__Summary
Using plugins like Flash and the -moz-opacity filter it is possible to
display the about:config site in a hidden frame or a new window.
By making the user double-click at a specific screen position (e.g. using a
DHTML game) you can silently toggle the status of boolean config parameters.
As long as the number of about:config parameters is unchanged (unlikely a
casual user will change them) you can move the parameter you want to the
specified screen position by using CSS.
You can also load about:config using the real player plugin and merged url
events. See the real producer documentation for details and merge a command
like "u 0:0:0:0.0 0:0:0:30.0 &&targetframe&&about:config"

-- NTBugtraq Editor's Note: Most viruses these days use spoofed email addresses. As such, using an Anti-Virus product which automatically notifies the perceived sender of a message it believes is infected may well cause more harm than good. Someone who did not actually send you a virus may receive the notification and scramble their support staff to find an infection which never existed in the first place. Suggest such notifications be disabled by whomever is responsible for your AV, or at least that the idea is considered. --
