Virus: Nope Yourself: Generally, no.. Aunt Edna (she wanted to buy you a Christmas gift online, she doesn't have her own computer): Negative What I think the most dangerous thing to any computer is nerdious falsius. nerdious falsius are hard to spot by the untrained eye. These people act like they know everything about computers, and the untrained eye is easily tricked, until after it touches your computer. The truth of the matter is these people know not much at all about computers and are very dangerous. They can leave huge messes for real computer technicians/geeks to clean up. Many times so bad that it almost isn't worth the time fixing all the problems and your better off reformating. Nerdious falsius are hard to spot, because they still might have their A+ or MCSE or other cert or degree. How can the average population protect themselves from nerdius falsius? When you get your computer fixed, get it fixed from someone reputable in your area, even better is someone that someone else you've known has hired to fix their computer and has done a good job. How do I know about nerdious falsius? I have seen the damage they have done first hand. I went into a client's site for the first time, and they tell me this story, of how they had someone else come in and "fix" their computers. After he left, everything was in a worse state than it started out in. Everything was slow and lots of errors.
