I'd like to reassure you gillybob. I have had these several times, and, although it was frightening the first time, now it just makes me laugh! They will probably got hold of an old password from years ago. The porn site thing is just a frightener! I have never accessed any porn site and nobody has had access to my laptop, so on reflection, I knew they had to be kidding. I rang actionfraudalert.co.uk and a very nice young woman talked me through what to do. You don't need to alert all your contacts, and you probably don't need to change all of your passwords (though do make sure that any new ones are 'strong'. Next, forward the message to [email protected] then DELETE the message and FORGET about it! I just forward all scams to [email protected] immediately now; you know, all the ones offering to deposit millions of dollars in your bank account if you give them your bank details
They are just 'phishing' - never send any money or supply any details. Just forward to the fraud bureau and forget!
