Hi there, new to the board and new to malware.

I hope I'm posting correctly.

I run my Norton Anti-virus scan weekly and this week it discovered the trojan "Trojan-Spy.HTML.Smitfraud.c". No problems were identified last week.
It was unable to repair, quarantine, or remove this trojan.

I did some internet searching and found what I thought might help - the smitfraudfix program and ran it in safe mode as suggested.
It did it's thing and after rebooting I tried a second Norton scan and the trojan was still detected.
I also ran Super Anti-Spyware which did not detect anything.

I also downloaded hijackthis and made a log but at that point I realised that I was far out of my depth as I couldn't understand the information given.

Any advice as to how to proceed would be much appreciated.

Thanks in advance.

Hello and welcome. Did you run options 1 & 2 already in Smitfraud? Ther should be a log saved in C:\rapport.txt. Post that please.

A;so Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Thanks for the advice.

I ran the Malwarebytes program and 3 items popped up which I removed.

That log is as follows:

Malwarebytes' Anti-Malware 1.38
Database version: 2407
Windows 5.1.2600 Service Pack 3

11/07/2009 11:20:00 AM

Objects scanned: 95293

Memory Processes Infected: 0
Memory Modules Infected: 0

Files Infected: 1

Memory Processes Infected:

Memory Modules Infected:

Registry Keys Infected:
HKEY_CLASSES_ROOT\popcaploader.popcaploaderctrl2 (Adware.PopCap) -> Quarantined and deleted successfully.
HKEY_CLASSES_ROOT\popcaploader.popcaploaderctrl2.1 (Adware.PopCap) -> Quarantined and deleted successfully.

Registry Values Infected:
(No malicious items detected)

Registry Data Items Infected:
(No malicious items detected)

Folders Infected:
(No malicious items detected)

Files Infected:
C:\Program Files\setup.exe (Rogue.Installer) -> Quarantined and deleted successfully.

I am not sure if that did the trick or not - or if I just had other malware on the computer that was not detected.

I then realised that I did not run smitfraudfix option number 1 which was to scan - i simply did option 2 - so I redid 1 and 2 in safe mode.
Log is as follows:

SmitFraudFix v2.423

Scan done at 11:45:12.32, 11/07/2009

I hope that did the trick.

Again I have a bit of trouble actually understanding the logs, so if you have the time and see some obvious malware remaining, I of course would appreciate any help possible.

I guess at this point I will try to rerun my Norton AV and see if it still detects anything - would have done that before posting, but it takes about 2 hours to complete and I thought to put some information up first.

Thank you again.

Unfortunately, when I ran the Norton Antivirus scan again, the Trojan was still present. Apparently, this is where it is located:

C:\Documents and Settings\Florence\Application Data\Sun\Java\Deployment\cache\6.0\57\32952e79-50f20c4a

Any help getting rid of this would be appreciated. Thanks in advance!

Hi we can try try a tool inside MBAM..
FILE ASSASSIN
OK, let's use MBAM's FileAssassin feature.

Open MBAM again.Click the More Tools tab and then the Run Tool button
Now browse to the file(s) we want to remove using the drop down box next to Look in: at the top.
Locate the file(s), click Open.
You will be prompted with a message warning: This file will be permanently deleted. Are you sure you want to continue?. Click Yes.
If removal did not require a reboot, you will receive a message indicating the file was deleted successfully, however, I recommend you reboot anyway.

Caution: Be careful what you delete. FileAssassin is a powerful program, designed to move highly persistent files. Using it incorrectly could lead to disastrous problems with your operating system.

Thanks for the advice.

I actually tried something that maybe I shouldn't have prior to getting the last response. I went to the file in question and was not able to remove it - but I was able to delete the folder it was in. Subsequently I uninstalled Java and deleted the Java folders. Also emptied the recycle bin and then ran ccleaner.

After rebooting, reran the Norton AV and the scan finally came up as clean.

I'm hoping that all is well. If you think I just made a horrible mistake and just made the virus hide somewhere else on the system, please let me know.

Thank you again for all the help.

Ok that's was good.. Glad it' done.
If you are reinstalling Java...
:
  • Download the latest version of Java Runtime Environment (JRE) Version 6 and save it to your desktop.
  • Look for "Java Runtime Environment (JRE)" JRE 6 Update 14.
  • Click the Download button to the right.
  • Select your Platform: "Windows".
  • Select your Language: "Multi-language".
  • Read the License Agreement, and then check the box that says: "Accept License Agreement".
  • Click Continue and the page will refresh.
  • Under Required Files, check the box for Windows Offline Installation, click the link below it and save the file to your desktop.
  • Close any programs you may have running - especially your web browser.
[*]Then from your desktop double-click on jre-6u14-windows-i586-p.exe to install the newest version.[/list]

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and 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.

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, then 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.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
