Lots of gnarly rashes going around. I've worked on a few computers lately that were riddled with icky's in every crevasse....mostly within browsers and redirects similar to what is indicated.

I did enjoy a story about a buddy dropping off his laptop last week saying "I have 2 kids and wife that's always home....I know it's not porn cause I don't have time for that". His browser history shows a different story. A much different, longer, a lot of browsing porn story.

On the bright side, you can still get this type of stuff from non-porn activities. I found another issue last week that was started from a CNET.com download. Completely jacked the browser after downloading a pdf viewer.

Some crap like this piggybacks on other software. Make sure you check (or uncheck) every box when downloading something.
