Have I been infected?


Recommended Posts

Hello

I seem to be getting of these alerts the last couple of days, is this something to be concerned about? Or could it be an issue with a Firefox addon?

Hello mo2k20 and welcome to malwarebytes....

Continue with the following:

If you do not have Malwarebytes installed do the following:

Download Malwarebytes from the following link:

https://www.malwarebytes.com/mwb-download/thankyou/

or,

https://downloads.malwarebytes.com/file/mb4_offline

Double click on the installer and follow the prompts. If necessary select the Blue Help tab for video instructions....

When the install completes or Malwarebytes is already installed do the following:

Open Malwarebytes, select > "settings" > "security tab"

Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....

Go back to "DashBoard" select the Blue "Scan Now" tab......

When the scan completes quarantine any found entries...

To get the log from Malwarebytes do the following:
 
  • Single click on the target sight above scanner window.
  • In the new window select Report
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply

Next,

Download AdwCleaner by Malwarebytes onto your Desktop.

Or from this Mirror
 
  • Right-click on AdwCleaner.exe and select user posted imageRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users)
  • Accept the EULA (I accept), then click on Scan
  • Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Quarantine button. This will kill all the active processes
  • Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it
  • After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply


Next,

Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status...
 
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"

Hello mo2k20,

Continue please:

 
Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file when running FRST fix"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

Download Sophos Free Virus Removal Tool and save it to your desktop.

If your security alerts to this scan either accept the alert or turn off your security to allow Sophos to run and complete.....

Please Do Not use your PC whilst the scan is in progress.... This scan is very thorough so may take several hours...
 
  • Double click the icon and select Run
  • Click Next
  • Select I accept the terms in this license agreement, then click Next twice
  • Click Install
  • Click Finish to launch the program
  • Once the virus database has been updated click Start Scanning
  • If any threats are found click Details, then View log file... (bottom left hand corner)
  • Copy and paste the results in your reply
  • Close the Notepad document, close the Threat Details screen, then click Start cleanup
  • Click Exit to close the program
  • If no threats were found please confirm that result....

The Virus Removal Tool scans the following areas of your computer:
  • Memory, including system memory on 32-bit (x86) versions of Windows
  • The Windows registry
  • All local hard drives, fixed and removable
  • Mapped network drives are not scanned.


Note: If threats are found in the computer memory, the scan stops. This is because further scanning could enable the threat to spread. You will be asked to click Start Cleanup to remove the threats before continuing the scan.

Saved logs are found here: C:\ProgramData\Sophos\Sophos Virus Removal Tool\Logs

Let me see those logs in reply, also tell me if there are any remaining issues or concerns..

Thank you,

Kevin.

Thanks for the clarification on the fixlist Kevin.

FRST did an update of somewhat when I loaded it this time, also Windows had downloaded an Update and that was applied when I restarted, hopefully that won't mess with the results.

Have attached the FRST results, I am running the Sophos tool now.Fixlog.txt

Even with the scans running (firefox was open sorry), I had a hit from MWB Premium for the outbound connection.

I will try and run Sophos with Firefox closed in case it interfered with the results. Difficult as it's my main browser!

Hello mo2k0,

As Sophos returned a clean log I believe the problem you have is only associated to Firefox. The best way forward is to make a fresh clean install of FF and see if that clears the issue:

Make a "Clean" install Firefox:

Use the following link for instructions how to back up your bookmarks, same link can be used to import saved Bookmarks:

https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer

To manage Passwords :-

https://support.mozilla.org/en-US/kb/password-manager-remember-delete-change-and-import

Next,

Remove all synced data from Firefox to stop possible re-infection or exploitation.

https://support.mozilla.org/en-US/questions/1037353

Next,

Go here: http://www.mozilla.org/en-US/ download save the latest version of Firefox.. We will install this later...

Next,

Lets totally remove Firefox and start over.

Go here: https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer and follow those instructions...

Ensure when the uninstall completes to navigate to and delete the firefox installation folder (if present):

(32-bit Windows) C:\Program Files\Mozilla Firefox
(64-bit Windows) C:\Program Files (x86)\Mozilla Firefox

It is essential the installation folder is removed. Re-boot your system when that is completed....

Next,

To remove all remaining data and profile information...

Press "Windows key + R" to open the Run box
In the Run box, type in or copy and paste %APPDATA%
Click OK. A Windows Explorer window will appear.
In this window, choose/open in succession Mozilla > Firefox > Profiles.
Select Delete on each entry in reverse, eg Profiles > Delete. Firefox > Delete. Mozilla > Delete.

Re-boot your system when complete!

Next,

Use the Mozilla Firefox installer to reinstall your Browser....

When Firefox is installed and open select these keys together :- Ctrl - Shift - A that will access Addons manger, this gives access to find addons/extensions, use, start, stop or disable those features etc....

uBlock-Origin can be installed from here: https://addons.mozilla.org/en-GB/firefox/addon/ublock-origin/ <<--- Recommended.

Malwarebytes browser guard from here: https://www.malwarebytes.com/browserguard/
 
Do the blocks cease?
 
Thak you,

Hi Kevin

I did follow all these instructions, and re-installed Firefox but funnily enough when I reinstalled all my previously installed add-ons I had an immediate hit while updating uBlock-Origin (which was also an add-on I was using before).

So I looked into the URLs of the filters I was using, being precautionary I basically ticked every single ad-filter known to man on uBlock-Origin as default, so it turns out that the Latvian List is now hosted at notabug.org. Whether that's deliberate or been hacked I don't know, but basically unticking the Latvian list has stopped this issue occurring. I think all previous hits were just where Firefox was attempting an update of uBlock-Origin's filter lists, and this was being blocked by malwarebytes.

So I've disabled the Latvian List from uBlock-Origin for now (don't really browse much Latvian web lol), will update this if I have any further occurrences. Attaching a screenshot showing the Latvian List URL as it may help someone else in future, as you can see it's the only one that fails the download because Malwarebytes blocks the outbound connection:

Hello mo2k20,

Ive listed the associated url for notabug.org to VirusTotal and a clean bill of health is returned:

https://www.virustotal.com/gui/url/6b5322ae10243b9df2c720182490a76afe508b591fabc5b16e136bfe9fddb12b/detection

https://www.virustotal.com/gui/url/6b5322ae10243b9df2c720182490a76afe508b591fabc5b16e136bfe9fddb12b/details

This may very well be a false positive (fp) I`ll make enquiries regarding this issue...

Thank you,

Kevin..

Hello again mo2k20,

Notabug.org has been deemed to be not malicious so the alerts are indeed false positives, that alert will be cleared on the next update for Malwarebytes. I guess we can clean up, after that you should be good to go...

Uninstall the following program:

Sophos AV

http://www.askvg.com/how-to-completely-uninstall-remove-a-software-program-in-windows-without-using-3rd-party-software/

Next,

Right click on FRST here: C:\Users\Muhsin\Downloads\FRST64.exe and rename uninstall.exe when complete right click on uninstall.exe and select "Run as Administrator"

If you do not see the .exe appended that is because file extensions are hidden, in that case just rename FRST64 to uninstall

That action will remove FRST and all created files and folders...

Next,

Remove all System Restore Points: https://www.tenforums.com/tutorials/33593-delete-system-restore-points-windows-10-a.html#option2

Create clean fresh Restore Point: http://www.thewindowsclub.com/create-system-restore-point

Run Windows Disk Clean Up Utility - https://neosmart.net/wiki/disk-cleanup/

From there you should be good to go...

Next,

Read the following links to fully understand PC Security and Best Practices, you may find them useful....

Do I need a Registry Cleaner?
