The newest Firefox browser has a spell check built in, though it's not the greatest but it helps a lot. Go to
Mozilla.com and follow the links to get it. Firefox is much better than internet explorer anyways because it is simpler and 999999999x safer. I have not gotten a single bit of spyware or a virus since installing and using it. Unfortunately, you never can get rid of old IE, but there are some sites, such as FTP's that can only be accessed by IE. (FTP=File Transfer Protocol I think, basically its an online file storage for websites, or a digital hard drive)
