Clicksor infestation in Firefox / Linux
I always thought that Linux was immune to this sort of thing, but I've gotten an infestation of the Clicksor malware. When I bring up a page in Firefox from some websites (not this one, fortunately), it highlights words that it recognizes and then trots out a popup referencing that word and leading to a junk website. I've also had this problem in Chrome. How can I make that nasty beast go away?
