This is a year old, but seems to be resurfacing again .... just a word of caution
I had it happen to me a few months ago.
This virus will be received from someone you have in your address book
If you receive an email called: "Invitation FACEBOOK,"
though sent by a friend, do not open but delete it immediately
CNN said it is a new virus discovered recently
and that has been classified by Microsoft as the most destructive virus ever.
It is a Trojan Horse that asks you to install an Adobe flash plug-in.
Once you install it, it's all over.
There is no repair yet for this kind of virus.
This virus simply destroys the Zero Sector of the Hard Disc,
where the vital information of their function is saved.
Again, just a word of caution
