We are living in a world in which we have to be vigilant regarding criminals who try to scam us. These criminals contact us via email and telephone. In some instances, their pitches are very intelligent and logical and, if you've been having computer problems for a month, for example, and you get a phone call from someone claiming to be a techie who does outsourced work for Microsoft, you might be tempted to allow him access to your computer. DON'T! A legitimate techie won't initiate a call to a potential client and Microsoft never initiates calls to clients or potential clients.
