免费防病毒解决方案的市场包括许多选择，但没有多少能真正提供他们所承诺的。卡巴斯基(Kaspersky)是这个市场上的新人，自去年以来，他们免费向任何想要使用它的人提供他们的防病毒引擎。(antivirus engine)它以Kaspersky Free Antivirus(Kaspersky Free Antivirus)的名义分发，您可以立即下载并开始使用，无需支付任何费用。我们很想知道它是否值得您花时间，所以我们决定测试一段时间。以下是我们发现的有关卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)的信息：
优点和缺点
这些是在Kaspersky Free Antivirus(Kaspersky Free Antivirus)中引起我们注意的积极因素：
- 它具有出色的防病毒引擎(antivirus engine)，可以有效地保护您免受恶意软件的侵害
- 它在保护您免受在线威胁（包括网络钓鱼网站）方面做得非常出色
- 它对计算机性能和启动时间的影响可以忽略不计(performance and boot time)
- 用户界面(user interface)干净，易于使用和理解
- 它捆绑了一个VPN 工具(VPN tool)，可以在连接到公共WiFi网络时保护您
卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)唯一的小缺点是您应该在安装后手动更新它。安装后，卡巴斯基(Kaspersky)似乎没有立即开始更新。
判决
Kaspersky Free Antivirus是我们测试过的最好的免费防病毒解决方案之一。它可以保护其用户免受离线和在线(offline and online)的各种恶意软件的侵害，并且易于使用。如果您想要一款比默认Windows Defender更好但成本相同的防病毒软件，这意味着它是免费的，我们相信卡巴斯基免费防病毒软件(Kaspersky Free Antivirus)是您可以做出的最佳选择之一。
下载安装体验(download and installation experience)
要在您的Windows PC上安装(Windows PC)Kaspersky Free Antivirus，您首先必须下载它(download it)。您下载的文件是一个名为kfa18.0.0.405abcden_es_fr_13382.exe的可执行文件，大小为 2.32MB。在下载防病毒软件之前，您必须向卡巴斯基(Kaspersky)提供有关个人信息的唯一信息是电子邮件地址。(email address)安装向导从(setup wizard)Kaspersky的服务器下载了 125.3 MB 的数据，这并不多。
在安装过程中，您可以选择是否“想要加入卡巴斯基安全网络 (KSN) 以为 [您的] 计算机提供最佳保护”。("want to participate in Kaspersky Security Network (KSN) to provide optimal protection for [your] computer.")我们建议您启用此选项，因为它有助于卡巴斯基(Kaspersky react)更快地应对新的网络威胁。
安装完成后，卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)会立即开始保护您。它还要求您创建或登录“我的卡巴斯基”(My Kaspersky)在线帐户。但是，这不是强制性的，因此您可以跳过此步骤。
即使我们等了大约 15 分钟并且用户界面(user interface)显示需要更新，卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)也没有启动自动更新。我们尝试重新启动计算机，但也没有成功，所以我们别无选择，只能加载套件的用户界面并手动运行更新。如果您想要最新的保护，我们建议您这样做。
我们与卡巴斯基免费杀毒软件的第一次互动大多是积极的：除了真实的电子邮件地址之外，您无需提供任何个人信息即可下载和使用杀毒软件，这很好。还值得注意的是，在您的计算机上安装防病毒软件很简单。但是，您需要记住在安装后立即手动更新它。(Our first interactions with Kaspersky Free Antivirus are mostly positive: it is good that you do not have to provide any personal information to download and use the antivirus, other than a real email address. It is also worth noting that it is straightforward to install the antivirus on your computer. However, you need to remember to manually update it as soon as you install it.)
与Windows 和 Web 浏览器(Windows and web browsers)集成
在安装过程中，卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)会禁用Windows Defender，这是一件好事，因为它消除了冲突或性能问题的可能性。此外，您应该知道卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)会扫描您计算机上的所有互联网流量(internet traffic)，因此无论您喜欢使用哪种网络浏览器(web browser)，您都可以获得相同的保护。(protection regardless)
Kaspersky Free Antivirus保护其所有进程免受意外终止，这是一个积极的方面。讨厌的病毒无法阻止您的防病毒软件并在您的计算机上为所欲为。
关于系统资源需求，杀毒软件(antivirus software)需要大约 60 MB 的RAM来运行其进程，这并不多。此外，卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)对我们测试计算机的(test computer)启动时间(boot time)影响很小。我们在安装杀毒软件之前和之后使用BootRacer进行了测量，我们发现它只增加了 1 秒，这意味着增加了 2% 的时间(percent time increase)。
为了检查互联网或本地网络速度是否受到卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)的影响，我们还使用Speedtest.net和LAN Speed Test进行了一些测试。安装此防病毒软件之前和之后的速度相同，这意味着它对 Internet 或本地网络数据传输没有不利影响。
Kaspersky Free Antivirus 与 Windows 10 完美集成。它对我们测试计算机的启动时间影响很小，并且对网络传输和互联网速度没有不利影响。(Kaspersky Free Antivirus is well integrated with Windows 10. It had a minimal influence on the boot time of our test computer, and it had no adverse effect on network transfers and internet speeds.)
