Just FYI, Google Chrome flagged Videosift with the red NOT SAFE WARNING.

The website at videosift.com contains elements from the site cuitab.com, which appears to host malware – software that can hurt your computer or otherwise operate without your consent. Just visiting a site that contains malware can infect your computer.

I can confirm whatever was in the cuitab.com ad banner launches java which uses exploit to launch acrobat which has vulnerability to install lots of malware. I personally have java firewalled off from internet and uninstalled acrobat a long time ago as it seems most websites can infect you from the pdf exploit.
