TDSSKiller appears to have found the mbr infection and removed it. Is MSE still complaining?

aswMBR is still showing a partition that looks a bit funny. The third one:

11:08:21.734 Disk 0 Partition 3 00 17 Hidd HPFS/NTFS NTFS 1 MB offset 312496380

It's too small to be legitimate and the type is one used by malware so you might want to remove it. Easiest way is to:


Do the following:
  • Click on the Start button and then choose Control Panel.
  • Click on the System and Security link.

    Note: If you're viewing the Large icons or Small icons view of Control Panel, you won't see this link so just click on the Administrative Tools icon and skip to Step 4.
  • In the System and Security window, click on the Administrative Tools heading located near the bottom of the window.
  • In the Administrative Tools window, double-click on the Computer Management icon.
  • When Computer Management opens, click on Disk Management on the left side of the window, located under Storage.

    After a brief loading period, Disk Management should now appear on the right side of the Computer Management window.

    Note: If you don't see Disk Management listed, you may need to click on the |> icon to the left of the Storage icon.

It should list the three partitions at the top. It should be easy to see which is the small one. Look in the Capacity column (you may need to slide to one side to see the column) (It may say 2 M instead of 1 M - aswMBR and MS seem to count things differently.) Normally it won't have Drive letter. To remove it you just right click on it and there should be an option to Delete Volume.

Reboot and that should do it.

Following is my usual cleanup routine. You can skip the System Restore cleanup if you like since the virus wasn't really active after the reload.


We need to cleanup System Restore:

Copy the following:

:Commands
[CLEARALLRESTOREPOINTS]
[Reboot]

Right click on OTL and Run As Administrator. In the Custom Scans/Fixes box at the bottom, paste in the copied text (Ctrl + v) and then hit Run Fix.

That will get the last of the malware off the system.



You can uninstall or delete any tools we had you download and their logs.
To uninstall combofix, copy the next line:

"%userprofile%\Desktop\combofix.exe" /Uninstall

Start, All Programs, Accessories then right click on Command Prompt and Run As Administrator.
then right click, Paste, then hit Enter.

OTL has a cleanup tab if you go there it will remove itself and its logs.

To hide hidden files again (OTL may do it for you):

Vista or Win7

# Open the Control Panel menu and click Folder Options.
# After the new window appears select the View tab.
# Remove the check in the checkbox labeled Display the contents of system folders.
# Under the Hidden files and folders section select the radio button labeled Do not Show hidden files and folders.
# Check the checkbox labeled Hide protected operating system files.
# Press the Apply button and then the OK button and exit My Computer.

Also make sure you have the latest versions of any adobe.com products you use like Shockwave, Flash or Acrobat.

Whether you use adobe reader, acrobat or fox-it to read pdf files you need to disable Javascript in the program. There is an exploit out there now that can use it to get on your PC. For Adobe Reader: Start, All Programs, Adobe Reader, Edit, Preferences, Click on Javascript in the left column and uncheck Enable Acrobat Javascript. OK Close program. It's the same for Foxit reader except you uncheck Enable Javascript Actions.

To help keep your programs up-to-date you should download and run the UpdateChecker:
http://www.filehippo.../updatechecker/
(You don't need to download Betas and if there is a program you don't use you can just uninstall it rather than update it. Exception is MSN messenger which appears to be part of Windows.)
If you get a blocked program notice after installing updatechecker then change it to not run at start then manually run it once a week.
Seems to work best if Firefox is the default browser. You can also try Secunia PSI http://secunia.com/v...l/download_psi/ Same kind of info. You don't need both.
If you use Firefox then get the AdBlock Plus Add-on. WOT (Web of Trust) is another you might want to try.
The equivalent to AdBlock Plus for IE is called Simple Adblock and you should install it too: http://simple-adblock.com/
The free version only blocks 200 ads a day so another reason to use Firefox or Chrome.

If Firefox is slow loading make sure it only has the current Java add-on. Then download and run Speedy Fox.
http://www.crystalidea.com/speedyfox . You can run it any time that Firefox seems slow.

Be warned: If you use Limewire, utorrent or any of the other P2P programs you will almost certain be coming back to the Malware Removal forum. If you must use P2P then submit any files you get to http://virustotal.com before you open them.


If you have a router, log on to it today and change the default password! If using a Wireless router you really should be using encryption on the link. Use the strongest (newest) encryption method that your router and PC wireless adapter support especially if you own a business. See http://www.king5.com...-120637284.html and http://www.seattlepi...ted-1344185.php for why encryption is important. If you don't know how, visit the router maker's website. They all have detailed step by step instructions or a wizard you can download.