易于使用和配置
Kaspersky Free Antivirus提供的用户界面与其大哥卡巴斯基全方位安全(Kaspersky Total Security)软件使用的相同，但不可用的工具显示为灰色。用户界面(user interface)在其顶部区域显示状态和建议部分(status and recommendations section)，并在一切正常时使用大的绿色瓷砖。当出现问题时，瓷砖会变成红色，因此您不会错过需要您注意的问题这一事实。在中央控制台上，您可以快速访问扫描(Scan)和数据库更新(Database Update)工具。
如果您正在寻找更多，您可以单击或点击用户界面(user interface)底部的更多工具(More Tools)按钮，您可以访问云保护、屏幕键盘(Cloud Protection, On-Screen Keyboard)、隔离(Quarantine)和报告(Reports)：
-
Cloud Protection显示全球恶意软件统计数据，

在用户界面(user interface)的左下角，有一个小齿轮按钮(cogwheel button)，可让您访问设置(Settings)。它们分为五个不同的部分：常规、保护、性能、扫描(General, Protection, Performance, Scan, )和附加(Additional)。
一些最重要的设置可以在Protection中找到，您可以在其中找到所有保护模块。只需单击或点击它们的开关，它们中的每一个都可以快速打开或关闭。如果您想访问他们的详细设置，您可以单击或点击他们的名字。
关于帮助和支持(help and support)，您应该知道，杀毒软件(antivirus software)中的大多数操作和设置在上下文中都有很好的解释。如果您需要更复杂的帮助或支持(help or support)，您可以上网浏览文档或搜索论坛。但是，您还必须注意，卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)的用户无法通过电话或网站上的查询表获得技术支持。
Kaspersky Free Antivirus还会创建报告，在其中显示您计算机上发生的情况，它们既易于理解又包含详细信息。
至于您从中获得的警报和通知，卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)并不太冗长。但是，我们注意到，如果您不注册“我的卡巴斯基”(My Kaspersky )帐户，确实会让您感到不安。
Kaspersky Free Antivirus 的用户界面看起来不错且易于使用。它结构良好，很容易找到和配置可用的设置和选项。(Kaspersky Free Antivirus has a user interface that looks good and is also easy to use. It is well structured, and it is easy to find and configure the settings and options available.)
防病毒和反间谍软件保护(Antivirus and antispyware protection)
我们通过检查Kaspersky Free Antivirus在您上网时如何处理在线威胁来开始我们的防病毒测试。它通过扫描所有互联网流量(internet traffic)并过滤掉所有恶意网页内容(web content)来做到这一点，无论您喜欢哪种网络浏览器，它都能为您提供保护。
为了了解它的表现如何，我们使用了最流行的网络浏览器（Microsoft Edge、Google Chrome、Mozilla Firefox和Opera）并访问了几个危险的网站。正如我们所料，每次我们尝试时，卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)都会阻止我们在所有网络浏览器中访问受感染的网页。
接下来，我们想看看当我们将受感染的可移动USB 记忆(USB memory)棒连接到我们的计算机时，防病毒软件会做什么。(antivirus software)它如我们所愿：它检测到USB 记忆(USB memory)棒并询问我们是否要扫描它。我们答应了，卡巴斯基免费杀毒软件立即(Kaspersky Free Antivirus)扫描并清理了USB 记忆(USB memory)棒。
然后我们拿了测试笔记本电脑(test laptop)，在上面安装了Windows 10，我们在里面装满了各种恶意软件，包括一些勒索软件样本。重新启动后，Windows 10几乎无法使用，因为它受到了感染。然后我们上网下载并安装Kaspersky Free Antivirus。我们设法做到了，一旦防病毒软件(antivirus software)启动并运行，它会识别出一些受感染的进程和文件，并开始对它们进行消毒并将其从系统中删除。
经过全面系统扫描后，防病毒软件设法清除了我们计算机上的所有恶意软件。这是一个极好的结果。
杀毒软件的扫描速度也很重要：在我们的 Windows 10测试笔记本电脑(test laptop)上，卡巴斯基免费杀毒软件(Kaspersky Free Antivirus )平均需要 4 分钟来扫描 130 GB 的系统(GB system)分区和 35 GB 的文件。这是一个快速的防病毒扫描时间。
我们还查看了其他独立安全组织对卡巴斯基(Kaspersky)的评价：
-
AV-Test在所有测试（(AV-Test)保护、性能、(Protection, Performance, Usability)可用性）中以 6 分（满分 6 分）对卡巴斯基进行评级。

Kaspersky Free Antivirus 拥有世界上最好的防病毒引擎之一，我们的测试证实了这一点。(Kaspersky Free Antivirus has one of the best antivirus engines in the world, and our tests confirm it.)
