'''Microsoft Security Essentials'''（簡稱'''{{lang|en|MSE}}'''，直译微软安全要点）是由[[微軟]]开发及发行的免费[[杀毒软件]]，用于防止[[计算机病毒]]、[[间谍软件]]、[[Rootkit]]和[[特洛伊木马 (电脑)|木马]]等[[恶意软件]]，取代了[[Windows Live OneCare]]和[[Windows 7]]及更早期版本中内置的[[Windows Defender]]。4.5前的版本可在[[Windows XP]]、[[Windows Vista]]、[[Windows 7]]运行，但[[Windows 8]]起系统已内置Windows Defender，无法运行MSE；4.5及以后的版本不能在Windows XP运行。[[最终用户许可协议]]允许家庭用户和小企业免费安装和使用本产品。

它基于与其他微软防病毒产品相同的扫描引擎和病毒定义，提供实时保护，不断检测计算机上的活动，在创建或下载新文件时扫描新文件，并禁用检测到的威胁。它缺少OneCare个人防火墙和Forefront Endpoint Protection集中管理功能。

微软于2008年11月18日宣布推出自己的反病毒软件，反病毒软件行业对此褒贬不一。[[赛门铁克]]、[[迈克菲]]和[[卡巴斯基实验室]]三家相互竞争的独立软件供应商将其视为不值得竞争的对手，但{{link-en|AVG科技|AVG Technologies}}和[[Avast Software]]赞赏它有可能增加消费者对杀毒软件的选择。AVG、迈克菲、{{link-en|Sophos}}和趋势科技声称，将该产品集成到Microsoft Windows将违反竞争法。

该产品以其简洁的用户界面、较低的资源使用率和免费软件许可证而获得普遍的积极评价，并于2009年10月获得[[AV-TEST]]认证。但认证在2012年10月撤销，表明产品的保护和修复功能在不断下降。2013年6月，MSE得到最低的保护得分，即0分。据[[OPSWAT]]2012年3月的报告，MSE是在北美地区最流行的和世界第二流行的杀毒软件，因此一些[[恶意软件]]试图模仿它的外观。

== 功能 ==
MSE默认自动检查更新，每天由[[Microsoft Update]]自动下载更新病毒定义三次，{{r|Mills}}用户也可以从Microsoft Security Portal网站手动下载更新。{{r|ms-web-kb-updates}}2011年9月30日，病毒定义更新出错，软件将[[Google Chrome]]标记为恶意软件，这失误在3小时内得到修正。{{r|GoogleChrome1|GoogleChrome2}}MSE的早期版本可以在Windows XP、Windows Vista、Windows 7运行，{{r|sysreqmain}}而4.5及更高版本不能在Windows XP运行，{{r|Popa}}而且微软于2015年7月14日停止为Windows XP自动更新定义，但用户仍可手动更新定义。{{r|ms-web-kb-updates|Serdar}}

MSE基于[[OneCare]]來开发，使用与其他微软安全产品相同的病毒定义，并用微软恶意程序保护引擎（{{lang|en|Microsoft Malware Protection Engine}}，MSMPENG）來扫描，{{r|Tesar|MSMPENG}}但没有OneCare的[[个人防火墙]]和[[Microsoft Forefront]]的集中管理功能。{{r|SuperSite}}

MSE提供[[实时保护]]，能够实时监视电脑上的活动，并扫描创建和下载的新文件。{{r|Krebs}}它隔离检测到的威胁，并提示用户选择如何处理威胁。如果用户在10分钟内没有回应，MSE将根据病毒定义执行指定的默认动作，必要时会在移除恶意软件时创建[[系统还原]]点。{{r|Krebs}}作为实时保护的一部分，MSE默认会向基于网络的{{link-en|微软主动保护服务|Microsoft Active Protection Service}}报告受监控程序的所有可疑行为。{{r|Ilascu 25-Apr-2012}}如果报告与新发现的恶意软件威胁和尚未正式发布的定义相匹配，MSE将会下载新定义以移除威胁。{{r|Ditto-Ehlert}}

