I was using SBC Global while in California. I moved to Oregon and am currently using Comcast. The problem was that my anti virus was part of my SBC Global package. I was able to contact SBC Global where they informed me that they use Symantac which uses Norton anti virus. I was able to contact and download Norton uninstall tool to uninstall the anti virus. I also uninstalled the SBC Global software (AT&T Yahoo) and that enabled me to install new anti virus software.

Install the old anti virus 2005 and then the updates. or contact the anti virus company the would tell you what to do.
