Hello @joeoptics and :welcome:


Please run the following steps and post back the logs as an attachment when ready.


  • If you're already running Malwarebytes 3 then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
  • If you don't have Malwarebytes 3 installed yet please download it from here and install it.
  • Once installed then open Malwarebytes and check for updates. Then click on the Scan tab and select Threat Scan and click on Start Scan button.
  • Once the scan is completed click on the Export Summary 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 on your next reply.


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

  • Right-click on the program and select RunAsAdmin.jpg Run as Administrator to start the tool.
  • Accept the Terms of use.
  • Wait until the database is updated.
  • Click Scan.
  • When finished, please click Clean.
  • Your PC should reboot now if any items were found.
  • After reboot, a log file will be opened. 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.
  • Please attach the Additions.txt log to your reply as well.

Hi Joe,

Please go to Control Panel, Programs, Add/Remove and uninstall all versions of Java. You're running compromised versions of those programs.

Next, please run the following fix.


Please download the attached fixlist.txt file and save it to the Desktop.
NOTE. It's important that both files, FRST or FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt). Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.


Thanks, Ron

Great, log looks good.

If at all possible I would highly suggest using the computer without Java as it is often compromised. If you really must have it then make sure you keep it up to date and remove old versions. Only install from the official website. https://java.com


How is the computer running now?

Are there still any signs of an infection?

A malwarebytes scan just finished and I see no change in the results as far as the PUP.   I was not seeing any issues with the machine other than this report from malwarebytes.  A good thing to get rid of infected Java's though.  Can you tell me what the indication in the log file is of infection, so I can take care of detection myself in the future?

Hi David,

The version of Java is the indicator that it's old and normally security updates are made on most updates.

Let's go ahead and reset Google Chrome.

Please follow the directions from the following topic

Then restart the computer and run a new Threat Scan with Malwarebytes and let me know if the detection is still there.

I have managed to get rid of the PUP by following instructions on this:  


 which suggests using both Malwarebytes and a program called HitmanPro.  I got a trial licence for the HitmanPro, ran it and the PUP has not reappeared after a reboot and 10 or 11 hours on-line.  One interesting side effect of running Hitman is that my Malwarebytes Web Protection was disabled and I could not re-enable it with the slide switches.  Malware bytes kept telling me to enable Web Protection (I have a Malware Bytes Premium licence, so it should work).  However, when I rebooted the PC, Malwarebytes came up normally with Web Protection enabled.

All, good if the entry is gone now. Difficult to say what caused the issue with it not loading web protection but as long as it's working after the reboot that should be good. On a side note I would highly suggest not relying any browser to log you in automatically. There is all kinds of malware and even security tools that can steal those passwords so easily without even trying. Know your passwords to all sites, don't share passwords with any other site. Don't use automated login processes if you can avoid it. Use a password tool like KeePass or similar.

Unless there is something else, we should be done here now.

Thank you
