how do you get rid of adware in safari that creates hyperlinks to product websites?

I use thepiratebay.se and utorrent and I'm afraid somehow I've let adware screw up my safari broswer. I have a website www.lucidocopper.com and I have noticed several words are now hyperlinked to 3rd party's product websites. Now I'm afraid it's affecting the uploading of pictures to my website. I have not downloaded anything and I'm not sure what to do. I'd deleted all unknowns from application folder and all wondershare files from my finder. Are there any anti adware or anti virus software for mac to install to protect me in the future and ferret out the issue?

Cheers!
