SIR – Please be aware that ‘Michael’ from ‘Dell’ is targeting people via phone calls regarding their computers, which he emphasises are corrupted.

I took a call from him last week regarding this, but a few years ago I was almost drawn into this scam. I did log onto my computer at that time, but smelled a rat. After rejecting last week’s phone call, two days later we received NINE calls from him. Nobody, unless they have been invited by you to access your computer for repair work (which can be done remotely), should be phoning you to say that there is anything wrong with your computer. Be on your guard.
