Free Virus Protection From Microsoft
If you’re looking for a free antivirus for home, you have several good options. But if you’re running a business, this is particularly good news! For years, free antivirus was only for home use, but Microsoft Security Essentials can be used on any genuine copy of Windows XP/Vista/7.
If your antivirus’ subscription is out of date, or if you’re not sure you’re protected, this is for you.
