Can someone check to see if I got a computer nasty?

Fucking hell. They are in other browsers and this is only on Yahoo. A shark has been jumped. I was kinda hoping my computer was infected before Yahoo got this bad.

@johnpowell I get those green lines from time to time… your not alone.

Thanks for the confirmation.

I don’t see them when I go to the page.

I’m using Firefox with Adblock Plus.

I do get them. I’m using Firefox on OSX 10.9.2, but don’t have any add-ons or extensions.

I use Google Chrome with Ad Aware and I have so far been devoid of annoying pop-ups, etc.

Also OS X 10.9.2 and Firefox. I am using Ad-Block Edge.

I get these in Safari too. I just booted into my back-up that still runs 10.8 and still got them. WTF yahoo?

I don’t know if this is a relevant factor, but my Firefox version is 27.0.1.

That is the current version. Good on you for browsing safe.