额外功能
卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)只捆绑了一个东西：一个称为安全连接(Secure Connection.)的 VPN 解决方案。这是Kaspersky与Hotspot Shield联合提供的VPN 服务(VPN service)。如果您想在公共不可信的无线网络（例如咖啡店或机场的无线网络）上保持安全，那么使用VPN 服务是一个绝妙的主意。(VPN service)它是卡巴斯基免费杀毒软件(Kaspersky Free Antivirus, )的绝佳补充，但您应该知道，它每天的互联网(MB internet)流量上限为 200 MB。
要获得更多流量，您必须购买VPN 解决方案(VPN solution)的订阅。如果您想了解有关此VPN 服务(VPN service)的更多详细信息，我们已在此处对其进行了审查：所有人的安全性 - 审查卡巴斯基安全连接 VPN(Kaspersky Secure Connection VPN)。
(Default)您可能想要调整的默认设置
Kaspersky Free Antivirus中的大多数设置默认配置良好，但也有一些您可能更愿意更改：
-
Kaspersky Free Antivirus默认设置为在计算机空闲时扫描您的计算机。这是一个很好的方法。但是，没有定期安排防病毒扫描。如果您想进一步提高安全性，您可能希望每月至少安排一次全面扫描。您可以在"Settings -> Scan -> Scan schedule."
-
Kaspersky Free Antivirus不仅可以设置为检测病毒、蠕虫、木马和广告软件，还可以检测黑客可以用来“损坏您的计算机或个人数据”的其他类型的软件。("damage your computer or personal data.")这是一个默认禁用的设置 - 您可以在"Settings -> Additional -> Threats and Exclusions settings -> Detect other software that can be used by criminals to damage your computer or personal data."
- 获得有关计算机上发生的安全相关事件的通知是一件好事，但如果您不想在收到声音时听到声音，或者不想接收来自卡巴斯基(Kaspersky)的广告和促销通知。"Settings -> Additional -> Notifications."中更改这些行为。
- 如果由于您在计算机上工作而在处理器和磁盘负载过重时(processor and disks)卡巴斯基免费杀毒软件(Kaspersky Free Antivirus)难以运行扫描，您可以推迟卡巴斯基(Kasperky)的扫描，直到您的计算机资源被释放。此设置位于"Settings -> Performance -> Postpone computer scan tasks when the CPU and disk systems are at high load."
我们发现 Kaspersky Free Antivirus 默认配置良好。但是，您可以更改一些设置以使卡巴斯基按照您喜欢的方式运行。(We found Kaspersky Free Antivirus to be well configured by default. However, there are some settings that you can change to make Kaspersky run the way you like it.)

Security for everyone - Review Kaspersky Free Antivirus
The market for free antivirus solutions includeѕ many choices, but not many of them genuinely offer what they рromise. Kaspersky is a newcomer on this market, and sincе last year, they have offered theіr antivirus enginе for free, to anyone who wants to use it. It is distributed under the name of Kaspersky Free Antivirus, and you can download and start using right away, without having to pay anything. We were curious to see if it is worth your time, so we decided to test it for a while. Here is what we found about Kaspersky Free Antivirus:
Pros and cons
These are the positives that sparked our attention in Kaspersky Free Antivirus:
- It has an excellent antivirus engine that can protect you efficiently against malware
- It does an outstanding job at protecting you from online threats, including phishing websites
- It has a negligible effect on your computer's performance and boot time
- The user interface is clean, easy to use and understand
- It bundles a VPN tool that can protect you when connected to public WiFi networks
The only minor negative about Kaspersky Free Antivirus is the fact that you should manually update it after installing it. Kaspersky does not seem to start the update right away, after its installation.
