safari and firefox now crash immediately on launch in yosemite 10.10.1 my browsers started crashing immediately on launch on my late 2012 mac mini.

i reinstalled yosemite 10.10.1 again, and for a whole day, safari behaved perfectly. then both browsers started crashing again.

i reset PRAM, installed latest java, ran virus check, but no dice.

any solutions to this found?
Genieo Adware is installed.  Removing it will help.
  
  If you have another browser installed, use it.
     If not, launch App store and get another  browser for temporary use.
     Remove it afterwards.
  
  
  Use  free  AdwareMedic by clicking “Download ” from here
  
  http://www.adwaremedic.com/index.php
  
  Install , open,  and run it by clicking “Scan for Adware” button   to remove adware.
     Once done, quit AdwareMedic by clicking AdwareMedic in the menu bar and selecting
     “Quit AdwareMedic”.
  
  or
  
  Remove the adware  manually  by following the “HowTo” from Apple.

  Safari > Preferences > Extensions
      Turn those off and relaunch Safari to test .
      Turn those on one by one and test.
