Greetings,

I've recently come across some trojans that were found by Symantec Endpoint Protection and Avira auto-scans. The notifications popped up after I brought my laptop out of hibernation (which is how I normally leave it when unused).

Symantec tells me that cleaning and quarantining was not successful with a handful of the trojans and is located under:

C:\Documents and Settings\All Users\Application Data\Symantec\ ________

but I cannot find them.

I am currently running Firefox 3.6.3

Any help would be greatly appreciated,
Thank you,

Alan

Hello,did Avira say they were quarantined?? Do you have these 2 AV's active??

C:\Documents and Settings\All Users\Application Data\Symantec\_______ <<---- This is what it shows as a location??

Let's gt another opinion...
Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.
Before you save it rename it to say zztoy.exe

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 timely reply.

Yes, I have both Symantec and Avira on at the same time.

Symantec shows the locations as:

c:\Documents and Settings\All Users\Application Data\Symantec\Symantec Endpoint Protection\xfer
c:\Documents and Settings\All Users\Application Data\Symantec\SRTSP\Quarantine\

Here is the MBAM log:

Symantec and Avira also show no threats but I'm wondering where these things are considering the scans don't show anything.

Ok the problem may be having 2 AV's active.. They can get stuck searching each others Quarantine or database..

Empty Symantec quarantine,turn off Avira and rescan with Symantec.

I scanned again using Symantec with Avira off but it picked up nothing aside from some tracking cookies.

I'm not completely sure how to dump the quarantine. Do you know how?

Thanks

On the Monitors tab, on the Logs tab, under Log type, select Risk, and then click View Log. Under Action, click Delete from Quarantine.

from Purge Quarantine
