Leah~1125, Follow the Removal Instructions at the link below including the disabling System Restore and restarting your computer then run a full virus scan. There's also a link to a Removal Tool if needed. Once you get rid of it completely turn on System Restore again.
I am running Norton Corporate on my Windows XP but every time I go online, I get Beagle.J. The Norton window pops up once every time I go online whether I've opened Outlook Express or not. Where is this thing coming from and why does it pop up only once each time? Norton deletes it but then says Access Denied.
