The Best Way to Scan Emails for Viruses in 2020
In terms of how we rely on email as a communication tool in both work and personal life, it has evolved. Companies all around the world have battled to keep emails virus-free, but they are still vulnerable to attacks and one of the ways hackers get access to computer systems.
Email attacks can drain data from a cooperating organization’s or company’s server and demand a ransom, as well as steal banking information and block other user’s access to the network or computer systems. Email viruses and malware, according to Verizon, were to blame for their data leak in 2017.
Email viruses are also dangerous since they can be used by both professional and amateur hackers. Regardless of the Hollywood cliché of hackers as MIT geniuses with particular computer talents, a hacker is motivated by a monetary reward at the end of a hack. Why would they need to go to MIT when they can get the same outcomes with a few basic abilities and an email hack?
As a result, everybody using a computer or an internet device must guarantee that they are protected against any type of email virus. Fortunately, protecting your devices against email viruses is not as difficult as it may appear. All you need to know is how hackers use emails to catch users off guard and propagate viruses; once you understand that, the rest is simple.
How Do Hackers Compose Their Emails?
Hackers’ emails will either attract or seek attention from users in the area they want to access. This is referred to as “social engineering.” It can be described as a strategy in which people are duped into divulging information they would not normally divulge.
These hackers attempt to obtain a variety of information; however, when your information is targeted, hackers are most likely attempting to obtain your banking information, passwords, or access to your computer network.
Hackers can gain access to your computer in a variety of ways, depending on the hacker’s goals. If they’re after your banking information, they’ll send you an email that seems like it came from a bank, asking you to log in to something.
With the recent outbreak of the worldwide coronavirus, hackers may disguise themselves as a newspaper that, if downloaded, infects the machine.
Trying to compile all of the methods a hacker could hack would be fruitless, as they would always come up with new ones. The only way to stay ahead of the hackers is to change key aspects of emails, such as the sender, the language used, and be cautious about opening emails from contacts you are unfamiliar with.
You may also inspect the URL links by hovering your cursor over them and looking in the bottom left corner of your web browser; you should notice the URL to which you’ll be redirected. Do not open it if it ends in.exe,.js, or.zip.
Ways Hackers Access Computers through Malicious Emails
This is a technique in which hackers try to persuade you to reveal information by tricking you into doing something you shouldn’t. Hackers may send emails in bulk in a trawl for victims, or they may use targeted email for a specific member of a firm, based on their study on the company’s organisational structure.
Phishing was once primarily targeted at consumers, but it has since developed into one of the most serious dangers to company security.
In some cases, phishing is carried out as a result of a state-sponsored attack or cooperation. The risk is greatest here, as the hackers have the means and support needed to carry out the attack.
According to Verizon, 23% of recipients continue to open scam emails. The majority of phishing emails are opened within the first hour of receipt.
Email phishing scams have recently evolved to involve the installation of malware on the victim’s machine as a secondary step of the attack. The most hazardous aspect of email malware attacks is that all it takes is one person to open these emails for an assault to take place. Furthermore, they are persistent, such that avoiding one risk opens the door to the possibility of other hazards occurring sooner or later.
Another phishing technique that has resurfaced is macro viruses, which are viruses written in the same language as software packages. This means that the virus does not require installation; rather, the virus begins its infection operations as soon as the infected software is opened. This type of infection was very common in the 1990s, and it has only just resurfaced. The five-million-dollar bitstamp bitcoin exchange hack is an excellent illustration of this type of attack.
Attachments posing as courier notifications resumes, or any other valid data will be sent as attachments to emails. When you first open the document, it will ask you to allow macros before it can execute. If this is done, the virus will be able to initiate an attack.
The difference is that macros contaminated computers in the 1990s. Currently, they serve as downloaders, allowing seas of malware to infiltrate the system.
They encrypt your data and demand a fee to restore it to you, which is usually provided via email. Ransomware assaults, unlike most others, are primarily monetary in nature, and if you pay the ransom, your information will be returned to the firm or user.
To avoid being tracked by hackers, most payments are made in the form of bitcoin.
Hackers take advantage of an email feature that is weak because it lacks effective means for validating email addresses. As a result, hackers can imitate legitimate addresses and domains to deceive users into visiting them.
Whaling/Business Email Compromise
Hackers target a company’s senior official, or “big fish,” who has certain powers within the corporation that hackers are interested in.
