So wd5dhk, you've had the call 3 times. I lost count ages ago. I have tried leading them up the garden path, pulling out my ethernet cable first so that things wouldn't go according to the caller's plan; patiently explaining that I am a computer professional (retired) and that I do know what he is talking about (ie tosh); tying them up in knots technically; etc, etc. Other times I will ask them to put document their concerns and evidence in writing and post it via snail mail so that I can weigh it up sensibly. Now I just say 'No thanks' and put the phone down. However they don't take the hint and keep on trying. I like NSDCars5's suggestion of giving them a Linux distro to play with.
It is interesting to see that they are trying to take on Macs.
The call I got today is a new slant. This time they pretended to be my internet service provider, BT, instead of from "Windows". The caller was obviously trying things out because he started coming out with terms from an old script and getting muddled. He didn't believe me when I said, no, my computer is not slowing down, and suggested that internet problems and downloads were the cause.
The interesting thing with this one is that on 09Nov13, didn't make it round the bend in the road and slammed into the telegraph pole, thereby severing comms to the neighbourhood. When pole was replaced and service restored 12 days later, I quickly found out that the broadband speed was well below par at about 55%. I waited a week to see how it rebalanced to no avail and so I complained to BT call centre. Question : has there been a leak in the call centre ? It seems suspiciously like it. Has anyone else out there had such suspicions ?
