How to Scan Gmail for Viruses?
When an email message arrives, when you open an email, and when you send an email message, your Gmail account runs virus scans automatically. If Google Gmail detects a virus or a suspicious attachment, it can refuse to deliver the email to your inbox.
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 organizations 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 unauthorized 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 program 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.
