Great question, ByTe-DEv! This is something everyone who uses email—basically all of us!—should understand. Let’s break it down:

Can Viruses Still Be Sent via Email Attachments?

Short answer: Yes, viruses and malware can definitely still be sent via email attachments, although modern protections have made it harder.

Here’s how it works:

  • Malicious attachments: Attackers commonly send files like .exe, .doc, .xls, .pdf, or even .zip files via email. If you open an infected attachment—especially if you enable macros or run an embedded script—malware may execute on your device.
  • Social engineering: Attackers often pretend to be someone you trust or say there’s an urgent issue (“Invoice overdue!”), tricking people into opening the file.
  • Fileless malware: Some attacks use documents with macros or links, launching scripts without a traditional downloadable virus file.

What About Email App Protections?

Modern email services (like Gmail, Outlook, etc.) use automated scanners to check attachments and links for known malware signatures as well as suspicious behaviors. They block lots of threats, but…

Limitations and Real-World Risks:

  • Zero-day & new threats sometimes evade scanners before definitions are updated.
  • Sophisticated phishing can trick users even if attachments seem “safe.”
  • Encrypted attachments (like password-protected ZIPs) often bypass scanning because the mail system can’t “see inside” them.

Are People Still Getting Infected?

Unfortunately, yes. Human error is always a weak link. When users are tricked into opening a malicious file—even by bypassing a warning—the infection risk is real.

How to Stay Safe

Here are a few practical tips to reduce your risk:

  • Don’t open attachments from unknown sources—even if they “look” legit.
  • Be wary of attachments that require you to enable macros or scripts.
  • Keep your operating system and software updated with the latest security patches.
  • Use antivirus software as a backup layer.
  • For parents worried about children opening risky attachments, something like mSpy is a great solution. It lets you monitor what’s being sent to your child’s phone, so you can step in before they fall for a scam.

Bottom line: Email attachment viruses are less rampant than they once were, but the danger is not gone. Tech helps, but vigilance is your best defense!

Hi ByTe-DEv,

Email attachments can still be a way for viruses and malware to spread, even though email providers and apps have gotten better at filtering out malicious files. It’s always a good idea to be cautious about opening attachments, especially from unknown senders.

A few key things to watch out for:

  • Attachments you weren’t expecting, even if they appear to be from someone you know. Their account may have been compromised.
  • Files ending in .exe, .zip, .scr, as these are common formats for hiding malware.
  • Any message that creates a sense of urgency or uses scare tactics to get you to open the attachment without thinking.

If you do need to open an attachment, make sure you have reputable, updated antivirus software running first. Consider saving the file and scanning it individually before opening.
