How to Download Files Safely from the Internet

Downloading files and programs from the internet is convenient but also poses serious malware risks. As an experienced cybersecurity professional, I want to provide comprehensive, friendly advice to help you protect yourself when grabbing files online. By taking the right precautions, you can avoid downloading viruses, ransomware, spyware, and other threats that could harm your devices and data.

The growing threat of malware from downloads

Let‘s start by examining why safely downloading files matters in today‘s connected world. Malicious programs are everywhere online, and infections from unsafe downloads have been rising. Symantec reports that ransomware infections alone spiked by 105% in 2021. The total damage caused by malware exceeded $20 billion globally last year.

With fast internet speeds, it‘s tempting to quickly download programs and convenient. But that convenience comes with risks if you don‘t take the proper security measures. Don‘t let your guard down – the dangers are real.

How to know if a download site is safe

When looking to download files and programs, your first step should be verifying the safety of the website you‘re using. Here are the top things to check:

Use sites that start with HTTPS: The S in HTTPS stands for "secure" and means traffic is encrypted. HTTP sites have no encryption and are prone to eavesdropping.

Check for a padlock icon: Browsers display padlocks when an SSL certificate is detected. This validates the site‘s identity.

Avoid HTTP sites: HTTP has no encryption at all and is not considered secure. Only use HTTP as an absolute last resort.

Examine the domain carefully: Domains like "" or "" are fake despite looking real at first glance. Double check for typosquatting.

Stick to well-known domains: .com, .org, and .net domains are generally the safest options. Newer TLDs like .site or .app often indicate shady sites.

Download directly from official sources when possible: The official website of a software vendor is typically the most trustworthy place to download programs.

Comparison of Top Antivirus Programs

Antivirus Software Malware Detection Phishing Protection Firewall VPN
Norton 360 Excellent Yes Yes Yes
McAfee Total Protection Excellent Yes Yes Yes
Bitdefender Antivirus Plus Excellent Yes Yes No
AVG AntiVirus Free Good No Yes No

This table compares key security features provided in leading antivirus tools. Products like Norton 360 offer full protection.

Following these best practices helps avoid malicious files masquerading as legitimate downloads. Now let‘s look at steps to take once you‘ve vetted a site and are ready to actually download files from it.

Verify files before opening with antivirus scans

Anytime you download a new program or document, you should scan it for malware before opening. Here are some tips:

Use a reputable antivirus program: Top options like Norton, McAfee, and BitDefender all automatically scan downloads.

Manually scan files: Right click downloads and choose "Scan with antivirus" for an extra check.

Rescan after opening: Sneaky malware can evade initial scans. Do a follow-up sweep for good measure.

Update your antivirus regularly: Out-of-date virus definitions leave you vulnerable to new threats. Set auto-updates.

Antivirus scans act as the last line of defense to catch any risks. Think of it as sniffing food before eating it to avoid biting into something nasty!

Check file extensions before downloading

Take a quick look at the file extension before downloading anything. The extension indicates the file type and should match what you expect:

  • .PDF for Adobe Acrobat documents
  • .DOC or .DOCX for Word documents
  • .PNG, .JPG, or .GIF for image files

Unusual extensions like .EXE on documents are a red flag. Double check extensions against online databases if you‘re unsure. This simple check goes a long way towards avoiding malware disguised under bogus file formats.

Use download reputation scanners

Tools like VirusTotal aggregate results from dozens of antivirus engines to scan files and URLs. Upload a questionable download and see if multiple scanners flag it as dangerous.

VirusTotal and similar services also check download reputation. Files known to be malicious will get caught even if the contents appear clean. Think of it as running a background check on downloads before trusting them.

Safely torrenting files

Peer-to-peer (P2P) torrenting lets you download files hosted on other users‘ devices instead of a central server. Torrenting itself is legal, but can be used to share copyright-infringing material. Sticking to open source content avoids ethical issues.

Safe torrenting requires taking these precautions:

  • Use a trustworthy torrent client like qBittorrent instead of shady apps
  • Check comments for mentions of malware
  • Scan downloaded files with antivirus before opening
  • Use a VPN to hide your IP address and encrypt traffic
  • Avoid questionable torrent sites and stick to reputable ones like RARBG

Following good practices keeps you safe and avoids legal risks when using torrents.

Disable auto-downloads in your browser

Browsers will automatically download files from clicked links and browser exploits. Disabling auto-downloads prevents malware from instantly infecting your computer if you accidentally click something dangerous.

It takes just a minute to adjust your browser settings:

Chrome: Settings > Privacy & Security > Site Settings > Automatic Downloads

Firefox: Settings > General > Downloads > "Ask each time"

Edge: … > Downloads > "Ask me what to do"

Safari: Preferences > General > Uncheck "Open ‘safe‘ files after downloading"

These settings give you control and help block drive-by malware attacks. I recommend disabling auto-downloads in all your installed browsers.

Only download on secure networks

Public Wi-Fi networks are risky places to download files since they are easy to snoop on. Instead, only download on your home network protected by a password or when using a VPN. This avoids man-in-the-middle attacks.

If you need to grab a file while out, activate your VPN app to encrypt traffic. Never access financial or sensitive accounts on public Wi-Fi either without a VPN.

What to do if you download malware

Despite your best efforts, malware might occasionally slip through defenses. If your antivirus detects an infection or you notice suspicious system activity, take these steps:

  • Isolate the infected device from other devices and networks immediately
  • Use your antivirus to clean the infection or do a full system restore
  • Change all passwords from the infected device once disinfected
  • Scan other connected devices in case the malware spread

Acting quickly minimizes damage when dealing with malware. Don‘t take chances and assume infections will resolve themselves.

FAQ about safe downloading practices

Is it safer to download on iOS or Android?

Apple‘s tight control of the iOS App Store makes it harder for malware to get published there. However, Android malware does exist on Google Play, so be cautious and use antivirus apps on either platform.

Can you get malware from image files?

Yes, image formats like JPG and PNG can potentially hide malicious code in their encoding. Always scan them.

Should I avoid EXE files from unofficial sources?

Yes, EXE files carry heightened risks since they can install programs. When possible, only download EXEs from official developer sites or verified third-party app stores.

Can PDFs contain viruses?

Unfortunately yes. PDFs are commonly used by hackers to distribute malware through exploitable vulnerabilities in Adobe Acrobat. Scan all PDFs with antivirus before opening.

What are the risks of macro viruses in Word and Excel?

Microsoft Office files with macros enabled can execute malicious scripts. Disable macros in your Office settings to avoid this threat.

The bottom line

By implementing all the tips provided above, you can confidently download files while avoiding 99% of malware threats.
