How do I find the best antivirus for me?

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.

Bitdefender是一家在防病毒市场领域内受到认可的品牌，但是获得认可并不意味着是最好的选择。相比较于Avast，它提供了基于行为的扫描以检测任何新型的威胁。都提供了防网络钓鱼和防勒索软件的功能，此外还有安全的密码管理程序和摄像头保护功能。

这两款产品的不同体现在价格和附加功能上。Bitdefender提供了丰富的附加功能，包括硬件扫描功能，可以对USB设备和外接驱动器设备进行安全检查，虚拟键盘程序可以防御键盘记录器，还有安全的浏览器‘SafePay’，可以阻止您在不安全的网站输入包括网银在内的敏感信息并保护这些信息的安全。智能助手程序AutoPilot工具软件，会在需要更新升级时及时向您通知提醒。需要注意的是，这些功能均可能消耗一定的系统资源，有可能造成系统速度的减慢。

Avast也许没有提供这么多的功能，但是也有沙盒功能，让应用程序和文件在虚拟的环境中启动并运行，将恶意程序可能带来的影响降到最低。‘Game Mode（游戏模式）’和‘Passive Mode（被动模式）’会暂停任何通知内容和对CPU消耗过高的程序，以避免中断和延时。Avast也是一款预算相对友好的选择；甚至提供了具有重要功能的免费版本的软件供用户使用。
