utorrent messed with my browser settings among other things?
So I had downloaded utorrent yesterday but ended up not needing it like I did and I realized that it had changed my browser settings to go straight to Yahoo Search. I fixed the extensions and reset the browser home page and everything and continued on my day not thinking much about it and shut down my computer before i went to bed.
This morning though, I tried to turn on my computer and rather than an apple symbol coming up while it turned on, it showed a circle with a slash going through it. I did a reboot and managed to get my computer to turn on normally. I went to my browser and once again, Yahoo was coming up. I did a bit of searching and found out that with the utorrent download, it sets up the crappy yahoo search so I tried to uninstall utorrent (it doesnt give any uninstall option so i dragged everything i could find having to do with utorrent and put it in the trashcan and emptied the trash) but STILL, my browser is going straight to Yahoo. I can't figure out how to change it or find whatever it is that is on my computer that is making this happen and I can't find a proper answer anywhere else on the internet. I'm not sure if the computer startup problem is just a coincidence or if it is due to whatever was set up with utorrent. What can I do to fix the browser problem? could the start up issue be related? I'm afraid I might have a virus or something. Is there a way I can reset things to how they were 2 days ago when I didn't have this issue?
