How To Scan Emails For Viruses in 2021 (EASY & SECURE)
Virus-infected email attachments have existed for decades, but they are far from obsolete. In reality, instead of using browser-based tools like Gmail, millions of computer users around the world use desktop email software. As a consequence, rather than simply reading an email online, you’re exposing your operating system to downloads any time you open it.
What exactly is the issue? When you use them, you run a much higher risk of opening cybersecurity risks.
For computer users, antivirus software that scans attachments for viruses is important. It can not only protect you from malware, but it can also prevent spam email and corrupted attachments from reaching your professional or personal networks by checking your outbound messages en route to the mail server. It’s possible that this would save your reputation.
What is Email Virus?
An email virus is a malicious code that is distributed in email messages and can be triggered when a user opens an email attachment, clicks on a connection in an email message, or communicates with the infected email message in some other way.
The majority of email viruses spread by sending a malicious message or attachment to everyone in the victim’s address book. Viruses may be packed and delivered in a variety of ways. Any of them can be easily identified as malicious due to their illogical subject lines, suspicious sender, or a variety of other header fields and body material. Recipients will often find it difficult to recognise individual email messages containing malware, as these messages represent a significant amount of effort on the part of the malicious actor to make the email appear as if it came from a known and trusted sender. This is especially true as phishing attacks are used to carry out business email compromise attacks.
Phishing attacks, in which hackers send out malicious email messages that seem to have been sent from approved outlets such as internet search pages, social media, the victim’s bank, or even coworkers and friends, are the most common causes of email viruses. The attacker’s goal in such situations is to trick users into disclosing personal information like the victim’s full names and addresses, usernames, passwords, payment card numbers, or Social Security numbers. Spam and malware-laden email messages are also considered one of the most powerful methods of social engineering used by hackers to distribute viruses, infect users, and target the networks of their victims’ businesses.
Types of Email Viruses
- Ransomware: encrypts the victim’s data and then requests a fee to recover it, usually via email. Ransomware attacks are typically motivated by financial gain, and unlike other forms of attacks, the target of a ransomware attack is usually informed that an exploit has occurred and given instructions about how to recover. Payment is usually requested in a virtual currency, such as bitcoin, in ransomware attacks to protect the cybercriminal’s identity.
- Phishing: Phishing is a type of fraud that uses psychological manipulation to persuade victims to disclose confidential information such as login data or passwords, which criminals then use or sell for malicious purposes. A phishing attack usually consists of an authentic-looking sender and a socially engineered post. Many email recipients mistakenly assume the message is from a trusted source, and they open infected attachments or click on malicious links as a result.
- Spoofing: Because email protocols lack effective mechanisms for authenticating email addresses, hackers may use addresses and domains that look very similar to legitimate ones, fooling victims into thinking the fake emails they receive are from a trustworthy person.
- Whaling/Business Email Compromise: Business Email Compromise (BEC), also known as “whaling,” is a form of email compromise that focuses on an organization’s biggest fish. An attacker sends an email to someone in the company who has the ability to conduct a financial transaction in this form of social engineering scam. The email pretends to be from the CEO or another approved individual, and it requests an immediate financial transaction, such as a vendor payment, wire transfer, or direct deposit.
- Spam: Despite a variety of efforts to screen out unwanted emails, spam appears to be a major problem for businesses. As the most common form of spam is simply considered a bother, spam is also commonly used to spread malware. Since ransomware is most commonly distributed via spam, all organisations should carefully evaluate spam for malicious intent.
- Criminals: who commit the most serious data breaches often use compromised user credentials. One powerful tool used by offenders to acquire passwords and IDs is the use of a keylogger. When victims unwittingly click on a malicious connection or attachment in an email, they become infected.
- Zero-Day Exploits: A zero-day vulnerability is a security flaw that the software developer is unaware of. Hackers take advantage of the security flaw until the vendor develops a patch. Hackers use zero-day attacks to gain unauthorised access and steal confidential information. They are usually distributed through malicious emails.
- Social Engineering: use social engineering to gain trust before stealing sensitive information or user login credentials. A computer criminal poses as a trustworthy person and engages in a conversation to gain access to a company’s network in a social engineering assault. The perpetrator deceives the victim into sharing passwords, identification numbers, and other confidential details, or pressures them to make a fraudulent transaction without their knowledge.
How to Protect Yourself From Spam and Email Viruses?
To prevent an email virus from infecting your client system or network, follow the advice below:
- Antivirus software should be used.
- Check for malware in all attachments.
- Avoid opening potentially harmful attachments, such as PDF files, that might have been sent to you in an email message from an unknown sender.
- Do not click on links given in email messages, and be wary of phishing emails that appear to come from trusted sources.
- Update and patch your email client, operating system, and web browser.
- Any executable files sent as email attachments should not be opened. Attackers try to mask these files by giving them two extensions, such as image.gif.exe, but.exe is an executable file that will run automatically.
