Malware In Ads
Quoted from the link:
I also want to encourage--actually, no, beg of you--to inform your friends about this if you haven't already, whether you're against ads on LJ or not, and tell them to do the same. Link to this post, or give all the needed information in yours. Yes, the ad has been pulled, but people you know may be infected, and if it's already happened with one ad, it might happen with another. This isn't an political issue about ads versus no ads, this is an issue about keeping malware off of people's computers, and people need to know.
