A group of cyber criminals is attempting to con Windows users into letting them access their PCs remotely, according to recruitment consultancy IntaPeople.
The scammers are calling users from a London telephone number, claiming to be from the Windows Support Centre and offering to remove viruses from their computer remotely.
Rob Samuel, IT manager at the firm, was contacted by the bogus Windows support team recently.
"Individuals should be on guard for any unexpected phone calls of this nature. It might sound legitimate, especially if you have been suffering from a virus around the same time as the call, but error reports would never be submitted to external sources and chased up in this way.
"Once the group has gained access to the user's machine, they will undoubtedly look to extort as much valuable information as they can."
