My POS Software Monitor is reporting the following:

 

JS:Trojan.JS.Downloader.AP  VIRUS C:\Users\User\AppData\Local\Microsoft\Outlook\m.hoyer@wippell.com.ost\(INFECTED_JS)

 

... but is unable to quarantine it.  How do I go about correcting the situation?

 

Thanks for your help.

Welcome to BC...

 

Which security program(s) do you have installed and which one is reporting the Trojan?

 

Use the programs below to clean, remove adware and remove malware.

 

 

Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the

Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of toolbars....especially Google.

After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.

CCleaner - PC Optimization and Cleaning - Free Download

 

Download Malwarebytes' Anti-Malware from Here

Double-click mbam-setup-2.X.X.XXXX.exe to install the application (X's are the current version number).

  • Make sure a checkmark is placed next to Launch Malwarebytes' Anti-Malware, then click Finish.
  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • When MBAM is finished scanning it will display a screen that displays any malware that it has detected.
  • Click the Remove Selected button.
  • MBAM will now delete all of the files and registry keys and add them to the programs quarantine. When removing the files, MBAM may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot, please allow it to do so.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.

POST THE LOG FOR  REVIEW.

 

Download AdwCleaner by Xplode onto your desktop.

  • Close all open programs and internet browsers.
  • Double click on adwcleaner.exe to run the tool.
  • Click on Scan button.
  • When the scan has finished click on Clean button.
  • Your computer will be rebooted automatically. A text file will open after the restart.
  • Please post the contents of that logfile with your next reply.
  • You can find the logfile at C:\AdwCleaner[S1].txt as well.
  • download Junkware Removal Tool to your desktop.
  • Shut down your protection software now to avoid potential conflicts.
  • Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message
  • Hold down Control and click on this link to open ESET OnlineScan in a new window.
  • Click the esetonlinebtn.png button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
  • Click on esetsmartinstaller_enu.exe to download the ESET Smart Installer. Save it to your desktop.
  • Double click on the esetsmartinstaller_enu.png icon on your desktop.
  • Check "YES, I accept the Terms of Use."
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Under scan settings, check "Scan Archives" and "Remove found threats"
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, click List Threats
  • Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Click the Back button.
  • Click the Finish button.
  • NOTE:Sometimes if ESET finds no infections it will not create a log.

The infections are being reported by POS Software Monitor.  I wanted to paste a screenshot of the error message, but don't see how to do that.  The two threats are listed as:

 

JS: Trojan.JS.Downloader.AP and Trojan.LNK.KS.  Both show up in the same place: C:\Users\User\AppData\Local\Microsoft\Outlook\m.hoyer@wippell.com.ost ; one as (INFECTED_JS and the other as INVOICE 17006632.

I see...I was thinking POS stood for something else. Don't see Point of Sale that often.

 

Go ahead and run the scans. Post the results, please.

Did you ever shop at wippell.com...stained glass...priest robes...halloween costume... :)?

.ost is an offline file designation for Outllook.

I've never personally shopped there, but I've helped a lot of people who have!  And do!

Why not just delete those files?

 

Please continue with the other scans before doing that, though.

ESET found no infections and thus left no log that I can find.

What about AdwCleaner's scan?

 

Have you given any thought to just deleting those files?

Haven't gotten to the AdwCleaner's scan yet.  For some reason, my employer expects me to take phone calls ... and stuff.

 

I'll run that and get back to you.

Just a heads up. Recently dealt with an infected OST file at one of our clients. Ended up removing the infection which in result messed up the outlook file which in return also messed up her emails. So I ended up having to restore the OST file. And going through the emails that had the Flagged extensions in them that it was picking up.
