Had 20 minutes on the phone with a buy my malware cleaner/steal your credit card details bod, who was quite convinced he had someone worried about the supposed threat that he was waffling on about.  by sheer chance I had picked the phone up, managed to get him to give me his phone number on the grounds that I'd left my walet elsewhere so I'd ring him back. so pulled the pay as you go phone out, so if its a route to somewhere expensive number, checked I was still talking to scammer, then spun the conversation so he suddenly found himself looking down the barrel of someone who knew what they were talking about. he finally started panicing and put the phone down on me when I told him I was keeping him on the phoneline while the computer crimes unit checked that he was where he said he was and to expect a knock on the door very soon. :)

Any idiot can face a crisis - it's day to day living that wears you out.
