Hi,

I've just started having this issue where my anti-virus (NOD32 2.5) flags a trojan threat each time I open or close an application. This occurs for any application I open. I've pasted an example of the threat report below. This one I got after opening Firefox.

<<<copy/paste>>>

Time Module Object Name Threat Action User Information
12/19/2009 17:21:11 PM AMON file C:\Documents and Settings\Shaun\Application Data\Macromedia\Common\5868201819.exe a variant of Win32/Riern.B trojan quarantined - deleted SHAUN\Shaun Event occurred on a new file created by the application: C:\Program Files\Mozilla Firefox\firefox.exe. The file was moved to quarantine. You may close this window.

<<<end copy/paste>>>

I've carried out a full system scan (again using NOD32) on Safe Mode which flagged out a .dll which was apparently infected with Riern.D which I subsequently chose to delete. Unfortunately, I didn't take note of the .dll and NOD32 did not save a log of that scan.

Hope someone can help me out with this.

I'm running WinXP, by the way. I'm not too sure what other info might be needed to help troubleshoot but I'll provide as necessary.

Thank you for your time!!

Regards,
Shaun

:trumpet: Please download RKill by Grinler

Link #1
Link #2
Link #3
Link #4

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Download Link #1.
  • Save it to your Desktop.
  • Double click the RKill desktop icon.
    If you are using Vista please right click and run as Admin!
  • A black screen will briefly flash indicating a successful run.
  • If this does not occur please delete that application and download Link #2.
  • Continue process until the tool runs.
  • If the tool does not run from any of the links tell me about it.
:flowers: Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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.
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.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

Thanks a lot for the time and help, rigel. I'm at the office right now so I'll do as suggested when I'm home and let you know the results.

Thanks again!

Hi rigel,

That did not go very well.. :thumbsup:

It was all smooth until step 3. After installation of Malwarebytes' (MWB), after clicking "Finish" with "Update...." and "Launch..." checked, the program hung and was not responding while connecting to the MWB server (I swear I waited). I then did the following:

- alt+ctrl+del-ing to force close MWB
- Attempting to restart MWB produced a "MWB is already running" dialogue box.
- Restarted computer
- Closed Ad-Aware Anniversary (AAA)
- Ran MWB, no problem
- Clicked on "Update" in the "Update" tab, no problem. MWB updated successfully.
- "Perform Quick Scan" as per your instructions
- Went for dinner
- Came back to find MWB had closed by itself at some point
- Ran MWB again
- "Perform Quick Scan" again
- MWB scan produced 16 instances
- Clicked on "Remove Selected"
- MWB hangs again
- Forced program closed
- Restarted computer
- Closed AAA
- Re-ran MWB scan
- MWB produced "Error code: 722 (0,7)" numerous times during scan but completed scan. Scan found 31 instances.
- Tried to be smart and clicked on "Save logfile"
- MWB crashed with the ol' "MWB has encountered a problem and will close" window
- Uninstalled MWB, restarted and ran the MWB cleaning utility as suggested on the MWB site (restarted again)
- Installed MWB (with AAA and NOD32 de-activated)
- MWB hangs again like before
- Forced program closed and restart MWB
- Same problem after clicking on "Update"

And that's how I spent my evening.. :flowers:

How should I proceed?

Thanks again for the time and effort! I must apologise if I'm inadvertently doing something wrong.

Edit: In Step 2, I ran the #4 Link, if that helps any.
