The Gorse Fox is normally a trusting individual. This, however, does not extend to his various interactions on the web. So it was that the Silver Vixen came to his study with her MacBook which had an error message and a verbal warning regarding a virus.
First warning sign is that the Gorse Fox has an anti-virus program installed on the Silver Vixen's machine. Second warning sign was that it asked her to phone an 0800 number to get help to remove it.
The Gorse Fox hit google and sure enough found that it was a scam which was probably part of the payload in some Ad. He followed the instructions on the Apple website and the problem seems to have gone away. He's now running a full anti-virus check to satisfy his innate paranoia. He wonders how many people would have been caught out by this... it was quite convincing.
