Getting Around Company Web Blocks

My computer at work will not let me use any email such as Yahoo or Google and I can’t visit pages such as Netflix or the New York Times. There are Symantec blocks on it. I figured out that when I use a friend’s AOL account it gets me around theses blocks. But I really don’t want to have to pay a fee to join AOL. Can anyone think of a free program I could sign into to get around the Web blocks on my computer?

Thanks.
