Broken digital signature, issued by: Malwarebytes Corporation


Recommended Posts

Hello, I have an issue that's popped up twice on my AVG scan. It reads,

Threat: The file is signed with a broken digital signature, issued by: Malwarebytes Corporation.

Object Name: C:\users\owner\AppData\Local\Mozilla\Firefox\Profiles\4jlm5zh.default-1473997761617\cache2\entries\BC59AC20E6E93E9E53A3F4CFAD91A81FCE4BE379

Severity: Message

State: Notification

Identified by: Scan

 

Plus earlier today when I went to run MalwareBytes I received this message:

"Malwarebytes was unable to load the Anti-Rootkit DDA driver, this error may be caused by rootkit activity. Do you want to reboot the system and attempt to install the Driver? (If you don't choose to reboot, Anti-Rootkit scanning will be disabled for this session.)

 

What steps should I take? Should I uninstall my current edition of Malwarebytes and download a new one? Any steps and advice would be much appreciated. Thank you.

Hi @BelleCoeur and :welcome:

Not sure why it would be reading one of our files from the Firefox profile but let's go ahead and get some logs and see if we can figure out what's going on here.

 

Please download 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 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). Please attach it to your reply as well.

Hi Belle

Notice that your Event Logs are showing some errors with an Access Denied. I could be wrong but I believe this might be due to your installation of AVG. What I'd like to suggest is doing a full uninstall of all AVG software Then also do a clean removal and reinstall of MBAM and then reboot a couple times and let's see if those error are still present or not.

Thank you so much for all of your guidance and help! I really appreciate it. I've already noticed a huge great difference in how my computer and Mozilla is running now. I'm happy to report it's much faster and more back to normal!

Thanks for the logs, glad to hear things are running much better now. However the FRST and Addition logs are the old logs. Please remove those logs and restart the computer 2 times. Then run FRST again. Make sure you place a check mark in the Additions.txt check box and then attach both new logs again. Thanks.

As for the AVG please note that soon there will be no more AVG Avast Announces Agreement to Acquire AVG for $1.3B

You may wish to look at installing Avast antivirus if that is your choice of antivirus but please run the FRST log again, before installing antivirus. Once that is done, make sure you choose and antivirus and get it installed and updated.

Thanks again 

Ron

Thanks Ron!

Oh shoot, I apologize. I ran it again per the earlier instructions and thought it had started new logs. I've been a bit under the weather so hadn't had time to get back on my laptop but I will run them in the morning if that's ok. 

Wow, thank you for the Avast news! I'll look into them. 

Thank you again; I wanted to touch base here and let you know I got your message. Will post the new logs tomorrow.

The logs show you're running an old compromised version of Java (Java 8 Update 77). Please uninstall all versions of Java. If possible and you can do without Java that would be my recommendation as that software often gets compromised. If you really have to have Java then make sure you keep it up to date at all times.

All the even log errors you were having are now gone now that AVG has been removed, so yes that confirms they were due to AVG. However, you need to install some type of antivirus software for protection. It can be Microsoft Security Essentials or Avast, or any other well-known antivirus, but you need something.

Also, I cannot stress how important it is to have external USB backup of all of your important data. I highly recommend you read the following  Backup Software and if you're not already backing up then get an external USB drive and get started. Remember though, don't keep the drive connected all the time. Only when doing your backups and don't connect it if you think the computer may be infected.

 

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

 

Thanks

You're quite welcome @BelleCoeur

Here is a closing speech for you. Please review as you have time as it can help you to prevent future infection issues. If there is anything else I can do to assist you please me know.

 

At this time there are no more signs of an infection on your system.
However if you are still seeing any signs of an infection please let me know.

Let's go ahead and remove the tools and logs we've used during this process.

Most of the tools used are potentially dangerous to use unsupervised or if ran at the wrong time.
They are often updated daily so if you went to use them again in the future they would be outdated anyways.

The following procedures will implement some cleanup procedures to remove these tools.
 
bwebb7v.jpgDownload Delfix from here and save it to your desktop. (you may already have this)

  • Ensure Remove disinfection tools is checked.
  • Click the Run button.
  • Reboot


Any other programs or logs that are still remaining, you can manually delete. (right click.....Delete)
IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST folder, FRST-OlderVersion folder, MBAR folder, etc....AdwCleaner > just run the program and click uninstall.


 
If there are any other left over Folders, Files, Logs then you can delete them on your own.
 
Please visit the following link to see how to delete old System Restore Points. Please delete all of them and create a new one at this time.
How to Delete System Protection Restore Points in Windows 7 and Windows 8

Remove all but the most recent Restore Point on Windows XP


As Java seems to get exploited on a regular basis I advise not using Java if possible but to at least disable java in your web browsers
How do I disable Java in my web browser? - Disable Java

A lot of reading here but if you take the time to read a bit of it you'll see why/how infections and general damage are so easily inflicted on the computer. There is also advice on how to prevent it and keep the system working well. Don't forget about good, solid backups of your data to an external drive that is not connected except when backing up your data. If you leave a backup drive connected and you do get infected it can easily damage, encrypt, delete, or corrupt your backups as well and then you'd lose all data.
Nothing is 100% bulletproof but with a little bit of education you can certainly swing things in your favor.


If you're not currently using Malwarebytes Premium then you may want to consider purchasing the product which can also help greatly reduce the risk of a future infection.
