Recommended Posts

@coryincanada

Check out the link below and hopefully Malwarebytes staff can offer some suggestions.

How to create a post for a PUP in Prefs.js

Also check this post as I think it might be more in the direction of the issue you are seeing.

PUP Conduit Reappearing

Since I already posted I will wait for the response till I attempt to eradicate the offending evil PUP.

I took a look at the logs and think my issue is WebCompanion - and have found some links for removing but, will wait for response to my original post.

Hello @MarkInTexas and :welcome:

You have some old compromised versions of Java installed. Please uninstall all versions of Java

Java SE Development Kit 8 Update 131 (64-bit) (HKLM\...\{64A3A4F4-B792-11D6-A78A-00B0D0180131}) (Version: 8.0.1310.11 - Oracle Corporation)
Java SE Development Kit 8 Update 131 (HKLM-x32\...\{32A3A4F4-B792-11D6-A78A-00B0D0180131}) (Version: 8.0.1310.11 - Oracle Corporation)
Java SE Development Kit 8 Update 161 (64-bit) (HKLM\...\{64A3A4F4-B792-11D6-A78A-00B0D0180161}) (Version: 8.0.1610.12 - Oracle Corporation)
Java SE Development Kit 8 Update 161 (HKLM-x32\...\{32A3A4F4-B792-11D6-A78A-00B0D0180161}) (Version: 8.0.1610.12 - Oracle Corporation)

I would not recommend the use of System Mechanic Professional. Windows 10 can already manage the majority of any type of maintenance  issues needed without the risk of further damage to the system.

Not sure if you're using Dropbox on the daily but the updater is out of date. If you're no longer using Dopbox then I'd recommend you uninstall it. If you are using it then look at updating it. The program itself is seems to be up to date but the updater looks to be old.

Also don't recommend the use  of CodecTweakTool. Back in earlier days tools like that were very helpful. Nowadays you just don't have anywhere near the same amount of video formats in use that we once had and you needed tools like this. Nowadays the vast majority of video files are mp4. Though you can still find other formats out there they are often very old files.

 

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.

fixlist.txt

 

Once that is done and the computer has rebooted please run the following scans again and let me know if you're still having any signs of an infection.

 

 

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

STEP 01

  • 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.

STEP 02

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 Now.
  • When finished, please click Clean & Repair.
  • 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

STEP 03
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.

 

Thanks

Ron

The Malwarebytes log found something but it says you did not choose to remove it.

PUP.Optional.Conduit, C:\USERS\MARK\APPDATA\ROAMING\MOZILLA\FIREFOX\PROFILES\7CWXGA15.DEFAULT\PREFS.JS, No Action By User, [215], [301520],1.0.8151

You may need to manually reset this to clear out that entry causing the detection.

Overall the logs look pretty good now. I would recommend you reboot the computer, then run a new Malwarebytes Threat Scan and ensure it comes back clean now.

How is the computer running now?
Are there any other signs of an infection now?

The following advice below should help you to reset any browsers as needed.

Please visit each of the following sites and let's reset all of your browsers back to defaults to prevent unexpected issues.
If you are not using one of the browsers but it is installed then you may want to consider uninstalling it as older versions of some software can pose an increase in the potential for an infection to get in.

Internet Explorer
How to reset Internet Explorer settings

Microsoft Edge
How to Reset Microsoft Edge in Windows 10

Firefox
Click on Help / Troubleshooting Information then click on the Refresh Firefox button.

Chrome
Reset Chrome back to defaults to completely clear out issues with Chrome.

  • Open Chrome and at the top right, click ellipse.png.2829aeeb2aea006bc956de077091and then More tools and then Extensions
  • Write down the list of Extensions installed.
  • Next, go to >> Google Sync << and sign into your account. Make sure you know your password as this will clear it from the browser.
  • Scroll down until you see the  reset_chrome_sync.png "reset sync" button to clear your data from the server and remove your passphrase.
  • Now, close all Chrome windows. Chrome cannot be running for the next step. If needed, print this information or use another browser to read the information.
  • Press the Windows key + R at the same time, to bring up the run dialog box.
     
    • run_command.png
       
  • Type in (or copy/paste) the following and press Enter:     %localappdata%\Google\Chrome\User Data\Default\
  1. Press Ctrl + A to select all the files and folders.
  2. Hold down Ctrl + A and click once on the files "Bookmarks" and "Bookmarks.bak". This will unselect them.
  3. With all the files selected (except for your Bookmarks), press the Delete key and click Yes to delete the files and folders.
  4. Example of all files and folders selected, except Bookmarks

Restart your computer now and make sure there are no longer any redirects or other browser issues and let me know the results

Thanks

Ron

Yes, and then repeated all steps X 3 and success!

Ran MB,  ADWCleaner, FRST, Reset FF, Rebooted x 3 times.

on 3rd time removed Ad Block (not Ad Block Plus) had 2 Ad Blockers running anyway.

Cannot say 100% it was AdBlock but problem gone after removing.

https://getadblock.com/

After 3rd round and removing Ad Block MB detected no issues!

Here are logs.

BTW, It would be REALLY nice if MB would indicate what line(s) in Prefs.js that are flagged as possible issues.

 Thanks for the help.

Addition.txt 

 

AdwCleaner[C04].txt

FRST.txt

mb.txt

Agreed, I looked at my own file and could see where it would be hard to determine. I was going to ask you to zip and send me the file but since you've got it cleaned now, no need.

Is there anything else I can assist you with at this point then? Things appear pretty good in the logs

Shoot, I meant to save one that had it and one that did not and compare the files. But forgot to do that.

Could you submit a feature request to add more detail when something found in a file such as Prefs.js.

But no, thanks for the help.

Till next time...

(Close this thread, we are good.)
