How do I find the best antivirus for me?

The first thing to do is to understand what you need — all antiviruses come with different internet security tools to help you stay protected, so identifying what level of protection you want will help you figure out which product is right for you. Some antiviruses have a virtual private network (VPN), some have safe browsing extensions, and some have a password manager. Some only work on certain operating systems, while others cover all operating systems across multiple devices. It’s important to compare the best antiviruses on the market to find the perfect one with the functionality you need.

功能强大的防病毒软件需要做好两件事情：对恶意程序的高级防护和提供丰富的网络安全功能。Bitdefender和ZoneAlarm都采用了最新的应用签名和启发式扫描的技术，用于发现并对抗已知的和未知的恶意程序的攻击。尽管采取了不同的方式，但是它们都可以发现潜在的威胁。

Bitdefender，可以在多种操作系统中使用，会为您的系统提供多种类型的安全漏洞保护。硬件扫描功能可以检查任意USB驱动程序的状况，以确保在设备之间不会发生可疑的威胁传播。通过提供的虚拟键盘程序功能和密码管理程序，可以保护用户信息登录时的安全，避免键盘记录器的影响。摄像头保护功能Webcam Shield可以保护您的视频传输，避免黑客的劫持，文件安全管理程序Safe File Vault可以保护您的重要文件免于勒索软件的劫持。而SafePay浏览器是可用于网络支付时，保护用户的网银等信息的安全。

虽然ZoneAlarm仅提供了仅限Windows系统用户使用的软件版本，但也提供了丰富的安全附加功能，使其具有相当的价值。自动沙盒技术让所有的文件都在一个虚拟的环境中运行，以测试这些文件是否存在任何问题，一旦检测到任何异常便立即隔离。软件会在系统启动的阶段进行安全扫描检查，这在大多数的防病毒软件中也是少有的功能。高级的双向防火墙，可以检测出常见的绕过普通防火墙的方法，以增强安全性。此外，对于网络的安全保护服务可以增强无线网络的安全，通过对当前网络的风险分析更新防火墙的设置。最后，所有的用户都可以使用防网络钓鱼的Chrome浏览器扩展插件程序、防键盘记录器的协议服务、容量为5GB的在线备份空间、以及"Find My Laptop（查找我的笔记本电脑）"功能，以避免您的设备丢失或失窃。
