Could you please try below steps and let us know the status,
I,m using Vista Service pack 2. The reset defaults didn't work but the turn off of Netguard did. Do I want to lose this safeguard on a permanet basis or just when I'm downloading or playing Adobe Flash.? Thanks for your help
I would suggest to turn off Netguard, only when you try to download or play using Adobe Flash.
Also you may check on Net Guard drawer and remove if there is any IP address added in blocked list and that may be helpful.