- Don’t send out your email address to unsecured websites.
- Even if the site is safe, malware and viruses will capture your email address, making it easy for them to send you a fake email containing a virus.
- Using a text preview in your preferred email service will help you avoid spam and email virus attacks. Content previews allow you to get a quick glimpse of the email’s content without having to click on it to find out what it’s about.
- If you receive an email from an antivirus programme informing you that your machine has been compromised, always double-check the details with your antivirus software before opening the email.
- Email correspondence is less likely for these applications than interface messages.
3 Ways an Email Virus Infects Computers
To keep email viruses at bay, individuals and organisations must devote more resources to email security. While an email virus appears to be easy, its ability to harm your computer should not be underestimated. Given the possibility that the email virus was created by a cybercriminal, further email defence is needed.
Consider what parts of an email virus could hide to better protect yourself.
How an Email Virus Is Delivered to Your Email?
Top 3 Ways an Email Virus is Delivered to your Email
Phishing uses an email virus. A Virus in an Email Attachment
In the body of the email, there is an email virus.
1. An Email Virus in Phishing Email
An email virus may be just the start of a targeted attack on your personal information. Some hackers might be looking for confidential information in your account or in a database to which you have access. You’ll need to increase your diligence in addition to improving your email security. The hackers may have conducted research and used social engineering to create a phishing email to obtain your personal information.
In this case, self-awareness and gut instinct are needed in addition to email defence. If you don’t know how a company got your email or if you don’t know the person who sent it to you, don’t open it because it could contain an email virus.
Keep an eye on the web address in the email to see if it’s the same one you use to log in. Check with the organisation to see if their domain has changed if the email address has changed. Since address changes can often be so minor, you’ll need to be more meticulous than normal. A little extra caution is preferable to additional email security.
If you know the email is a hoax, please delete it and don’t forward it to someone else. Make it a habit to be very careful about what messages you forward, so you can help secure other people’s email in any way. This also reduces the chances of an email virus spreading.
2.Virus in an Email Attachment
The email attachment is the most popular way for an email virus to spread. Again, for better email virus security, be careful and do not open any attachments if they are not from anyone you know and trust. Even if you trust the sender, you can double-check the attachment’s file name.
Since email viruses often take the form of executable files, be wary of anything that ends in the following extensions:
3. An Email Virus in the Body of the Email
If your machine has antivirus software, you can download the message but not open it. Check for email viruses with your antivirus software. This will assist you in cleaning the file. However, your company or you can get Comodo’s Antispam Gateway for the best email security. This programme combines three layers of email security in a command console: containment technology, which isolates email viruses and allows them to run in a secure environment within your device, and advanced filters and algorithms, which weed out threats inside your email. Is there a safer way to secure your email?
Attachment Virus Scanning, Step-by-Step
I strongly advise downloading third-party antivirus software if you use a desktop email client and want to search attachments for viruses. While Windows’ built-in antivirus security can detect a wide range of threats, commercial antivirus vendors usually provide the most up-to-date definition databases and provide real-time protection.
What Software Should I Use?
Norton: Norton’s goods search outbound and inbound email in both directions. In supported email clients, Norton can also build a Norton AntiSpam folder to keep spam out of your inbox.
Comodo: Comodo has a range of products aimed specifically at enhancing email protection. This includes a free antispam gateway that blocks spam, phishing emails, and malicious attachments on IMAP and SMTP servers using cloud-based filtering.
Comodo Antivirus for Linux. also has a built-in mail gateway, making it one of the few email protection systems that work with Linux.
AVG: AVG Email Security comes with a built-in gateway that encrypts messages sent from any third-party email server. The tool also allows users to search encrypted messages, which is a big plus for those who use encryption and security software like Pretty Good Privacy (PGP).
Scanning Email.Is Needed for Desktop Users
Although I appreciate the ease of browser-based webmail platforms as much as the next person, there are occasions when using a dedicated piece of email software is literally unbeatable.
Email Scanning Is A Must for Desktop Users
computers with viruses and malware via corrupted attachments. Every desktop email consumer should instal an antivirus programme that includes email scanning.
Do I need to scan my emails for viruses?
Viruses are computer programmes that trigger problems if they get into your computer. Email messages are a popular way for them to gain access to your phone.
Viruses that affect Linux-based computers are uncommon, so you’re unlikely to get one via email or other means. If you receive an email that contains a virus, it will almost certainly have no impact on your device. As a result, it’s unlikely that you’ll need to search your email for viruses.
You can, however, check your email for viruses in case you accidentally forward a virus to someone else. For example, if one of your friends has a virus on his Windows computer and sends you a virus-infected email, and you then forward that email to another friend who also has a Windows computer, the second friend can contract the virus. You might use an anti-virus programme to search your emails to avoid this, but it’s impossible because most people who use Windows and Mac OS already have anti-virus apps.
