Fast Browser Safe Search Hijack Trojan

Recommended Posts

MBAM didn't block Fast Browser PUP which displaced Firefox and Chrome and added links to social media on taskbar two days ago. These appeared to be quarantined but not removed on restart. Today it found them all again (logs reproduced below).

Arntz's article on  of 16/10/2015 said that should work but didn't.  https://blog.malwarebytes.org/cybercrime/2015/10/efast-browser-hijacks-file-associations/


Does anyone have any other suggestion? Should I be returning to Malwarebytes to delete these files an settings somehow?

Hello and :welcome:


We can use some tools to see how it returns.

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.

Let me know if this fixed your issue:


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 finished FRST will generate a log on the Desktop, called Fixlog.txt.

Please upload it to your reply.

Will this work if FRST and fixlist are both in download folder? I somehow started it after fixlist downloaded.

It seems to be mostly deleting temporary files including strangely McAfee error logs.  Occasionally it says "not responding " but seems to recover and continue . I hope it doesn't affect performance as I have limited experience to revive it beyond a restore point I guess.
