A few weeks ago I received an email from a trusted friend, saying I was invited to an event.  I clicked on the link, and attempted to log into the site with no success.  Regardless, it seems like a virus was attached to the email and replicated itself to all contacts associated with the email account.  I’ve heard from a number of people who received “invitations” from me, and were unable to log into to see the (nonexistent) event.
Any suggestions how to rectify this?  Many thanks.