Business email compromise, often known as whaling, is the practice of attempting to entice the company’s top executives to make a transaction. In this case, the hackers will send an email posing as the CEO of another company or another high-ranking official, demanding a financial transaction or a vendor payment wire transfer or direct deposit.
One of the most common ways for hackers to gain access to your system is through spam. It remains a huge difficulty for organisations and companies to control, despite various initiatives to manage how unsolicited emails are handled.
While spam may appear to be a minor annoyance, it serves as a conduit for hackers to deliver malware to your computer networks. Viruses like ransomware are commonly distributed to businesses via spam, therefore it’s important to be cautious while dealing with spam emails.
Hackers exploit stolen data to gain access to systems using this method. Criminals that are involved in major data breaches will utilise stolen data credentials to obtain access to computer systems, as this will provide them more access and produce better outcomes.
When a person clicks on a fraudulent email, key loggers can steal ids and other sensitive information.
This is a vulnerability that the programme developer is unaware of. Hackers take advantage of this security flaw before the developer has a chance to address it. Zero-day assaults are commonly distributed by email, and hackers will acquire access to them to exploit sensitive information.
This is one of the cybercriminals’ strategies for gaining confidence before stealing sensitive information.
Hackers use social engineering to build confidence by impersonating trusted individuals and establishing a virtual relationship with the target through talks and other means.
The attacker will then persuade the target to reveal passwords, IDs, and other sensitive information, or to engage in fraudulent behaviour, whether deliberately or inadvertently.
Symptoms of Virus Infections
Now that we know how hackers primarily gain access to our computer networks and systems, we must also know how to identify if a machine is infected with a virus.
There are a variety of ways that your computer will begin to misbehave and can be important symptoms that your computer is infected. By diagnosing your computer early, you have the opportunity to prevent a potential hack and keep your computer safe. You’ll notice the computer’s misbehaviour in a variety of ways, including:
Pop up Ads
Are you constantly bombarded with advertisements on your computer, regardless of whether you’ve banned pop-up ads with your security software? You may be contaminated.
The pop-up adverts appear frequently, to the point that you are unable to do anything on the computer owing to the pop-ups, each of which instructs you to click on it.
If you click on the pop adverts, they will take you to other websites, where you will be bombarded with additional advertisements. If you experience any of these symptoms, your computer is likely infected with malware.
Is your computer acting strangely slow and lagging? Is this happening even if you aren’t running multiple applications that would otherwise cause computer lag?
You may be infected!
You may also be using a lot of intensive software that is chewing up your RAM; however, although this slows down the computer, viruses create tremendous lag, making even moving the mouse a difficulty.
If your computer crashes frequently, you could be infected.
When a virus infects a computer, the number of crashes increases to the point where it crashes at an abnormal rate.
If this happens, you should remove the viruses as soon as possible.
Slow Internet Connection
The internet may start to slow down. If you have a virus, this will happen.
You may test internet speeds, which should be enough; nevertheless, when you connect to the computer, the internet connection remains slow.
Missing Files or Applications
Do you require specific files or applications? Are you certain you didn’t delete any of these files? Some viruses, such as ransomware, encrypt your data or apps and demand a fee to decrypt them.
If you can’t find any physical evidence of the deletion, you should take steps to prevent any further data loss.
Disabled Antivirus or Firewalls
It’s a significant red signal if your antivirus or firewalls are disabled and you didn’t do it, nor did anybody else in your group. You’ve got to be infected.
Disabled firewalls or antiviruses are the most common entry points for malware and viruses, necessitating you to take extra care to avoid data loss.
Which Are the Best Software to Ensure You Are Free of Any Email Viruses?
Before we look at some of the finest programmes for scanning for email viruses, we’ll take a look at how to scan for viruses on MAC, Windows, and Android devices.
These methods will assist you in securing your devices from any malware or viruses that may be transmitted over email. It will also assist to reduce the risk of a user clicking on an email and revealing sensitive information to hackers.
Best Way to Scan an Email Attachment for Virus-IOS Devices
When it comes to IOS devices, such as the Mac, widespread thinking holds that computer viruses are rarely a problem. However, your Mac can get viruses and malware; the main difference is that malware detection and file quarantine capabilities are designed to make it less possible for you to download hazardous software.
