I dunno if you're already aware of this, but McAfee SiteAdvisor, a piece of software that people install on their computers to prevent them from accidentally visiting sites that install adware, trojans, phishing, etc. blocks 2+2. Apparently, because you can download Everest Poker's software from the site. This is obviously retarded, and though I've left a message on their website, as the site owners, you might want to contact them and let them know how and why this is stupid.
You can see the details here:
