323395 need web based proxy site

I need a web based proxy site that is similar to [login to view URL] except I need it to be disguised as a internet search engine. I wish to use this browser while I am at work. My job blocks specific websites like personal email, myspace, facebook, twitter, youtube and other social sites. It would be nice if it would have a discrete "get back to work" icon to open another application or webpage if the boss is near. I need this website to be able to bypass anything [login to view URL] might have in place counter the site. maybe mask the potential website's script so it cannot be identified as a proxy website to websense. Would operate on windows based computers.
