Something is wrong with my BING system PLZ HELP

Ok i have this new laptop like 5 months ago. And ever seance My Dad took of the virus on it...bing has been looking things up like "im feeling luky" on google. Example, I once searched, Who is Hades" And instead it searched, "fat fails" *lol* but really its not ALL THE TIME but sometimes it does this. Im REALLY getting scared cuz its been lately looking up things inappropriate like,
"naked,hentai,and other BAD stuff. Im really scared because my parents will think I looked these things up!!!!
ive googled this up before and it doesnt help! bing is the only thing that does this. HAS THIS EVER HAPPENED TO YOU!! IM REALLY SCARED MY PARENTS WILL MISUNDERSTAND!!!!!!!! T.T
