Locked icon laccdb FoxPDF Accdb to PDF Converter 3.0 trojan

Recommended Posts

I was organizing my desktop on Win 10.   Suddenly a file/folder  changed or popped up as an  laccdb icon with  red lock.   This is an access database lock file. When I opened it there was an icon for a file that I had to click (in access) that took me to a screen to grant permission, which I did.  When I went back to the access file list an icon appeared unkn.pdf.accdb was present. When I clicked it access gave a warning it had active content.  I contacted microsoft and some idiot told me to try to open it, and there was nothing in there despite showing a size of around 560k.   The lock file on the desktop showed around 64k size.  


So, suspecting it was a pdf file that was converted into something else I wanted to restore the desktop file to its prior state.  Nothing doing, so I downloaded FoxDF Accdb to PDF Converter 3.0.  Installing it appeared suspicious in that the installation screens were not crisp appearing and a truncation appeared to occur, so I tried it again.  I wanted to get whatever I had back.   The FoxPDF converter did not work, and I don't know what it did.

Here are my concerns, I have never used access and do not use it, so I did not create a locked database.  The reason for locking it is to keep others out of it, in my case the other was me.   Today I tried to download Fox PDF Converter again but  Malwarebytes blocked it as a Trojan.   Don't know why Malwarebytes did not catch it yesterday afternoon.  So having deleted it I could not send it to VirusTotal.

I request help in (1)  correcting whatever payload, system changed and damage occurred from downloadind by Fox ,and  (2) recovering whatever data or file or folder was converted to the laccdb icon on my desktop, and (3) if this program harvested data and sent it somewhere where it went.


Lately, whenever on Facebook to play WSOP  (free poker game) my computer starts to freeze up and the hard drive goes very fast.   This does not happen on Facebook otherwise, and it doesn't happen elsewhere.   The only way to cool down the hard drive is to disconnect from the internet, so again it seems someone is hacking while in the play of WSOP to cheat, or is using WSOP in facebook as a method to gain unauthorized access to the computer for other purposes (such as looking for confidential or account information).   Also when this happens you lose your WSOP chips and have to buy more.    It happens dozens of times per session

I've run several scans none of which have detected the cause of this.


Help solving these problems would be appreciated.

Hello @juliegabby


Please run the following steps and post back the logs as an attachment when ready.
Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans are completed.
Temporarily disable Microsoft SmartScreen to download software below if needed. Make sure to turn it back on once the scans are completed.
If you still have trouble downloading the software please click on Reveal Hidden Contents below for examples of how to allow the download.



When downloading with some browsers you may see a different style of screens that may block FRST from downloading. The program is safe and used hundreds of times a week by many users.

Example of Microsoft Edge blocking the download






  • If you already have Malwarebytes installed then open Malwarebytes and click on the Scan button. It will automatically check for updates and run a Threat Scan.
  • If you don't have Malwarebytes installed yet please download it from here and install it.
  • Once installed then open Malwarebytes and select Scan and let it run.
  • Once the scan is completed make sure you have it quarantine any detections it finds.
  • If no detections were found click on the Save results drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If there were detections then once the quarantine has completed click on the View report button, Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If the computer restarted to quarantine you can access the logs from the Detection History, then the History tab. Highlight the most recent scan and double-click to open it. Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If Malwarebytes won't run then please skip to the next step and let me know in your next reply that the scanner would not run.


Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

  • Double-click to run the program
  • Accept the End User License Agreement.
  • Wait until the database is updated.
  • Click Scan Now.
  • When finished, if items are found please click Quarantine.
  • Your PC should reboot now if any items were found.
  • After reboot, a log file will be opened. Attach or Copy its content into your next reply.

RESTART THE COMPUTER Before running Step 3

Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

  • Double-click to run it. When the tool opens, click Yes to disclaimer.
  • Press the Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here each time
  • Please attach the Additions.txt log to your reply as well.
  • On your next reply, you should be attaching frst.txt and additions.txt to your post, every time.

I'm sorry, but at this point the best thing you can do is quit wasting your time on this build of Windows. Once you've used this approach to fixing Windows you've already compromised it even more in my opinion.

Back up your data to an external drive. Then format the hard drive and do a CLEAN install of Windows. You are going down a rabbit hole of problem after problem at this point. It quite literally takes less than 30 minutes to reinstall Windows.

It takes more time getting prepared by backing up your data and then after reinstall setting up customization and other program installs, but in the end you'll have a much better, safer running computer. Then look at doing imaging back ups so that if something happens in the future you can restore Windows as it was within minutes.
