The PC has become your gateway to the world. Now you can stay connected to friends, meet new people, shop in foreign countries, attend business meetings, and so much more all from the comfort of your living room or office. The problem is that Windows XP, Vista, and 7 fail to prevent the things you don’t want, like viruses from visiting you. Viruses can steal your personal data and destroy your PC, thus costing you hundreds to thousands of dollars. Anti-virus software is like a security guard with a list of mug shots that is regularly updated. While not perfect by any means, anti-virus is the best solution available to keep your Windows PC safe.
Mac and Linux users’ use of anti-virus software is mainly dependent on their environment. While there are some viruses out there for Mac and Linux systems, most of them are out-of-date and not a real threat. The real threat, once again is for Windows PCs. For example, if a Mac user downloads a file that contains a Windows virus and shares it with a Windows user, he or she could potentially infect that user’s PC. We call this the “Carrier Effect”. In this case, the Mac user should use anti-virus software. If not for himself/ herself then for the sake of other Windows users.
