I followed the XP malware removal guide and here are the logs files. The problem was not solved by running all these tools

Default Re: Infected with win32\Kryptic Trojan

Welcome to Major Geeks!


Uninstall the below old versions of software:
Java(TM) 6 Update 29
Java(TM) SE Development Kit 6 Update 23

Now we need to use ComboFix
  • Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
    • If it is not on your Desktop, the below will not work.
  • Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
  • If ComboFix tells you it has expired or need to be updated to a new version, make sure you allow it to update.
  • Open Notepad and copy/paste the text in the below quote box into it:
Quote:

"Antivirus Protection 2012 SH"=--
[-HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\SearchScopes\{afdbddaa-5d3f-42ee-b79c-185a7020515b}]
  • Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
  • At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
  • You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
  • Now use your mouse to drag CFscript.txt on top of ComboFix.exe
  • Follow the prompts.
  • When it finishes, a log will be produced named c:\combofix.txt
  • I will ask for this log below
Note:

Do not mouseclick combofix's window while it is running. That may cause it to stall.

If after running Combofix you discover none of your programs will open up because you recieve the following error: Illegal operation attempted on a registry key that has been marked for deletion then you will need to reboot your computer which will normally fix this problem.

After reboot, now install the current version of Sun Java from: Sun Java Runtime Environment

Now run Ccleaner. Only use the Run Cleaner button. Do not run anything else on any other forms.

Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Win7, don't double click, use right click and select Run As Administrator).

Then attach the below logs:
  • C:\ComboFix.txt
  • C:\MGlogs.zip
Make sure you tell me how things are working now!

Default Re: Infected with win32\Kryptic Trojan

Ok,

I followed all the steps and here are the log files. During combofix, I temporarily disabled AVG.

After running combofix, a reboot had to be done, and AVG starts with reboot. Immediatly after reboot, AVG gave again the same error that win32/Kryptic was detected...

Seems not to be solved yet...

Now shut down your protection software now (antivirus, antispyware...etc) to avoid possible conflicts.
  • Double-click OTL.exe to run. (Vista/7 right-click and select Run as Administrator)
  • Copy the text in the code box below and paste it into the text-field.

For the moment, symptoms seem to have disappeared.

Do the logs confirm all is OK?

Yes. And the below will remove the items from System Restore that you see with AVG


If you are not having any other malware problems, it is time to do our final steps:
  1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
  2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
    • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
    • "%userprofile%\Desktop\combofix" /uninstall
      • Notes: The space between the combofix" and the /uninstall, it must be there.
      • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
  3. Go back to step 6 oof the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
  4. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
  5. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
  6. If running Vista or Win 7, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
  7. Go to add/remove programs and uninstall HijackThis.
  8. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
    related to MGtools and some other items from our cleaning procedures.
  9. If you are running Win 7, Vista, Windows XP or Windows ME, do the below:
    • Refer to the cleaning procedures pointed to by step 7 of the READ ME
      for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
    • Then reboot and Enable System Restore to create a new clean Restore Point.
  10. After doing the above, you should work thru the below link:
