Can't get on pages with ads - gets moved to a search page

Hi there - I recently got a new computer at work and it worked fine for a few days then quit allowing me to go to any type of site with an an, such as hotmail, any news pages, etc. I get diverted to the dell search site (it's a dell laptop), with tribulfusion or any other number of web sites to go look to for assistance (thanks but NO thanks!)

I have ad- aware, spy sweeper, Microsoft Defender and Spy Bot - they found cookies and some other things but obviously something is loading each time the computer starts up. Here is my hijack log:
