Downloaded YTD downloader, got big malware/adware issue

Downloaded YTD Downloader, and ran the dmg, and all of a sudden I got all this "Spigot" and "Ebay" stuff attached to my browsers. It changed my background, changed my search from Google to Yahoo, and clearly affected my mac.

I deleted and re-installed both Chrome and Firefox, then I deleted all the "extensions" it made in my browsers and also in Chrome it had "Key Access" and there were things in there it had made and I deleted those as well. Things like "Itunes Ad" and "Spotify Ad" , we're all in the same timeframe as when I downloaded and ran this YTD Downloader program.

I ran Clam, Sophos, and one other free virus protection recommended and it only found 1 Trojan from awhile back, nothing from March 6th when I got this virus.

However, my Google Chrome still says this when typing in "www.google.com"

"https://www.google.com/?gws_rd=ssl"

And I feel like that means it's re-directing me somewhere and Firefox does not seem to do that, but it does seem to pop up with a big URL first then shrink down to the normal URL which seems out of the ordinary but I'm not sure...


Anyone have any recommendations or other virus/adware things to check out? Thanks!
