Hi.  I currently have McAfee Security on my PC but was wondering if the Spyware Doctor with AntiVirus is any good to use as well for added protection.  Does anyone know about this and if it's any good?  I use to have Webroot Spy Sweeper on my computer but after a while it conflicted with McAfee so was just wondering if anyone knew of this product and if it is a good idea to use also.  I heard that added protection won't hurt you only help.  Thanks for any opinions.  I have a Dell Inspirion 530S with Windows XP Professional
