time. Have you updated your graphics card drivers lately? It might be worth doing so.

Yes, I unchecked "Heuristic analysis".

Can I remove Dr. Web now? And what about this one: A0000067.EXE;C:\System Volume Information\_restore{93A41DA8-9662-40FA-86B9-06914D114A2F}\RP2;Program.PsExec.170 that's still in quarantine, should I delete it?

 

Updated the graphic driver now, but it didn't help. Can't start in Safe Mode :)

Have you ever heard of anyone with that problem before?

 

I just want to say Thank you very much for your help :)

I got rid of that sinowal :huh:

And my pc is working just fine. It worked fine with sinowal too :D It was just that it turned up every time I scanned.

But it may be a bigger problem that I can't start in Safe Mode?

May come a day when Safe Mode is the ONLY way to fix something?

Well, I guess it's time for a new pc when that happens :D

 

Thanks for all your help

Hi

 

Yes, you may uninstall Dr Web now. Deleting that item in quarantine is ok since it was already in system restore which we'll empty. :D

 

Updated the graphic driver now, but it didn't help. Can't start in Safe Mode sad.gif

Have you ever heard of anyone with that problem before?

No. I've seen all kind of weird things but never one like the one in that screenshot :huh: You might try some forum that's concentrated in general computer problems, like http://forums.whatthetech.com for example. Wish I had been able to help :)

 

 

Since there doesn't seem to be any malware left I'll give you all clean speech.

 

Well congrats, it appears your system is all clean Are you still noticing any problems? If not, it's time to secure your system to prevent against further intrusions.

 

 

THESE STEPS ARE VERY IMPORTANT

 

Let's reset system restore

Reset and Re-enable your System Restore to remove infected files that have been backed up by Windows. The files in System Restore are protected to prevent any programs changing those files. This is the only way to clean these files: You will lose all previous restore points which are likely to be infected. Please note you need Administrator Access to do clean the restore points.

 

1. Turn off System Restore.

On the Desktop, right-click My Computer.

Click Properties.

Click the System Restore tab.

Check Turn off System Restore.

Click Apply, and then click OK.

 

2. Reboot.

 

3. Turn ON System Restore.

On the Desktop, right-click My Computer.

Click Properties.

Click the System Restore tab.

UN-Check *Turn off System Restore*.

Click Apply, and then click OK.

NOTE: only do this ONCE,NOT on a regular basis

 

 

 

Now lets uninstall ComboFix:

  • Click START then RUN
  • Now type Combofix /u in the runbox and click OK

Next we remove all used tools.

 

Please download OTMoveIt2 and save it to desktop.

  • Double-click OTMoveIt2.exe.
  • Click the CleanUp! button.
  • Select Yes when the
    Begin cleanup Process?
    prompt appears.
  • If you are prompted to Reboot during the cleanup, select Yes.
  • The tool will delete itself once it finishes, if not delete it by yourself.

Note: If you receive a warning from your firewall or other security programs regarding OTMoveIt attempting to contact the internet, please allow it to do so.

 

 

 

UPDATING WINDOWS AND INTERNET EXPLORER

 

IMPORTANT: You Need to Update Windows and Internet Explorer to protect your computer from the malware that is around on the Internet. Please go to the windows update site to get the critical updates.

 

If you are running Microsoft Office, or any portion thereof, go to the Microsoft's Office Update site and make sure you have at least all the critical updates installed (Free) Microsoft Office Update.

 

 

Make your Internet Explorer more secure

 

This can be done by following these simple instructions:

From within Internet Explorer click on the Tools menu and then click on Options.

Click once on the Security tab

Click once on the Internet icon so it becomes highlighted.

Click once on the Custom Level button.

Change the Download signed ActiveX controls to Prompt

Change the Download unsigned ActiveX controls to Disable

Change the Initialize and script ActiveX controls not marked as safe to Disable

Change the Installation of desktop items to Prompt

Change the Launching programs and files in an IFRAME to Prompt

Change the Navigate sub-frames across different domains to Prompt

When all these settings have been made, click on the OK button.

If it prompts you as to whether or not you want to save the settings, press the Yes button.

Next press the Apply button and then the OK to exit the Internet Properties page.

 

 

 

The following are recommended third party programs that are designed to keep your computer clean. A link as well as a brief description is included with each item.

  • Download SpywareBlaster
    Spyware blaster is a program that stops known malicious activex controls from installing on your computer. It works by changing settings in your registry. It makes
    kill bits
    in the registry, so that certain activex controls can't install.
    If you don't know what activex controls are, see here
    You can download SpywareBlaster here here
    SpywareBlaster tutorial
     
  • hosts file:
    • Every version of windows has a hosts file as part of them.
    • In a very basic sense, they are used to locate webpages.
    • We can customize a hosts file so that it blocks certain webpages.
    • However, it can slow down certain computers.
    • This is why using a hosts file is optional!!

    Download it here. Make sure you read the instructions on how to install the hosts file. There is a good tutorial here

    If you decide to download the hosts file, the slowdown problems can usually be avoided by following these steps:



    1. Click the start button (at the lower left hand corner of your screen)
    2. Click run
    3. In the dialog box, type services.msc
    4. hit enter, then locate dns client
    5. Highlight it, then double-click it.
    6. On the dropdown box, change the setting from automatic to manual.
    7. Click ok

     

    [*]Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is susceptible to being hacked and taken over. Simply using a Firewall in its default configuration can lower your risk greatly. For more info, check this webpage out.

    See here to choose one if you don't have a 3rd party firewall.

 

Just a final reminder for you. I am trying to stress these two points.

UPDATE UPDATE UPDATE!!! Make sure you do this about every 1-2 weeks.

Make sure all of your security programs are up to date.

Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.

 

 

 

Once again, please post and tell me how things are going with your system... problems etc.

 

Have a great day,

Blade :D

Hi

 

Almost forgot one thing. Since you had that Sinowal infection it's strongly recommended you change all your passwords to new ones. Also, what brand is your monitor if I may ask? Problems in safe mode might be cos your monitor too.

Yes, all those passwords you use online. It might well be your widescreen monitor that doesn't work with low resolution of safe mode. Any chance to test with some other monitor?

Hi

 

Have you installed drivers for your monitor or are you using some general drivers that Windows installs by itself?

 

here you'll find HP w2207 LCD Monitor Driver and HP Adjustment Pattern Utility.

When I bought the monitor it came with a cd, on the cd is "HP My Display" (HP Adjustment Pattern Utility).

If there was some drivers on that cd, I don't know. I just installed what was on the cd.

 

I followed your link, updated the monitor driver, and updated "HP My Display". Thanks for the link ;)

But nothing changed. I still get that screen with the "circles" when I start in Safe Mode :)

Hi

 

I guess it's time to ask at What the Tech then. Hopefully someone there could help you with the issue :)