{{System requirements|collapse=yes|platform1=[[Microsoft Windows]]|os1=[[Windows 7]]、[[Windows Vista|Vista]]、[[Windows XP|XP]]|cpu1=1 GHz以上（Windows XP需要500 MHz以上）|memory1=1GB以上（Windows XP需要256MB以上）|hdspace1=200MB以上|network1=为了更新定义，计算机必须连接到互联网|display1=800×600像素以上}}
MSE的硬件要求取决于[[操作系统]]。Windows XP要[[时钟频率]]为500[[Hertz|MHz]]的[[中央处理器|处理器]]和256MB[[随机存取存储器|内存]]。Windows Vista或Windows 7需要时钟频率为1GHz处理器和1GB内存。它还需800×600[[像素]]的[[显示器]]，200MB可用[[硬盘]]空间和互联网连接。{{r|sysreqmain}}MSE有32位和64位版。{{r|mse-dc-download}}

MSE针对低配置设备做了优化，如只有1GB内存和[[Celeron]]核心的[[UMPC]]。MSE已包括Windows Defender的功能，如果系统有运行[[Windows Defender]]，MSE会把Windows Defender关闭。{{r|winsupersite-01}}

== 发展 ==
微软在2006年5月開始提供一体化的[[Windows Live OneCare]]，其在Windows防惡意軟件市场上只有2%的[[市場佔有率|市場占有率]]。事實上，MSE出現前，市場上已經有[[AVG Anti-Virus|AVG]]、[[Avast!|Avast]]、[[Avira AntiVir]]等不少免費的防惡意軟件，它們已佔有不少的市場。{{r|BBC}}OneCare在2009年6月终止服務。{{r|Microsoft 29-May-2012}}

2008年11月18日，微软宣布计划发布免费的消费者安全产品，[[微软产品代号列表|代号]]为Morro（意为“小丘”）。{{r|Microsoft 29-May-2012}}这标志微软改变了在[[消费者]]杀毒软件市场的策略：Morro将成为占用系统资源较小的免费杀毒软件，而不是带有许多附加工具（如[[备份]]和[[个人防火墙]]）并需要[[订阅]]的安全产品。{{r|BBC}}微软在线服务和Windows部门的产品高级主管艾米·巴兹杜卡斯（{{lang|en|Amy Barzdukas}}）称，Morro将不会与其他商业杀毒软件直接竞争，而是将没有或不希望购买杀毒软件的五六成PC用户作为目标。{{r|CRN, won't compete}}2009年6月17日透露Morro的官方名为“Microsoft Security Essentials”。{{r|Protalinski 17-Jun-2009}}

2009年6月23日，微软向[[美国]]、[[以色列]]、[[中国]]和[[巴西]]的用户发放了75000份[[测试版本|測試版]]，一天后关闭下载，显示“目前我们不接受额外参与者”。微软计划在2009年底发布面向20座市场和10种语言的产品，{{r|Foley 29-May-2012}}[[生产商发放|最终版]]于2009年9月29日发布。{{r|Mediata 28-Jun-2009}}

=== 2.0版 ===
在首次发布近一年后，微软悄然发布了MSE的第版本。新版于2010年7月19日进入[[軟件版本週期|技术预览]]阶段，{{r|beta-2-official|beta-2-cnet}}正式版于2010年12月16日发布。它包含了适用于Windows Vista和Windows 7的[[网络入侵检测系统]]——“网络监测系统”（{{langx|en|Network Inspection System}}，NIS），激活该系统需要单独一组定义更新。{{r|ms-web-kb-updates}}新版还有用[[启发法#计算机科学|启发法]]检测恶意程序的引擎，并与[[Internet Explorer]]整合，以防止[[网络攻击]]。{{r|Whitney 17-Dec-2010|Gordon}}

=== 4.0版 ===
2.0版发布十六个月后，微软跳过3.0版，发布4.0版。公开测试于2011年11月18日开始，当时微软并没有向受邀的潜在参与者宣布版本号。{{r|Foley 19-Nov-2011|Orin}}首份测试版于2011年11月29日发布，{{r|Bink 29-Nov-2011|TomsHardware}}最终版则于2012年4月24日发布。{{r|Ilascu 25-Apr-2012}}微软随后启动了预发布计划，为参与者提供最新的测试版并接受反馈。{{r|program7657}}

=== 4.5版 ===
2014年2月21日，4.5版进入测试阶段。{{r|softpedia-01}}同日，微软宣布自此版本后，MSE将不再支持Windows XP。{{r|Popa}}旧版仍可接收病毒定义更新，到2015年7月14日后，可以继续使用微软的网站手动更新定义。{{r|ms-web-kb-updates|Serdar}}2020年1月14日起，MSE停止服务，微軟不再提供下载。{{r|Support}}

