No matter which browser I use, safari, chrome, firefox, the automatic search engine is yahoo which I be believe is a possible virus. It looks like for roughly 2 seconds it generates a google search and then automatically switches to yahoo, I went into my preference settings and set each browser to google and turned off "include search engine suggestions". I do not know what is causing this.

Please read Removing "Search Marquis" / "Search Baron" / etc on your own - Apple Community and post the three screenshots it describes in a reply to this Discussion.
It is written specifically for Safari but its basic instructions can be adapted to any browser.
So you are being redirected to yahoo search engine each time? First thing i would do is clear your browser history and website data....
On chrome: click 3 dots next to profile picture > history > clear history
On safari: click history within the menu bar > clear history... also on safari > safari menu next to apple log > preferences/settings > privacy > manage website data > give it time to load > remove all
Also download and run malwarebytes to check for any malware
