If the message says something along the lines of this action has been
prevented by an administrator, etc then maybe you used an internet
protection package such as one for spyware or malware to lockdown your
computer to secure it from hijacks etc. If you have installed or configured
such a program as of late that may be the problem. Some of these programs do
not make it clear to the user when they are being installed what they all
do. If you have not done anything like that then maybe you are a victim of
spyware or malware and should scan your computer for viruses with your
antivirus program being sure to use the latest definition file from your
publishers website. For spyware I suggest that you start with AdAware SE
which has a free for personal user version. To minimize the noise that it
will detect be sure to clear your cookies and temporary internet files
before scanning with it and make sure that you are using the latest
definitions for it before you scan. It should check for such during
installation. --- Steve
