如果您一直在默默地希望有一款强大、轻量、有效且免费的杀毒软件^{(free antivirus software)}，这个假期，那么您的愿望就实现了。 BitDefender发布了其防病毒工具的免费版本——BitDefender 免费防病毒版^{(BitDefender Free Antivirus edition)}。多年来，BitDefender的病毒检测和清除能力有了很大的提高，最近在不同的测试中也取得了很好的效果。

更新^(UPDATE)：Bitdefender Antivirus 免费版即将停用。您可能想看看其他一些适用于您的 Windows PC 的免费防病毒软件。

^{(BitDefender Free Antivirus)}适用于Windows 10的^{(Windows 10)}BitDefender 免费杀毒软件

Bitdefender Internet Security的开发人员 BitDefender 表示，其防病毒工具的免费版本使用世界上最有效的防病毒引擎之一，ICSA Labs 认证的扫描引擎可在其他BitDefender产品中免费找到。从而让您免费享受基本的病毒防护。它包括一个实时防护罩^{(Real-time Shield)}。实时屏蔽旨在保护对整个系统的访问。这意味着文件在被访问或复制时会被扫描。

该工具的大小略高于 200 MB。它会在您访问文件时检查文件，在您的 PC 空闲时运行偶尔的系统扫描，并自行清除所有感染。您还可以通过右键单击文件和文件夹并选择“使用 Bitdefender 扫描”来按需扫描文件和文件夹。该程序对您的整体系统性能的影响最小。

BitDefender 免费防病毒版^{(BitDefender Free Antivirus Edition)}没有笨重的桌面小工具，没有复杂的控制台或多选项卡设置对话框。您甚至不会看到任何警报，并且您还可以获得反网络钓鱼保护，从而防止您被恶意网站所困。

虽然，Bitdefender Antivirus Free看起来很有前途，并提供了良好的基本保护级别，仍然非常易于使用，但它无法与其他防病毒工具/产品（例如Norton Internet Security ）一起安装。它喜欢被用作主要的防病毒工具，而不是第二道防线——但我想，这是意料之中的。除此之外，没有任何问题！

简而言之，特点：^{(Features in a nutshell:)}

• 病毒扫描和删除^{(Virus Scanning and Removal)}：除了提供实时扫描外，它还提供按需和访问扫描、检测和删除所有恶意软件。
• 高级威胁检测^{(Advanced Threat Detection)}：它使用行为检测来密切监视您的活动应用程序。当它检测到任何可疑的东西时，它就会采取行动。
• 反网络钓鱼^{(Anti-Phishing)}：它检测并阻止网络钓鱼网站
• 反欺诈^(Anti-Fraud)：每当您访问可能试图欺骗您的网站时，它都会向您发出警告，例如赌场、货币贷款计划等。

请^(Please)注意，当您在Windows上安装该产品时，它会显示一个对话框，上面写着“您需要注册您的Bitdefender安装才能在到期后继续使用该产品”，并且还有“x”天可以登录。您必须在Bitdefender注册（创建一个帐户）才能在产品推广（免费）之后使用它。

如果您已经测试过BitDefender 免费杀毒版^{(BitDefender Free Antivirus Edition)}，请在下面的评论部分告诉我们您的评论。可以在这里^(here)(here)下载。

更新^(UPDATE)：它现在还包括一个隔离功能，可以防止受恶意软件感染的文件造成伤害，如果您计划访问的网页是危险的，则会向您发出警告等等。

Bitdefender Free Antivirus Edition for Windows 10

Іf you havе been wishing silently fоr a ѕtrong, lightweight and effective, yet free antivirus software, this holiday season, then your wish is being fulfilled.  BitDefender has released a free edition of its antivirus tool – BitDefender Free Antivirus edition. Over the years, BitDefender has improved greatly in its virus detection and removal capabilities and recently has been showing great results in different tests.

UPDATE: Bitdefender Antivirus Free Edition is to be retired soon. You might want to take a look at some other free antivirus software for your Windows PC.

BitDefender Free Antivirus for Windows 10

BitDefender, the developers of Bitdefender Internet Security say that the free edition of its antivirus tool uses one of the world’s most effective antivirus engines, ICSA Labs certified scanning engines found in other BitDefender products for free. Thereby allowing you to enjoy basic virus protection for no cost at all. It includes a Real-time Shield. The real-time shield is designed to protect access to the entire system. This means that files are scanned as they are accessed or copied.

The tool is a little over 200 MB in size. It checks files as you access them, runs occasional system scans when your PC is idle, and cleans up any infections all on its own. You can also scan files and folders on demand by right-clicking them and choosing ‘Scan with Bitdefender’. The program has the least impact on your overall system performance.

BitDefender Free Antivirus Edition features no bulky desktop gadgets, no complex console or multi-tabbed Settings dialog. You won’t even see any alerts and you get anti-phishing protection too, thus preventing you from getting trapped by malicious sites.

Although, Bitdefender Antivirus Free looks very promising and provides a good basic level of protection, remains exceptionally easy to use, it resists getting installed alongside another antivirus tool/product such as Norton Internet Security. It likes to be used as primary antivirus tool and not as a second line of defense – but then I suppose, that is to be expected. Apart from this, no issues!

Features in a nutshell:

• Virus Scanning and Removal: Apart from offering real-time scanning it also offers on-demand & on-access scanning, detection and removal of all malware.
• Advanced Threat Detection: It uses behavioral detection to closely monitor your active apps. When it detects anything suspicious, it takes action.
• Anti-Phishing: It detects and blocks Phishing websites
• Anti-Fraud: It warns you whenever you visit websites that may try to scam you, such as casinos, money loan schemes, etc.

Please note that when you install the product on Windows, it displays a dialog box which says “You need to register your Bitdefender installation to continue using this product after the expiration period” and there is a “x” days left to login. It is essential that you register with Bitdefender (create an account) to use it after that the product is as promoted ( free).

UPDATE: It now also includes a Quarantine function that prevents malware-infected files from doing harm, warns you if a web page you plan to visit is dangerous, and more.
