Hi

Within last days experiencing problems in that receiving details referring to Trojan-Downnloader.JS.Agent.dly
I run Zone Alarm Security Suite version 8.0.059.000 and on each occasion of visiting the following site : www.ooxtv.com I rcve message saying file has been quarantined and no further action required.
The problem is that next time I visit site, another message appears of same nature with slightly different details

I am wondering if anyone is able to offer any advice as to what maybe required to resolve the problem. Is it a virus which can be fixed permanently ?

Tks your input

Please download Malwarebytes Anti-Malware 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.

Hi Budapest

Your response appreciated. Not knowing exactly what should have been done before requesting help, I had already downloaded Malwarebytes and followed the instructions. H/ever since yr response I did once again as you mentioned. i.e. removed previous version and downloaded fresh copy.
Having completed the procedure I am attaching copy of report as well as previous reports which I had saved: The previous found quite a few errors as you will observe in comparison to the current report.

Hhi Budapest

Late response regretted. In response to question, PC appears to be running OK but I reservedly say that, due to my original querry still occurs on a regular basis. I would like to attach a copy as an example of what actually does show up but due having some difficulty in actually carrying out that procedure. Perhaps you can advise me the exact/correct procedure if at all possible.
As far as removing windows.old folder I refrained from removing thus far. Reason, because of limited knowledge and the fact that it is stated the folder should be removed with care and not quite sure if any files therein are still required. Hopefully you will appreciate my predicament.

Awaiting your advice regarding inserting image file in an effort for you to see the contents

Tks

Tks for info. H/ever no need for utilizing photo bucket. Noted way to attach image in future.


Spoke to a friend who advised me to give AVG a trial. Gave it a try and immediately got better results thus far. Previous problems no longer occurring and find that PC running much better than before.
Thanks very much for your help.
