js.js. from pixel.mathtag.com

Recommended Posts


When visiting one particular website, my dad has started getting the popup do you want to open or save js.js. from pixel.mathtag.com 

He has a Windows 7 PC and is using Internet Explorer.

He is using the latest installation of Malwarebytes with latest updates. Malwarebytes does not detect any issues.

Can anyone please advise what action he could take.

Thank you

Hello and :welcome:


Please download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. 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.

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press Scan button. 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 makes also another log (Addition.txt). Please attach it to your reply.

FRST.gif Fix with Farbar Recovery Scan Tool

icon_exclaim.gif This fix was created for this user for use on that particular machine. icon_exclaim.gif

icon_exclaim.gif Running it on another one may cause damage and render the system unstable. icon_exclaim.gif

Download attached fixlist.txt file and save it to the Desktop:

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

  • Right-click on FRST.gif icon and select RunAsAdmin.jpg Run as Administrator to start the tool.
    (XP users click run after receipt of Windows Security Warning - Open File).
  • Press the Fix button just once and wait.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
  • When finishes FRST will generate a log on the Desktop, called Fixlog.txt.

Please attach it to your reply.


How is your computer behaving now?

Thank you again for the fast response and clear instructions. 

I used to work in IT at a bank. We were very cautious about distributing any system logs to any external party. Erring on the side of caution about personal details being uploaded to the internet, in the FRST.txt & Addition.txt that I uploaded, I had changed the PC name and the account logon names.

As your message says the fix was created 'for this user for use on that particular machine' I wonder if I've screwed this process up. Apologies if I have. Since the fixlist.txt doesn't mention PC name or account logon names, hopefully I haven't. Please confirm if I change the PC name and account logon names in FRST.txt and Addition.txt back to what they should be and run FRST with the fixlist.txt will that be OK?

Thank you