With Snow Leopard (Mac OS 10.6), Apple included malware detection to the mac OS, as well as a quarantine mechanism for any app downloaded from the internet. The system employs code-signing certificates to ensure that software is legitimate, and it also instals frequent security updates that include databases of known Mac OS malware.
The system performs the following tasks:
- Quarantined apps display a dialogue box that reminds you where the software came from and whether you wish to use it. If they didn’t come with a code signing certificate, depending on your gatekeeper settings, you can get a notice saying the app can’t be opened because of the settings.
- If an app has malware that the system recognises, a warning will appear recommending that the programme be deleted.
This is why Macs are thought to be virus-free.
Tools You Can Use to Scan Email Viruses
This is similar to an AdWare medic, and it’s available on the Mac App Store or directly from the ClamXav website, where you may also give.
You set the app preference after you’ve downloaded and opened the app. It operates in such a way that it scans for viruses but just quarantines them. Certain setup settings are available in the app, including :
- This may be used to set up notifications and decide whether or not to check your email communications for malware and phishing.
- Quarantine—defines where harmful files should be quarantined.
- Exclude File is a feature that allows you to select which file types you don’t want to be inspected.
- Log files- for deciding whether or not to keep log files and examining them.
- Defining a plan for when you want the latest virus definitions to be downloaded and whether or not you want scheduled scans

Examine the list of attachments and uncheck the boxes next to any that you don’t want to be deleted. When you’re finished, press clean.
Virus Scanning for Windows Devices
Through firstname.lastname@example.org, you can get your emails tested for malware online.
The virus checks the attachment with various anti-malware tools and then sends it back to you as an email response.
The information you receive will be accompanied by the findings of numerous antivirus programmes that were run on the attachment.
Sending Attachments to Virus Total Works: A Step-by-Step Guide
You’ll need to compose a message that will be emailed to email@example.com.
As an attachment, save the questionable email. Next, right-click the item in Outlook and select Save As Attachment, then choose where you wish to save the email.
Create a new email and address it to firstname.lastname@example.org in the recipient field.
In the subject line, either type SCAN or SCAN+XML depending on what you want. This will produce either plain text or an XML version of the results.
After that, you’ll attach the stored email as an attachment and send it.
Another alternative is to send the suspicious email to email@example.com with the subject line SCAN.
The response time may vary depending on the number of queries on their server; but, you will not need to repeat the email because they will respond.
Scanning Viruses in Android Devices
On an Android smartphone, there appears to be no special way to scan emails for malware.
Because Android devices are compatible with other Windows apps when it comes to internet access, you can scan for viruses in the same way that you would with Windows. Copy and paste the email into a valid email scanner, then firstname.lastname@example.org using the same technique.
Nevertheless, your Android device can be infected by an email; however, you may check the phone or android device and delete any hazardous software that may have been installed.
You’ll need effective antivirus software to keep harmful emails from infecting your phone.
However, if you have already been infected, there are several actions you may take to wipe out the device.
Step 1: Go to the Google Play Store and download your preferred antivirus. Always read other people’s opinions and see what they have to say about it.
Step 2-open the antivirus app and sign up for an account before running a scan. The programme may ask for rights to access your camera contacts and other information, which you can grant or deny.
Step 3: Give the app a chance to search your phone for harmful malware.
Step 4-if the phone is infected with viruses, the programme will discover a remedy by selecting resolve, and the viruses will be quarantined or eliminated.
Step 5-If harmful software is detected during scanning, it is recommended to remove it.
There are a few procedures to follow if you want to manually uninstall harmful apps:
Step 1: Enable safe mode in your Android’s settings, which disables all third-party access. If all of the difficulties disappear, malware infections on the phone are to blame.
Step 2: Go to Settings and select the Manage Apps tab to figure out which programme is causing the issue. Check the download tab for any apps you’re not aware of, as well as those running in the background that you’re not aware of.
Step 3: Uninstall the software to get rid of it.
Step 4- Return to the settings and look for the security tab, then touch on the device administrator to see if the malicious app has any permissions. If it does, turn it off.
Step 5-if you are unable to remove the virus after running the scan and attempting to do it manually, you may need to reset the phone.
Apart from the methods outlined above, there are a plethora of other methods and programmes available for scanning emails across several devices. Please feel free to add more in the comments section below.
