If you regularly browse through the internet, chances are you’ve encountered a website that has been affected by a malicious advertisement. It used to be that you could somewhat predict what sorts of sites would have these problems (spammy looking and adult-oriented sites) but now the problem is more prevalent.
Readers of NYTimes.com learned over this past weekend that even the most respectable sites can be affected by rogue ads. Some visitors reported pop-up messages that instructed them to install a fake anti-virus software which, of course, is never a good thing. To help warn readers, NYTimes.com posted the following tweet: "Attn: NYTimes.com Readers: Do not click pop-up box warning about a virus - it's an unauthorized ad we are working to eliminate."