Verdict
Kaspersky Free Antivirus is one of the best free antivirus solutions that we have ever tested. It protects its users against all kinds of malware, both offline and online, and it is easy to use. If you want an antivirus that is better than the default Windows Defender but which costs the same, meaning that it is free, we believe that Kaspersky Free Antivirus is one of the best choices that you could make.
The download and installation experience
To get Kaspersky Free Antivirus on your Windows PC, you first have to download it. The file you download is an executable file called kfa18.0.0.405abcden_es_fr_13382.exe with a size of 2.32MB. The only thing that you must offer Kaspersky regarding personal information is an email address, before downloading the antivirus. The setup wizard downloads 125.3 MB of data from Kaspersky's servers, which is not a lot.
During the installation, you can choose if you "want to participate in Kaspersky Security Network (KSN) to provide optimal protection for [your] computer." We recommend that you enable this option as it helps Kaspersky react faster against new cyber threats.
When the installation is finished, Kaspersky Free Antivirus starts protecting you immediately. It also asks you to create or sign in to your My Kaspersky online account. However, that is not mandatory, so you can just skip this step.
Even after we waited for about 15 minutes and the user interface said that an update was required, Kaspersky Free Antivirus did not start an automatic update. We tried to reboot the computer but that did not work either, so we had no choice but to load the suite's user interface and manually run the update. We recommend that you do the same if you want the most recent protection.
Our first interactions with Kaspersky Free Antivirus are mostly positive: it is good that you do not have to provide any personal information to download and use the antivirus, other than a real email address. It is also worth noting that it is straightforward to install the antivirus on your computer. However, you need to remember to manually update it as soon as you install it.
Integration with Windows and web browsers
During the installation, Kaspersky Free Antivirus disables Windows Defender, and that is a good thing because it eliminates the chance of conflicts or performance issues. Also, you should know that Kaspersky Free Antivirus scans all the internet traffic that goes on your computer, so you get the same protection regardless of the web browser you prefer to use.
Kaspersky Free Antivirus protects all its processes from unwanted termination, and that is a positive. Nasty viruses cannot stop your antivirus and do whatever they want on your computer.
Regarding system resources needs, the antivirus software takes about 60 MB of RAM to run its processes, which is not much. Also, Kaspersky Free Antivirus had a minimal effect on the boot time of our test computer. We used BootRacer to measure this before and after we installed the antivirus, and we found that it only added 1 second, and that means a 2 percent time increase.
To check whether the internet or local network speeds are affected by Kaspersky Free Antivirus, we also ran a few tests with Speedtest.net and with LAN Speed Test. The speeds were the same before and after installing this antivirus, which means that it has no adverse effect on the internet or local network data transfers.
Kaspersky Free Antivirus is well integrated with Windows 10. It had a minimal influence on the boot time of our test computer, and it had no adverse effect on network transfers and internet speeds.
Ease of use & configuration
The user interface offered by Kaspersky Free Antivirus is the same as the one used by its big brother Kaspersky Total Security, but the tools that are not available are greyed out. The user interface shows the status and recommendations section in its top area and uses large green tiles when everything is OK. When something is wrong, the tiles turn red, so you cannot miss the fact that there are problems that require your attention. On the central console, you get quick access to the Scan and Database Update tools.
If you are looking for more, you can click or tap the More Tools button from the bottom of the user interface, and you get access to Cloud Protection, On-Screen Keyboard, Quarantine, and Reports:
-
Cloud Protection shows worldwide malware statistics,
-
On-Screen Keyboard is a virtual keyboard that you should use when you want to make sure that the data you enter is not logged by third-party apps or by malware,
-
Quarantine gives you access to the infected files that have been detected on your Windows computer, and
-
Reports provide you with access to the antivirus logs.
On the user interface, on the bottom left corner, there is a small cogwheel button that lets you access the Settings. They are divided into five different sections: General, Protection, Performance, Scan, and Additional.
Some of the most important settings are found in Protection, where you can find all the protection modules. Each of them can be quickly turned on or off with just a click or tap on their switches. If you want to access their detailed settings, you can click or tap on their names.
Regarding help and support, you should know that most of the actions and settings in the antivirus software are well explained in context. If you need more complex help or support, you can go online and browse the documentation, or scour the forums. However, you must also be aware of the fact that users of Kaspersky Free Antivirus do not have access to technical support via phone or the query form on the website.
