There has been a number of incidents recently about cold-callers to business, and homes claiming to be from Microsoft, or various other large IT related companies, that report that you have a problem with your computer, such as viruses, or invalid software. They then ask you to goto a website, which will allow them to remotely control your computer.
If you receive such a call, unless you know the company, and/or the person calling as you have subscribed to paid technical support, or requested the support, please do NOT follow his instructions, and simply hang up.
Should you fall prey to any of these hoaxes, they may attempt to charge you themselves to fix it. DO NOT give them your money. Switch off your computer Immediately, and seek technical advice from someone you trust.
I’d also like to make you aware of a website becoming popular with young people at this time, called Chatroulette!
This site, although stating a minimum age of 16, has some highly questionable, and unsuitable material on it, and is NOT recommended that anyone uses this site. If you have any parental controls available on your computer, it is highly recommended this site is added to the block listings.
