Hi there! Thanks for this paltform.

Recently my PC was infected with security essential platinum malware. i didnt had any antivirus intalled then. going through instructions given in your one of the forum i disinfected my PC from it. After that i installed norton 360. Since then, the norton is continually detecting trojan.gen and trojan.zeroaccess.b threats and resolving it. What do i do to remove this trojan. i have seen procedures given by you to get rid of it but solution seems to be specific to a particular system , as there were warnings not to use it on any PC.

i am attaching the norton log file for reference.

Pls advise what should i do to remove this risk.

Thanks

Hello and welcome to Bleeping Computer!

I am D-FRED-BROWN and I will be helping you. :)


Please print or save this topic. It will make it easier for you to follow the instructions and complete all of the necessary steps.


----------Step 1----------------
I know you've already run TDSSKiller before, but please run it one more time so we have an up-to-date idea of what may be remaining on the computer.

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Skip is selected, then click Continue > Reboot now to finish the cleaning process.
    Note: Do not choose Cure or Delete unless instructed.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.

----------Step 2----------------
Please download ComboFix.exe. Please visit this webpage for download links, and instructions for running the tool:

http://www.bleepingc...to-use-combofix

***IMPORTANT: save ComboFix to your Desktop***

* Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Please go here to see a list of programs that should be disabled.

**Note: Do not mouseclick ComboFix's window while it's running. That may cause it to stall**

Please include the C:\ComboFix.txt in your next reply for further review.


----------Step 3----------------
Please download Security Check by screen317 from here or here.
  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.

----------Step 4----------------
In your next reply, please include the following:
  • TDSSKiller's logfile
  • ComboFix's report (C:\ComboFix.txt)
  • Security Check checkup.txt
After that, please let me know: How is your computer running now? Do you have any questions or concerns you'd like me to address? Don't hesitate to ask. :)

hi D-FRED-BROWN

it seems that i have got rid of these malware. running hitmanpro did the trick for me. since last 24 hrs i am not facing any threats. also norton has stopped detecting it.

Thanks for your support and time.

It appears that this issue is resolved, therefore I am closing the topic. If that is not the case and you need or wish to continue with this topic, please send me or any Moderator a Personal Message (PM) that you would like this topic re-opened.
