Homes and businesses in south Devon (even those who are ex-directory) are receiving phone calls from scammers who claim to be working for "Windows", "Microsoft", "BT", "TalkTalk" or any of a number of other companies and they claim that you have a computer problem.
At this stage they do not even know whether you actually have a computer or not.
If you admit you have a computer they will re-inforce their message by getting you to open the computer's Event Viewer pointing out error messages.
Most computers have such messages even when working well. They will then want to remotely access your PC to "fix it".
If you allow them remote access they could steal and then delete your confidential information, documents, email and photographs. They could also leave keylogging programs or even damage your operating system.
They will demand a card payment in an excessive sum. They may further lure you with an offer of several years cover by an anti-virus program which is a free one anyway.
ALWAYS HANG UP
If they nearly hooked you in they may well phone back. They may try to frighten you by saying you are causing a problem for others on the Internet or that you will be in trouble with your Internet Service Provider.
IF YOU HAVE FALLEN FOUL OF THIS SCAM PHONE ME IMMEDIATELY AND I WILL EXPLAIN WHAT STEPS YOU NEED TO TAKE.
