Hi! I've never been in this kind of situation before, but I've encounted a random popup called Antivirus 2009 and since that day (3-4 days ago), many popups will just appear out of nowhere. I've downloaded Malwarebytes's Anti-Malware and it came up with 24 infected files. But somehow, some of them just keep reappearing, especially the Trojan.Agent. Actually, Malwarebytes doesn't seem able to delete it.

I don't know if I am posting in the right section though. I would really appreciate some help because I wonder if someone is currently stealing my personal information or even my passwords. Thank you very much!

Hi taskinillusion and welcome to BC :thumbsup:

Please print out and follow these instructions: "How to use SDFix". <- This program is for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to renable you anti-virus and and other security programs before connecting to the Internet.
-- If the computer has been infected with the VirusAlert! malware warning from the clock and the Start Menu icons or drives are not visible, open the SDFix folder, right-click on either the XP_VirusAlert_Repair.inf or W2K VirusAlert_Repair.inf (depending on your version of Windows) and select Install from the Context menu. Then reboot to apply the changes.

Then please update and rerun Malwarebytes - post a new log...

I clicked on the Run menu option of the Start button, but when I typed C:\SDFix\RunThis.bat, it says that it is not available on my computer and that I should insert correctly my devices. I should have copied the whole message though. I checked (Start, then My Computer) and SDFix is only available in the hardisk (D:). Should I type D:\SDFix\RunThis.bat instead?

By the way, I have installed SDFix.exe and here's the message, if that can help.



SDFix has been extracted to %systemdrive%\SDFix\
(Drive that contains the Windows directory - typically C:\SDFix)

Open the SDFix folder in Safe Mode and double click the RunThis.bat file to start the fixtool
If RunThis.bat is started in Normal Mode, options to download and run Anti-Virus command line scanners are displayed

Catchme.exe Stealth Malware Detector by GMER is also included in the SDFix folder

Additional SDFix Instructions & screen shots can be found here - http://www.bleepingcomputer.com/forums/t/131299/how-to-use-sdfix/

Is you boot drive, drive D? If that is the main system drive, yes, please use D:\SDFix\RunThis.bat

Since all the "important" files are on that drive, yes I guess it is my main system drive.

Should I download the free version for home users or the trial one?

And when you say "On the left, make sure you check C:\Fixed Drive.", should I change it for D:\Fixed Drive. ?

Yes, use the free version.

Yes to that too. Sorry taskinillusion, our "guides" are geared mainly for C: being the primary drive.

I just realized that I forgot to disable my Internet connection before running ATF-Cleaner and SUPERAntiSpyware. Can it affect the results?
With SUPERAntiSpyware, I only scanned my main system drive and not the other ones. Is it okay?

Edit:
I ran Malwarebytes and it still exists... I hope there is another step :thumbsup:

Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

We need to clear system restore...
The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok"
  • Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" Tab.
  • Click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Update and rerun Malwarebytes with D: substituted for C: You should see 0's

Wow, thank you so much! I really appreciate this because it was driving me crazy!
Can I delete ATF-Cleaner, SUPERAntiSpyware and SDFix now? And do you know what kind of information this malware usually takes?

Yes, if you wish. I personally recommend uninstalling SuperAntiSpyware because it tends to slow your computer's start-up. You can Keep ATF-Cleaner. It only runs when you tell it to, and is a good tool to "take out the trash."