=== 終止支援 ===
{{see also|Windows Defender}}
MSE已正式结束支援Windows Vista{{r|microsoft-02}}和Windows XP{{r|microsoft-03}}。这些系统仍能运行较旧版的MSE，但最新的定义已不再兼容。虽然于2020年1月14日结束支持Windows 7{{r|microsoft-04}}，但微软将在2023年前继续为用户提供病毒定义更新。{{r|Support}}

Windows 8及以上版本的系统已内置安全组件Windows Defender，不能运行MSE。2011年9月13日的[[阿納海姆 (加利福尼亞州)|安纳海姆]]的BUILD大会上，微软发布Windows 8开发者预览版，内置的安全组件能够防止受感染的USB[[闪存盘]]在操作系统启动时破坏系统。{{r|Whitney 13-Sep-2011|Kingsley-Hughes}}9月15日，微软在Windows 8开发者博客中确认，Windows 8中的Windows Defender将会有防病毒的功能。在包含的视频中，微软的杰森·加姆斯（{{Lang|en|Jason Garms}}）展示了将Windows Defender在[[Windows資訊安全中心|Windows 安全中心]]中注册为杀毒软件和反间谍工具的方法，以及Windows Defender拦截强制运行的恶意软件的过程。{{r|Sinofsky}}2012年3月3日，[[Softpedia]]审查了Windows 8开发者预览版，并注意到Windows Defender与MSE4.0 Beta在外观上的相似之处。Softpedia称，从Windows 7升级到Windows 8时，安装程序要求卸载MSE。{{r|Arghire}}

== 授权协议 ==
[[File:Microsoft_Security_Essentials_Genuine_Notification.PNG|alt=Screen dump|thumb|300x300px|MSE的弹出式通知表明，识别出Windows许可证问题，MSE将停止工作，直到问题解决]]

家庭用户可在个人电脑不限次数免费下载、安装并使用MSE，唯需每台电脑都有Microsoft Windows的合法许可副本。{{r|MSE-EULA}}从2010年10月开始，小型企业也可在至多10部设备安装该产品，{{r|Protalinski 17-Oct-2010}}但不可在政府机构或学术机构的设备使用，同时禁止[[反向工程|逆工程]]、[[反编译|逆编译]]或逆汇编该产品，或是绕过其设计限制。{{r|MSE-EULA}}

MSE无需在安装時注册或提交個人資料，{{r|Bott}}但在安装時及安装完成后，[[Windows正版增值计划]]会验证操作系统[[软件许可证|许可证]]是否有效，如果许可证无效，MSE将通知用户，并在一段时间后停止运行。{{r|MSE-EULA}}

== 评价 ==

=== 行业反响 ===
MSE的发布及公开亮相引起了杀毒软件行业的不同反响。MSE的三間主要竞争厂商[[赛门铁克]]、[[迈克菲]]和[[卡巴斯基实验室]]称其不如自家产品。{{r|Gregg}}赛门铁克诺顿产品的工程副总裁延森·梅格思（{{lang|en|Jens Meggers}}）认为其“非常平庸，没有突出特点”。{{r|Messmer}}赛门铁克的汤姆·鲍利奇（{{lang|en|Tom Powledge}}）敦促他的顾客注意他们选择的保护，并称OneCare提供了“不合格的保护”和“劣质的用户体验”。{{r|Schofield 27-Nov-2008}}迈克菲的全球公共关系总监尤里斯·埃弗斯（{{lang|en|Joris Evers}}）说：“OneCare的市场份额不到2%，我们理解微软决定将注意力转移到他们的核心业务上。”{{r|Reception}}卡巴斯基的贾斯汀·普里斯特利（{{lang|en|Justin Priestley}}）认为微软“在消费者市场的份额持续低迷，我们不认为OneCare的退出会改变市场格局。”{{r|Reception}}

[[Avast Software]]对MSE有矛盾的观点。Avast Software的CEO{{link-en|文斯·斯特克勒|Vince Steckler}}表示：“MSE虽然不是万金油，但也不是一些人所谓的{{sic|One Care}}失败续作。”{{r|Steckler}}{{link-en|AVG科技|AVG Technologies}}的一位代表说：“我们认为这在杀毒软件行业中是积极的一步。AVG在过去八年里相信免费杀毒软件是正确的。”{{r|Reception}}但是，AVG对分发产品提出了问题：“微软要做的不只是提供这产品，还应该做更多事。”{{r|Reception}}并补充说，把产品整合到[[Microsoft Windows]]将会违反[[競爭法]]。{{r|Schofield 11-Jun-2009}}迈克菲、{{link-en|Sophos}}和后来的[[趋势科技]]申明，如果微软将其与Windows捆绑，反垄断诉讼会随之而来。{{r|Fried|Bright}}

