MBR infected ? not sure ; I think so


Recommended Posts

Hi;  hope I've followed all your protocols  for this site.

I just installed a new SSHD 500 Gb ; installed Win 7 64 bit on my K53E Asus laptop. Did reinstall from Asus  disks successfully. Installed a few favorite programs- VLC ,Malwarebytes, ASC7,AVG free,Trans.qt, . Did some surfing, torrenting etc.and everything seemed fine for a couple of days. I was experiencing Windows Explorer " stopped responding" though . This is not completely new to me from previous times , but now it was getting worse  so I started to explore  the issue on the web and read about it wherever I could. I also decided to explore  different virus protection etc. I found and tried Vipre,  ; Bit Defender installed an extension scanner  from just trying it once. I left it  there. Next  I went to Source Forge  to see what open source has.I tried Clamwin, Eset, Moon Secure Antivirus, Avira free . When I ran Clamwin I noticed it wasn't able to open a whole bunch of C:/ files. Tried Eset. Same thing.   Copied and googled partial log from Winclam and found that it looked like I might  have an MBR problem. Tried Cce and a couple of other boot scanners with no success. Malwarebytes also returned nothing  for me. The Moon app was prevented from working  at first,  but finally did , but found nothing either. One of them, I think Cce found a file and  I deleted it. I didn't save anything though. Something like  raeeh. ; sorry.   All this time  things are starting to happen too; gets worse.   browser hung up some ; much slower .Other errors.  Then I came across your forum. I really will be lucky  if I can even do what you've asked ;that's how much I don't know.                   attach.txt

              dds.txt                thank you very much


P.S. sorry about the no tag ; couldn't find them

OK  .  Here are both rootkit files and  the jrt log. For both rootkit scans nothing showed up to be cleaned.   ??


 Also , the event logs for the jrt scan were not saved. Is this normal?

It's confusing . The machine seems to be doing better. However when I ran ESET scanner I didn't clean what it found. I was waiting for your go ahead.  Also were you able to determine anything form the  png. I used?   When I originally read an article about MBR virus' and my symptoms fit I had hoped to be able to run boot  rootkit scans  but when I tried Comodo boot rescue disk I couldn't enable any network connections so it couldn't update so I failed with that.

 So far I tried to follow your instructions but I don't know what we've done that would have cleaned anything . Have we? So , I'm not sure something  isn't still hiding in MBR.

BTW...   I'm convinced now , with all the help etc. from MWB to get all your latest  PRO edition products. Also I downloaded about 20 tools from Bleepingcomputer.com  ..   Probably won't know how to use all of them . Slowly  learning  a little bit . KNOW TO BE REALLY CAREFUL. Mostly observational  for me as opposed to taking any actions.

So I guess I should run ESET again and clean the 3 items this time? 

Do we have discussions on this forum?

To answer your question : I haven't been going out on the web or doing much of anything while we've been working on this stuff to be able to tell of any problems . I t does seem to be doing better generally.   Not hanging up or not responding . Speed is improved. My desire is to make sure all is good and then reinstall again. What do you think?

The items found by ESET are not really much of a threat they're being flagged because they add adware type programs as part of the installer, otherwise known as PUP (Possibly Unwanted Programs).  You can delete them or if you do use them make sure to choose Custom install and uncheck any add-on programs or features.



Please download the following scanner from Kaspersky and save it to your computer: TDSSkiller

Then watch the following video on how to use the tool and make sure to temporarily disable your security applications before running TDSSkiller.

If any infection is found please make sure to choose SKIP and post back the log in case of a False Positive detection.

Once the tool has completed scanning make sure to re-enable your other security applications.

At this time there are no more signs of an infection on your system.
However if you are still seeing any signs of an infection please let me know.

Let's go ahead and remove the tools and logs we've used during this process.

Most of the tools used are potentially dangerous to use unsupervised or if ran at the wrong time.
They are often updated daily so if you went to use them again in the future they would be outdated anyways.

The following procedures will implement some cleanup procedures to remove these tools.
It will also reset your System Restore by flushing out previous restore points and create a new restore point.
It will also remove all the backups our tools may have created.

  • Push the "Windows key" + "R" (between the "Ctrl" button and "Alt" Button)
  • Please copy and past the following into the box ComboFix /Uninstall and click OK.
  • Note the space between the X and the /Uninstall, it needs to be there.


Remove the rest of the tools used:
Please download
and save it to your Desktop. This tool will remove all the tools we used to clean your pc.

  • Double-click OTCleanIt.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 go ahead and delete it by yourself.
  • If asked to restart the computer, please do so


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

AdwCleaner Removal:

A lot of reading here but if you take the time to read a bit of it you'll see why/how infections and general damage are so easily inflicted on the computer. There is also advice on how to prevent it and keep the system working well. Don't forget about good, solid backups of your data to an external drive that is not connected except when backing up your data. If you leave a backup drive connected and you do get infected it can easily damage, encrypt, delete, or corrupt your backups as well and then you'd lose all data.
Nothing is 100% bulletproof but with a little bit of education you can certainly swing things in your favor.

If you're not currently using Malwarebytes PRO then you may want to consider purchasing the product which can also help greatly reduce the risk of a future infection.
