I work in architecture and spend my days downloading files like PDFs, DXFs, and JPEGs from various websites. I also often need to transfer data using a flash drive. I'm worried about the risks of downloading random files and wonder if there's a way to do this securely. Am I destined to encounter malware, or are there practical steps I can take to stay safe?

Using Windows 11's built-in sandbox is a good choice too. It operates a lot like a hypervisor, meaning anything you run in there is discarded once you close it, so you can play around without worries.
You're not doomed! Just establish a solid routine. Always use a standard user account for your everyday tasks, keep your Windows and browser up-to-date, and don't forget to scan every download before you open it. For anything from unknown sources, consider using a sandbox or an isolated virtual machine to try opening the files. That way, you only move the clean ones to your main system.
Plus, tools like VirusTotal can help you check files for any malware before you open them. And hey, just keeping your operating system and software updated significantly reduces the risk of infection.
If you're really concerned about malware, you could even get a secondary machine—like a dedicated laptop or tablet—just for your architecture work. Keep it isolated from your main network to minimize risk.
Ultimately, good PC hygiene is crucial. If your PDF viewer is up-to-date and doesn’t execute unsafe content, then even if there’s malware in a downloaded file, it won’t be a threat.