MSE的发布影响了其他杀毒软件厂商的[[股票]]。2008年11月19日，在微软宣布Morro代号后，赛门铁克和迈克菲的[[股价]]分别下跌9.44%和6.62%。{{r|CRN, won't compete}}2009年6月10日，在宣布即将推出测试版后，微软股价上涨2.1%，赛门铁克和迈克菲的股价分别下跌0.5%和1.3%。{{link-en|FBR Capital Markets|FBR Capital Markets}}的[[分析师]]丹尼尔·艾夫斯（{{lang|en|Daniel Ives}}）认为，MSE将会成为“长期竞争威胁”，但短期影响不大。{{r|Reuters}}

=== 评价和奖项 ===
公开测试版在低资源占用率、简洁的[[用户界面]]和价格方面获得了一些评价。{{r|Krebs|PCMag|PCWorld|SatishSays}}[[华盛顿邮报]]的{{link-en|布莱恩·克雷布斯|Brian Krebs}}报告在[[Windows 7]]上执行快速扫描需要10分钟，完整扫描需要45分钟。{{r|Krebs}}[[Ars Technica]]对它有条理的界面、低资源占用率和价格免费给予了积极评价。{{r|Protalinski 29-Sep-2009}}

[[PCWorld]]的尼克（{{lang|en|Nick Mediati}}）注意到MSE的明确简洁和选项卡式的[[用户界面]]。然而，他发现一些神秘和令人困惑的设置：默认采取的“推荐操作”，它的唯一解释只能在帮助文件找到。最初他还因更新感到疑惑，因为用户界面没有提到MSE将会自动更新，而不必手动通过“更新”选项卡更新；{{r|PCWorld}}最终版增加了这功能的解释。{{r|Ilascu 1-Oct-2009}}

[[PC Magazine]]的尼尔（{{lang|en|Neil Rubenking}}）成功在12台受恶意软件感染的系统安装测试版，并评价了它的小尺寸安装包（约7MB，取决于操作系统）和快速的安装过程。但首次病毒定义更新需要5至15分钟，且完整安装会占用110MB左右的磁盘空间。尼尔还注意到在安装过程中会切换[[Windows Update]]到全自动模式，但之后可以通过[[Windows控制面板]]手动切换回来。一些完整扫描在受感染的系统上可能需1小时以上；在未感染的系统上约35分钟。{{r|PCMag}}尼尔于2009年6月使用MSE测试版的一次扫描测试中，MSE发现了89%的恶意软件：30%的商业键盘记录程序和67%的Rootkit，但只发现了一半的[[伪安全软件]]样本。产品的实时保护發现了83%的恶意软件并拦截了大多数：发现了40%的商业键盘记录程序和78%的Rootkit。{{r|PCMag}}

[[File:AV-TEST.org_-_MSE_results_on_chart.png|thumb|300x300px|[[AV-TEST]]从2010年6月到2013年6月测试MSE的结果：'''{{Color|#5b9bd5|保护}}'''、'''{{Color|#ed7d31|修复}}'''和'''{{Color|#a5a5a5|易用}}''']]
2010年1月7日，MSE赢得了{{link-en|PC Advisor|PC Advisor}}的“最佳免费软件”奖项。{{r|PCAdvisor}}同年12月，它因其对新或未知恶意软件的55%的主动防御检测率、低误报率（测试时发生了6次）和总体性能，分别赢得了[[AV-Comparatives]]的铜奖（{{lang|en|Bronze}}）、银奖（{{lang|en|Silver}}）和铜奖。{{r|SummaryReport}}

