How To Scan Email Attachments For Virus / Malware
- Removes Malware which Antivirus cannot
- Protects from Ransomware Attacks
Email is still the primary means of communication for most people despite the popularity of social media and messaging applications. In 2018, there were over 3.8 billion email users around the world. And, it is projected to increase to 4.4 billion by 2023.
That is why email remains one of the major thoroughfares for malware and viruses. Attaching malicious software in emails can turn an innocent message into a gateway to your computer. While people are getting better at recognizing warning signs of questionable emails and attachments, hackers are getting smarter as well.
Thankfully, it is very simple to protect your devices from threats coming from email attachments.
Symptoms Of Virus Infections
Well, now that we understand how hackers mainly get access to our computer networks and systems, we must then understand how to tell if a computer is potentially infected with a virus.
There are various ways in which the computer will start to misbehave and can be significant indicators that your computer is infected with diagnoses early you have the potential to stop the potential hack from happening and keeping your computer safe. Some ways you will notice the computer misbehaving are:
Is Scanning To Email Secure
Not necessarily. When you use the scan to email function, you cant be certain if the email was sent appropriately unless you have access to the email address yourself.
Also, multifunction printers send emails in clear text by default. These may be intercepted by third parties who are also connected to the same WiFi network as your printer.
This is why you should only use the scan to email function on your printer for non-confidential documents that you can personally verify were sent properly.

How Do Hackers Compose Their Emails
Hackers emails would either draw or seek attention from users in the region they want to reach. This is referred to as social engineering. It can be defined as a strategy in which people are duped into divulging information they would not usually divulge.
These hackers attempt to obtain a variety of information however, when your information is targeted, hackers are more likely to attempt to obtain your banking information, passwords, or access to your computer network.
Hackers can gain access to your machine in a variety of ways, depending on the hackers goals. If theyre after your banking details, theyll send you an email that looks like it came from a bank, asking you to log in to something.
With the recent outbreak of the worldwide coronavirus, hackers can disguise themselves as a news document that, once downloaded, infects the device.
Trying to compile all of the ways a hacker might hack will be useless, as they would always come up with new ways. The only way to stay ahead of the hackers is to change some aspects of communications, such as the sender, the language used, and be cautious about opening emails from contacts you are unfamiliar with.
You can also inspect the URL links by hovering your mouse over them and looking in the bottom left corner of your web browser you should see the URL to which youll be redirected. Do not open it if it ends in.exe,.js, or.zip.
How To Add Documents To An Email From A Scanner
When you scan a document or photo, you can send the scanned item to others via email as an attached file. If your scanner does not allow you to directly email the item, use Windows Fax and Scan, a free Windows utility. You can automate the process if you share documents frequently this way.
Type the email address of your recipient in the “To” field. If you want to send the scanned document to multiple recipients, enter their addresses in either the “To” field, “Cc” field or “Bcc” . Separate each address with a semicolon.
Enter a title for your message in the “Subject” field or leave the default in. Type a message in the main body area. Click “Send” to send the message.

Should You Use The Scan To Email Feature Of Your Printer
Scan to email may look like a quick and effective way to scan a document and send it online. And it is, just not for every document and recipient.
One of the main disadvantages of using the scan to email feature is the risk that the document wont reach its recipient.
When youre using the scan to email feature, its harder to check that the email address youre entering is correct because you may not receive an error message if you entered it incorrectly. You wont receive any warning if the intended recipient has changed their email address or if their inbox is full either.
Recipients also cant reply to a message delivered from a printer as the return email address will show as a no-reply address. You can rarely customize your message, and you wont hear back from recipients if they try to contact you using the email address on the message.
If you want to use the scan to email feature, you should only do it when you can personally confirm that the email reached its destination, and you should only use this function with documents that arent very important as they might not get through on the first try.
So, what should you do instead?

How Malware Is Spread Through Email Attachments
Before viruses that spread through email attachments can infect your computer, you must first download an infected attachment. You’d think that most users would simply not download email attachments from senders they do not trust, but it’s not that simple. Scammers often hack into users’ email accounts to send malicious attachments to their contacts.
Today’s hackers have advanced software for guessing common, name- and birthday-based passwords that allows them to access hundreds or even thousands of email accounts. What this means is that you can actually receive an email from a good friend or family member with a dangerous email attachment. While the malicious email attachment was sent from your friend’s account, your friend did not send the email… the person who hacked into his or her account did. However, users are inclined to trust the contents of emails from friends and family.
Second, many email attachment scams come from senders who pose as banks or other authoritative entities, emailing you about an issue with your account. These messages say something to the tune of “There is a problem with your account at XYZ . Please open the attached file to view your balance or statement, credits or monies owed and so forth.” Don’t do it.

Tips On Sending Attachments
The following are important points to consider when sending any attachment through e-mail.
- It is common courtesy to send only one to five attachments in a single e-mail. If you have more than five pictures, we suggest you post them online and send a link to that site, or compress all the files into one file.
- If you want to send a video through e-mail, it’s a better idea to send a link to the video instead.
- To send a file larger than 25 MB, we suggest you post it using one of the services mentioned above as most Internet e-mail services have that as their limit. For more information, see our page on how to send big attachments.
- Consider using an image editor to reduce the size of images. Images often take up a considerable amount space. Not only does this cause longer download times, but it reduces the number of images you can send.
- You may attach multiple pictures at the same time by holding down the , and then clicking each file individually.
- You can drag-and-drop attachments into the body of an e-mail message.
Why Can Email Attachments Be Dangerous
Some of the characteristics that make email attachments convenient and popular are also the ones that make them a common tool for attackers:
- Email is easily circulated – Forwarding email is so simple that viruses can quickly infect many machines. Most viruses don’t even require users to forward the email–they scan a users’ computer for email addresses and automatically send the infected message to all of the addresses they find. Attackers take advantage of the reality that most users will automatically trust and open any message that comes from someone they know.
- Email programs try to address all users’ needs – Almost any type of file can be attached to an email message, so attackers have more freedom with the types of viruses they can send.
- Email programs offer many “user-friendly” features – Some email programs have the option to automatically download email attachments, which immediately exposes your computer to any viruses within the attachments.

Why Scan And Email Documents
The process of scanning documents and emailing them is faster, more secure, and cost-efficient. Businesses are adopting digital documents as the new norm to help lessen their carbon footprint, save money, and speed up business processes.
Mailing documents doesnt ensure the recipients will get them. And waiting weeks to get signed documents back only slows down processes that would otherwise take hours to perform using email.
If this interests you, then learn more about scanning documents using your mobile or desktop device. Or better yet, start creating documents and converting them into PDF. This way, you can eliminate the use for paper altogether!

Never Open Email Attachments Marked As Spam
While it is safe to open any emails, you shouldnt click any links or open any attachments in emails marked as spam.
Unless you are using very old software, you wont get a virus just by opening an email anymore. This is because most viruses require you to take some sort of action in order to infect your computer these days.
Disable Email Attachment Scanning In Windows Defender
Currently one of the operations that we do most with our computer is to use our favorite email client. It is certainly a widely used method to send different types of documents as an attachment. Surely we have noticed on more than one occasion that when we are about to open any attached file, Windows will take care of analyzing it previously either with Microsoft Defender or another antivirus, something that some users can be annoying.
If we are users who constantly receive emails with attachments for work reasons, we find ourselves with the annoyance of having to go through the antivirus every time we want to access them. This is done for our own safety, although it may not be to our liking.
