on every page i visit now (in chrome) random words are highlighted (you know the way on some sites keywords link to ads), usually leading to an ad for an ipad or something. as in, some of these words i'm typing right now will be highlighted (on my browser).
i've ran some scans and it hasn't got rid of the problem. ideas? i was messing around with chrome 'under the hood' recently to increase the font on chrome, if that might have anything to do with it.
