Watch What You Click On

I have been using my son's laptop because mine is down.  I noticed when I get on here that there are random words on my web site that look like a link to a web site.  Please do not click on them.  They are not mine.  I usually point out a link I put on here.  Just a random word underlined is not me.  I won't click on them  because I am pretty sure it is a virus.  I don't know how to get rid of them so if you know, please let me know!  Sorry guys!
