Need help with infection: Android/Trojan.Spy.Spynote.jl377

Recommended Posts

Hi, I have just updated my Malwarebytes app and done a new scan and found heaps of infections relating to Android/Trojan.Spy.Spynote.jl377
I am getting pop ups saying "Malware detected. 1 infected file. org.malwarebytes.antimalware"  with an option to Ignore or Remove. 
Does this mean the Malwarebytes app itself is infected??  I'm getting the same pop up for multiple different files.  
Inside the app there is a list of detected malware files to be removed.  I removed one as a test and it uninstalled the entire app.
So I'm a bit nervous about just removing all the threats, some appear to be system files etc.  Would appreciate any advice about how to handle this.
I have logged a support ticket but thought someone may be able to offer advice in the meantime.
thank you

Hi @Annew,

Thanks for letting us know!  I think I resolved, but could you send us info?

Depending on what version of Malwarebytes for Android you are running, here’s how to send us the info to resolve.

Client 3.x.x — Send Apps Report

To send an Apps Report with Malwarebytes for Android use the following instructions.

  1. Open the Malwarebytes for Android app.
  2. Tap the Menu icon.
  3. Tap Your apps.
  4. Tap three lines icon in upper right corner.
  5. Tap Send to support

Client 5.x.x — Export diagnostic data

  1. Open Mobile Security on your mobile device.
  2. Tap Settings > General.
  3. Toggle on Enable diagnostic mode.
  4. Repeat the steps that led to the issue. Once the issue occurs, diagnostic mode records the incident.
  5. Return to the Malwarebytes app, tap Settings > General, then tap Export diagnostic Data.
  6. Send the diagnostic log to Malwarebytes.

Choose an email app to send Apps Report or Export diagnostic data.  If you used Export diagnostic data, you can now toggle off Enable diagnostic mode.

Your email app will open with the Apps Report or Export diagnostic data included.

At this point, it would be very helpful to mention you are submitting via recommendation from the Malwarebytes forum.  This allows our support staff to know where to direct it.

By sending, you will create a ticket in our support system.

Private Message (PM) me the email used and/or the ticket number assigned.

If I'm right, this will resolved in Malware DB 2023.09.15.03.  Give it an hour to replicate over all servers, then you can force update.

@mbam_mtbr thanks Nathan, will try again.  

I am not sure what you mean by updating the Malwarebytes client (as suggested via DM)  Do you mean updating from 3 to 5?   Is that just a matter of installing a different app? Is that something you recommend even if this issue is resolved?  I assume 5 has more features?  Does my premium subscription carry over to 5?   (I had forgotten I had premium but must have decided it was worth it! 😄)

Thank you

Preventing malware infections in the future:

  • Only download apps from trusted sources like the Google Play Store.
  • Avoid sideloading apps from unofficial websites.
  • Be cautious when granting app permissions.
  • Regularly update your device's software and apps.
  • Install a reputable antivirus or anti-malware app and keep it updated.

Remember that it's crucial to act promptly to address malware infections on your Android device to prevent further damage and protect your data.

Thank you, it turned out I didn't have an infection after all (thank goodness!)  I am always careful but appreciate the tips, doesn't hurt to be reminded :)
