Fake phone technicians are still on the loose, experts warn

Fake phone technicians will try to persuade the computer owner to install a piece of malicious software so they can steal data or install Trojan viruses.

The phone rings and it's someone claiming to work for Microsoft. They tell you there's a virus on your computer and offer to remove it. If this happens to you, hang up immediately – the caller is almost certainly a fraudster. 

They will probably try to persuade the computer owner to install a piece of malicious software so they can steal data or install Trojan viruses. They might be looking for bank account details – or they might even lock the computer and demand a fee to unlock it.
