“It seems that telephone scams are on the increase again. Typically the scammer may do something along the following lines: They will probably claim to be calling from Microsoft (Microsoft never calls anyone) to say you have a computer virus. They may offer to show you evidence of corrupted files or system errors, trying to persuade you to let them have access to your computer to put things right.”
Don’t on any account listen; don’t give them access – and certainly don’t agree to pay them anything.
Also, if you get any suspicious email messages, please bin them rather than open them. It’s better to be safe than sorry. There is a very useful website called Hoax-Slayer, where you can quickly check whether something is genuine or a hoax. You will find it at http://www.hoax-slayer.com/“
