So, I helped someone the other day who had recently been scammed by a company into paying for a copy of Microsoft Security Essentials, and who then used remote desktop to install it.
But that wasn't the worst of it. They had also installed a key logger to capture his passwords, compromising his email account, which is a secondary mess this customer will now have to deal with.
Now, there are a lot of computer problems that can be solved by technicians and software, but nothing is more power or helpful at keeping your computer and personal identity safe than keeping yourself informed. If someone calls and starts telling you how badly your computer is infected, ask yourself, "how does he know how many viruses my computer has?" And if someone you didn't hire starts telling you you need to let them install a new program, question that, too. Hop on Google real quick and look up the name of the company, or even the software they are peddling, it may just save you a lot of money and heartache in the end.
