如今，获取电子邮件附件很常见，因此，您必须学会小心处理它们，因为它们通常被用作向您的计算机传递恶意软件有效负载的载体。让我们来看看您在打开电子邮件附件时需要采取的一些预防措施。

带有恶意文件附件的未经请求的邮件的典型案例通常具有以下性质：

1. 您中了奖品或彩票，您需要在附件表格中填写详细信息
2. 您的业​​务订单已被取消或您收到了新订单
3. 谈论一些发票的电子邮件
4. 在家工作赚钱
5. 缓解疼痛或减肥计划
6. 来自银行^(Bank)、PayPal等的信函，要求您按照附件提交详细信息，否则帐户将被冻结等。

如果您使用的是优秀的防病毒软件^{(good antivirus software)}或Internet 安全套件^{(Internet Security Suite)}，恶意软件文件很可能会在下载到您的计算机后立即被自动隔离。如果您使用的是Outlook之类的电子邮件客户端，那对您来说还是更好的。

如今，大多数常用的电子邮件服务提供商^{(commonly used email service providers)}（如Outlook或Gmail）都有很好的过滤器，可以将此类电子邮件（尤其是那些拥有 .exe 或带有 exe 文件的压缩文件夹）自动移动到垃圾^(Junk)文件夹。

但是，您需要时刻保持警惕！

打开电子邮件附件时的注意事项

首先，永远不要点击您不期望的电子邮件附件。

接下来，检查发件人的电子邮件 ID。是来自你认识的人吗？

但即使电子邮件 ID 看起来很熟悉，电子邮件欺骗和其他黑客攻击也可以很容易地使用其他人的邮件 ID 发送电子邮件。

如果您的服务或软件提供，请设置您的电子邮件首选项，以便附件不会自动下载或打开。这通常是默认设置——但肯定不会有什么坏处。确保在 Windows 中正确配置附件管理器。

^(Hover)将鼠标指针悬停在附件上。它是一个.exe文件吗？在这种情况下，根本不要下载它。它是Office .doc 文件吗？然后再次不要单击它，因为它可能是宏^(Macro)病毒。现在，如果它有其他文件扩展名怎么办？即使是这种情况，您也需要采取足够的预防措施，因为恶意软件编写者可以使用任何文件扩展名轻松伪装病毒、木马或勒索软件文件。

如果您根本无法控制自己的好奇心并且想要查看电子邮件附件，请不要选择打开选项，而是选择下载^(Download)选项。将文件下载到您的计算机后，右键单击它并使用防病毒软件进行扫描。

如果您希望安全，请将其上传并使用任何这些免费的在线防病毒扫描程序对其进行扫描^{(free online antivirus scanners)}。

请记住^(Remember)，如果您下载的附件文件被证明是恶意的，它可能会感染您的文件，甚至清除您的数据或将其锁定（如果它是勒索软件文件）。因此，您确实需要确保在打开之前下载的文件。

Precautions to take when opening email attachments

Getting email attachments is a common thing these days, and it is, therefore, imperative that you learn to handle them with care, as they are оften used as a vector to deliver a malware payload to your computer. Let us take a look at some of the precautions you need to take when opening emаil attachments.

The classic cases of unsolicited mail with malicious file attachments are usually of this nature:

1. You won a reward or a lottery, and you need to fill in the details in the attached form
2. Your business order has been canceled or that you got a new order
3. Emails that talk of some Invoices
4. Work from home and earn money
5. Pain relief or weight-loss programs
6. Letter from a Bank, PayPal, etc., asking you to submit details as per the attachment or else the account will get blocked, etc.

If you are using a good antivirus software or an Internet Security Suite, the chances are that the malware file will be automatically quarantined as soon as it is downloaded to your computer. If you are using an email client like Outlook, still better for you.

These days most of the commonly used email service providers like Outlook or Gmail have good filters in place that move such email – especially those who have .exe or compressed folders with exe files – automatically to the Junk folder.

But nevertheless, you need to be alert at all times!

Precautions to take when opening email attachments

First and foremost, never click on an email attachment that you were not expecting.

Next, check the email ID of the sender. Is it from someone you know?

But even if the email ID looks familiar, email spoofing and other hacks make it very easy to send email using someone else’s mail ID.

If your service or software provides, set your email preferences so that attachments don’t download or open automatically. This usually is the default setting – but never hurts to be sure. Make sure that you configure the Attachment Manager in Windows correctly.

Hover your mouse pointer over the attachment. Is it a .exe file? In that case, simply do not download it. Is it an Office .doc file? Then again do not click on it as it could be a Macro virus. Now, what if it has some other file extension? Even if this is the case you need to take sufficient precautions as malware writers can easily disguise a virus or a trojan or a ransomware file using any file extension.

If at all you cannot control your curiosity and you want to check out the email attachment, do not select the Open option but instead select the Download option. Once the file has been downloaded to your computer, right-click on it and scan with your antivirus software.

If you wish to be safe, upload it and get it scanned with any of these free online antivirus scanners.

Remember, if the attachment file you download turns out to be malicious, it could infect your files and even wipe out your data or lock it, if it is a ransomware file. So you really need to be sure that the file you downloaded before you open it.

My rule? If in doubt, I don’t. Period.
