Sometimes taking care of your computer can be a real hassle. I like to think about it like a car. if you were a professional driver, driving your car 8 hours a day 5 days a week, how often do you think you need to change your oil, rotate your tires, do tuneups and so on?
Well, your computer is no different and Antivirus scans are one of the things we do to maintain your computer.
I personally recommend Vipre Antivirus
