We've got a virus warning on our pc and can't even open the internet any more to download one of the free anti virus programmes. Any ideas? We're pretty sure it's a fake warning, but it's now taken over our home page (the first window that opens when you start up the computer).
How can we get rid of it? (On my netbook at the mo, as the pc is completely out of use!

)
Thanks for any help.
