Hi everyone!

I updated Spybot to the new version and ran a scan and it found the banker trojan. I rescanned with spybot, and scanned with Avira AV (free edition), MBAM, SuperAntiSpyware, Kaspersky online and F-Secure online. None of them found anything significant. My questions are: Is it possible I'm still infected by something hiding? Could it have been a false positive? I have Avira AV Comodo firewall and BOClean all running real time protection. Do I have to change my bank codes?

I appreciate everyone's help.

Spybot logs are almost impossible to decipher, but what did it find and where?

It found something it called "Banker", and it was in the registry. Does that help?

Hi!

I found the following description on the Spybot web site:

These Banker trojan horses disguise themselves as system files and browser helper objects (BHO). They run in background, connect to their malicious websites and try to perform phishing attacks on banking accounts.

Does that mean my bank accounts are compromised?

That usually what that family of trojans does

Let's use MBAM to have a look

Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • 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 updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
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 and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. 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 after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Here's probably the worst example of what malware can do with banking

That's unbelievable!

I did another quickscan, and then a full scan with MBAM and they came out clean. Does that mean I'm clean? Can I switch my bank codes from this computer now?

Thanks for all your help! You are truly fighting the Dark Side of the internet! :thumbsup:

Something tells me you're a star wars fan :flowers:

To be on the safe side I wouldn't use any computer, if you had to then I would use a very secure one.

We could run some rootkit scanners

But why don't we look at a spybot log that showed that banker trojan?

I couldn't find the spybot log. I looked in advanced mode under tools/veiw report/view previous report but there was nothing there?

I couldn't find any fixes log or tab, but I found the file paths in recovery. (I didn't recover the files!)

Banker

Browser helper object
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{8CA5ED52-F3FB-4414-A105-2E3491156990}

Class ID
HKEY_CLASSES_ROOT\CLSID\{8CA5ED52-F3FB-4414-A105-2E3491156990}

I hope that helps.

Thank you for all your help!!!

It wasn't a false positive, but what I found was some adware assoicated with that, not the banker trojan
