I installed SpwareBlaster 3.1 about a week ago and it installed and ran fine. Yesterday, I attempted to open the program to check for updates, and received an error message: "The program has been damaged, possibly by a bad sector of the hard drive or a virus. Please re-install it." I uninstalled and re-installed several times and kept getting the same error message. I am currently running Norton to see if it finds anything, but I am not very hopeful. I also run Ad-Aware, Spybot, and SpywareGuard, and none have been able to disable two persistent problems I am having. First, this annoying c1dcon popup that is somehow associated with Yahoo mail. Second, I have a frequent attempt to change my homepage etc., that SWG is able to stop at the time, but none of the programs seem able to remove. Any advice on these subjects would be greatly appreciated.
