I accidentally clicked a strange screen saver yesterday. Immediately my Spybot program (1.6.0.30) began requesting registry changes which I denied. Now I am unable to run Spybot and my Foxfire browser re-directs me at certain times and downloads advertising. Especially at spyware information sites. I un-installed and re-installed Spybot but it still won't open. I downloaded and ran ERUN successfully. I downloaded HTJ install but it will not start the installation. I am running Mc Afee Virus Scan 7.0. My Windows XP firewall was not running. I have a 6 month old Dell desktop. Any suggestions?