2009年10月，[[AV-TEST]]试用了一系列最终版的杀毒软件，MSE从545,034个[[计算机病毒]]、[[電腦蠕蟲]]、[[特洛伊木马 (电脑)|特洛伊木马]]样本中检测到98.44%，并在1222款[[间谍软件]]和[[廣告軟體]]中检测到90.95%。它还检测并清除了所有25种Rootkit，并没有误报。{{r|Whitney 2-Oct-2009}}2010年6月到2013年1月之间，AV-TEST共测试了MSE14次；其中11次，MSE通过了AV-TEST超过杀毒软件行业平均水平的认证。{{r|av-test-01}}{{notetag|据AV-TEST称：（MSE）性能级别被看作达到了行业平均成绩。[...]家庭产品必须在18分总分中取得至少10分，并在每个测试类别中至少获得1分才能取得"AV-TEST CERTIFIED"认证徽章。{{r|CertifiedSecurity}}}}MSE2.0于2011年3月通过认证。产品得到了保护分数6分中的2.5分，修复分数6分中的3.5分和易用度6分中的5.5分。报告显示自2.0版开始，MSE可以发现所有[[WildList]]中的恶意程序样本，但缺少个人防火墙和防垃圾邮件功能，无法防禦基于网络的攻击。{{r|AV-TEST1}}在2012年4月的测试中，2.1版分别在保护、修复和易用方面取得3.0、5.5和5.0分。{{r|AV-TEST3}}4.0版于2012年6月在Windows 7 SP1（x64）测试，并分别在三方面取得2.5、5.5和5.5分。{{r|AV-TEST4}}2012年10月，在对MSE4.1的测试中，产品因它在三方面分别取得1.5、3.5和5.5分而失去了AV-TEST认证。{{r|cert-is-lost|AV-TEST-Cert-loss}}

AV-TEST的2011年年度评价中，MSE在保护方面排名最后，修复和易用度分别排第七和五。{{r|av-test-02}}2012年的评价中，保护功能排名最后，易用度排名第一，但它失去了认证，没资格得到易用奖。{{r|av-test-03}}2013年6月，MSE得到了最低的保护得分0。{{r|AV-TEST-rock bottom}}

随着时间推移，微软大幅提高了MSE的检测能力，在AV-TEST于2018年2月的最新测试中，MSE在“对[[零日攻击|零日恶意软件攻击]]的保护，包括网络和电子邮件威胁（真实世界测试）”和“对过去4周内发现的广泛和普遍的恶意软件的检测（AV-TEST参考集）”类别中，检测了100%恶意软件样本，为其赢得了AV-TESTS的“顶级产品”奖。{{r|av-test-04}}

== 市场份额 ==
2010年9月29日，初始版发布已满一年，微软宣布MSE有超过3000万用户。{{r|TechRadar}}2011年1月，OPSWAT发布的安全行业市场份额分析（{{langx|en|Security Industry Market Share Analysis}}）称它为世上極流行的杀毒软件，{{r|OPSWAT-June-2011}}占全球市场的10.66%{{r|OPSWAT-June-2011|p=5}}和北美市场的15.68%{{r|OPSWAT-June-2011|p=4}}。该报告还显示微软凭借17.07%的市场份额成为北美市场第一{{r|OPSWAT-June-2011|p=3}}以及世界第四的杀毒软件供应商{{r|OPSWAT-June-2011|p=2}}。

PCWorld的邓约翰（{{lang|en|John Dunn}}）分析报告后注意到，免费杀毒软件正在成为新宠：“毕竟，免费杀毒软件已出現了许多年，但往往將它们视为付费软件的穷亲戚。”他认为MSE影响用户选择免费杀毒软件。{{r|Dunn}}

2011年9月，OPSWAT有报告指出MSE市场份额繼續增加，成为世界第二流行的杀毒软件，且在北美最流行。{{r|OPSWAT-September-2011}}OPSWAT在2012年3月的报告称产品維持了過去在杀毒软件市场上的地位，全球市场份额提高了2%，北美則提高了3%。{{r|OPSWAT-May-2012}}CNET News的塞思·罗森布拉特（{{Lang|en|Seth Rosenblatt}}）评论产品市場份额在2010至2012年間從7.27%增长到10.08%时说：“去年推出的轻量级安全套装促使了爆发式增长”。{{r|Rossenblat}}

== 恶意软件模仿 ==
MSE流行使不少模仿它外观的恶意软件出现。2010年2月，网上出现自称“Security Essentials 2010”的[[流氓安全软件]]。微软命名它为“TrojanDownloader:Win32/Fakeinit”，但它外观並不似微软产品。{{r|Wood|Microsoft 2-Apr-2009}}它于2010年11月再次出现，并自称“MSE2011”。{{r|NewYear}}更危险的流氓软件在2010年8月出现，名为「Rogue:Win32/FakePAV」或「Unknown Win32/Trojan」，它非常似MSE，并用复杂的[[社会工程学]]，藉五款虚假的防毒软件欺骗用户并感染系统。它可终止并禁止启动156种不同程序，包括[[注册表]]编辑器、[[命令提示字元]]、[[Internet Explorer]]、[[Mozilla Firefox]]、[[Opera浏览器|Opera]]、[[Safari]]和[[Google Chrome]]。{{r|Foster|MSRT|Encyclopedia}}