Kaspersky Free Antivirus also creates reports in which it shows you what happened on your computer, and they are both easy to understand and full of detailed information.
As for the alerts and notifications you get from it, Kaspersky Free Antivirus is not too verbose. However, we have noticed that it does get on your nerves if you do not register an My Kaspersky account.
Kaspersky Free Antivirus has a user interface that looks good and is also easy to use. It is well structured, and it is easy to find and configure the settings and options available.
Antivirus and antispyware protection
We started our antivirus tests by checking how Kaspersky Free Antivirus handles online threats when you surf the web. It does that by scanning all the internet traffic and by filtering out all the malicious web content, and it protects you no matter what web browser you prefer.
To see how well it does that, we used the most popular web browsers (Microsoft Edge, Google Chrome, Mozilla Firefox, and Opera) and visited several dangerous websites. As we expected, Kaspersky Free Antivirus blocked our access to the infected web pages each time we tried, in all the web browsers.
Next, we wanted to see what the antivirus software does when we connect an infected removable USB memory stick to our computer. It did just as we wished: it detected the USB memory stick and asked us whether we wanted to scan it. We said yes, and Kaspersky Free Antivirus scanned and cleaned the USB memory stick in no time.
Then we took the test laptop, we installed Windows 10 on it, and we filled it with all sorts of malware, including some ransomware samples. After a reboot, Windows 10 was almost unusable because of the infection on it. We then went online to download and install Kaspersky Free Antivirus. We managed to do it, and once the antivirus software was up and running, it identified some infected processes and files and started to disinfect and remove them from the system.
After a full system scan, the antivirus managed to clean all the malware on our computer. This is an excellent result.
The antivirus scanning speed is also important: on our Windows 10 test laptop, Kaspersky Free Antivirus needed an average of 4 minutes to scan the 130 GB system partition with 35 GB of files on it. This is a fast antivirus scan time.
We also looked at what other independent security organizations had to say about Kaspersky:
-
AV-Test rated Kaspersky with their maximum score of 6 points out of 6, in all their tests (Protection, Performance, Usability).
-
AV-Comparatives awarded Kaspersky with their top Advanced+ badge in all their security tests this year (Malware Protection, Performance, Real World Protection).
-
Virus Bulletin gave Kaspersky their VB100 mark.
Kaspersky Free Antivirus has one of the best antivirus engines in the world, and our tests confirm it.
Extra features
There is only one thing bundled with Kaspersky Free Antivirus: a VPN solution called Secure Connection. It is a VPN service offered by Kaspersky in association with Hotspot Shield. Using a VPN service is an excellent idea if you want to stay safe on public untrustworthy wireless networks such as those in coffee shops or airports. It is an excellent addition to Kaspersky Free Antivirus, but you should know that it is capped at a maximum of 200 MB internet traffic per day.
For more traffic, you have to buy a subscription to the VPN solution. If you want more details about this VPN service, we have reviewed it here: Security for everyone - Reviewing Kaspersky Secure Connection VPN.
Default settings you might want to adjust
Most of the settings in Kaspersky Free Antivirus are configured well by default, but there also a few which you might prefer to change:
-
Kaspersky Free Antivirus is set by default to scan your computer while it is idle. This is a great approach. However, there are no antivirus scans scheduled at regular time intervals. If you want to increase your security even further, you might want to schedule at least a full scan once a month. You can do this in "Settings -> Scan -> Scan schedule."
-
Kaspersky Free Antivirus can be set to detect not just viruses, worms, trojans, and adware but also other types of software that can be used by hackers to "damage your computer or personal data."This is a setting which is disabled by default - you can find it in "Settings -> Additional -> Threats and Exclusions settings -> Detect other software that can be used by criminals to damage your computer or personal data."
- It is a good thing to get notifications about security-related events that take place on your computer, but if you do not want to hear sounds when you get them, or if you do not want to receive advertisements and promotional notifications from Kaspersky. You can change these behaviors in "Settings -> Additional -> Notifications."
- If Kaspersky Free Antivirus is having a hard time running scans when your processor and disks are under heavy load because you are working on your computer, you can postpone Kasperky's scans until your computer resources are being freed up. This setting is found in "Settings -> Performance -> Postpone computer scan tasks when the CPU and disk systems are at high load."
We found Kaspersky Free Antivirus to be well configured by default. However, there are some settings that you can change to make Kaspersky run the way you like it.
