Can't open links in e-mails
Suddenly my computer is refusing to open links (eg to a youtube clip) that have been received in an e-mail.
The message reads "this operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator"
As this is a personal domestic PC there is no administrator but me, and I haven't touched anything, honest! I also have no idea how to fix it.
Baffled again.
