Back-up, Back-up, Back-up! If you're not already backing up your computer, you need to be, NOW.
Microsoft Windows has a built in backup utility. It's already installed on your Windows based computer, you just need to configure it.
There has been a recent increase in the amount of computer related phone scams going around. Here's what happens:
You get a phone call from someone claiming to be with Microsoft or just 'tech support'. They tell you that your computer is infected with a virus. They may even walk you through opening up the Event Viewer in windows to show you all the 'errors' being generated purportedly by the virus. That may look convincing, but don't let them fool you.
