I lately installed Norton on my MacBook because my college requires me to have it on my computer or they won't let me use it at the school. then i started having a minor problem with my monitor and posted some threads on apple's support page and some other sites. so far almost everyone has replied saying that norton does some really bad stuff to macs!!! how bad is it to have Norton running on a mac? and why would my college have me download it on my mac if it causes so many problems?
