Gone are the days of buying CDs to download the latest software. Now when you need to update or install new programs, you get the files directly from a website.

The problem with downloading files is the risk of ending up downloading a nasty computer virus with those new files. Luckily, there are ways to tell whether a file is safe to download:

• The file extension matches common file types such as .txt, .pdf, .doc or .docx, .ppt, .mp3, .mp4, or .jpg.
• You’ve scanned the download link to ensure it’s legit.
• Your antivirus scanned and OK’d the file.
• Lots of other users have downloaded the file or left positive reviews.

Keep reading to learn how you can download the files you need without the malware you don’t want.

How to check if the download website is legit

When you go to a website, you want to be sure it’s secure. One thing to look for is that the website address begins with https:// instead of http://.

That extra letter means it’s a secure site. You can also look for a lock or shield icon, depending on your web browser, usually next to the web address. Downloading from any random site could be the fastest way to get a virus on your device. Here’s what to look for when checking for a legit site.

Download from the official source

When you download files, you want to use the official file sources. If you go right to the source, you avoid downloading a computer virus.

An example of an official source would be looking for the best antivirus programs, deciding you want to learn more about Norton, and then going to the actual Norton site to download the software.

Of course, it’s not always dangerous to use a third-party source. Many sites that host downloads are safe and don’t have malware. Some third-party sites that are commonly used to download software include:

If you can’t download from an official source, you can use a third-party site. But make sure you verify its trustworthiness:

1. Check the site’s About page to ensure it verifies software before sharing it.
2. If a site accepts software submissions, make sure it has a review process in place, such as Softpedia’s software review requirement.
3. Look for contact information such as addresses and phone numbers.

Heads up: Never download from a pop-up ad

Hackers like to use pop-up ads to spread malware, so you should avoid clicking on or downloading files from pop-ups. Sure, some pop-ups are from reputable companies, but because you can’t tell if a pop-up ad is safe, it’s best to avoid downloading from one. Instead, go to the official source to download your files.

Look for “https” in the URL

When you see https:// in front of a website address, it means the site is secure and more trustworthy than sites that start with http://.

Sites with https:// contain SSL certificates, which is short for secure sockets layer and is the technology used for securing an internet connection and keeping data safe.

SSL encrypts data transferred between you and the sites you browse. The encryption keeps hackers from reading private information you enter into a site, such as your credit card number or password.

Double-check the web address

A trick hackers like to try is using a website address that closely resembles the web address of well-known companies. For example, you could see a fake site with an address of Amaz0n.net.

If you aren’t paying close attention, you might click on the link and think you’re going to the official Amazon site, but instead, you’re sent to a fake site that likely hosts malware. This trick gets used frequently during the holiday season when you’re likely doing more online shopping.

Check the domain

Another thing you can look for when checking the web address is a generic top-level domain (TLD) domain such as .app, .xyz, or .online.

A TLD is everything after the dot in the domain name. The most popular TLDs are .com, .org, and .net — .gov and .uk are also commonly used.

If you spot a web address that doesn’t use one of the more common TLDs, use caution. It could be a reputable site, but try to verify it with the steps above before downloading from it.

Avoid using torrents

Torrenting is when you download or upload files from a network of other users’ devices. Rather than going through a central server, you use a random device. Torrenting is a popular way to share files that would normally cost money to purchase.

Using torrents isn’t technically illegal, but it may not be entirely ethical either. Some people consider torrenting a type of piracy because you could end up downloading unsanctioned copyrighted material, which is illegal. And because you’re downloading files from another anonymous user, it’s difficult to verify that person is sending you legitimate files and not malware.

At best, using torrents can be a gray area that may be best avoided.

How to know if a download is safe or not

Before downloading a file, you should check the website for security, but you also want to check the link for the download and the download itself.

There are a few different ways to do this, including using line checkers, virus scans, and file extensions. By implementing these tips, you can check the link for safety before you download any files.

Check the file extension

A file extension is simply the suffix at the end of your computer files, such as .jpg or .doc. It comes after the file name and will be around two to four characters long. Your operating system uses file extensions to identify the apps associated with them.

You can use websites that let you enter a file extension into their database to check for validity.

You can also note the file extension before you download it by clicking the download button but not confirming it yet. In the confirmation box, the file extension will appear. If you’ve downloaded the file, you can still check it by going to the download location and noting the extension. Be sure the format matches the extension of the file you want to download.

There are a handful of common file types that get used frequently:

• PDF: A .pdf file extension is a Portable Document Format created by Adobe that gives you an easy way to exchange files, no matter what system or software you use.
• PPT: Microsoft PowerPoint presentation extensions are used for presenting various files such as images, graphs, and animations in one slideshow.
• TXT: This extension is used for files that contain text and no other objects, such as graphs or tables.
• DOC and DOCX: These are some of the most used file extensions. They are native to Microsoft Word and can contain text, images, graphics, and tables.
• MP3: This file extension is the most popular for audio files and is saved in a compressed format.
• MP4: This extension is used for video clips and movies. It’s used for streaming videos on the internet and is compatible with many devices.
• JPG and JPEG, GIF, and PNG: These extensions are standard file formats for images. They are compatible with every operating system and are widely used on the internet.
• EXE: The executable extension is primarily used to install or run programs on Windows computers.

Are .zip files safe to download?

Zip files are safe to download in most cases. But you should be cautious when you import a .zip file from an unknown source because it can contain malware.

To be safe, it’s best to scan all zipped files with your antivirus program before you extract them. Using an antivirus is important to help keep all your devices secure.

Scan the download link with VirusTotal

When you’re not sure if the link you want to download is safe, you can use an online virus scan tool like VirusTotal that checks the link. These tools are web-based antivirus scanners that check a URL, file, or IP address for potential threats.

It usually only takes a few minutes to complete the entire process. You go to the site and find your document type, then click a button to upload your file. After that, you’ll get the results that let you know whether the file could be compromised.

Scan downloads for viruses

It’s always a good idea to use a trusted antivirus program to check for viruses before downloading any files to your device.

There may be different ways to scan a download depending on your antivirus software, but there are general steps you can follow to scan files for viruses:

1. Once you download the file, right-click on it and choose the option to scan with your antivirus software.
2. You can also scan multiple files by holding down the Ctrl key and clicking on each file you want to scan, then choosing the option to scan with the antivirus software.
3. If your antivirus program flags the file as malware, you can quarantine it or completely delete it.
4. After you delete or quarantine your file, you should restart your device and run a second virus scan to be sure the malware is completely gone.

Use an antivirus with web browser protection

Many antivirus programs, such as AVG, actively block malicious files from being downloaded while you browse the internet.

Some web pages can even sneak into the Google search results and pose as legitimate sites, then download adware, spyware, Trojans, or other malware onto your device when you click the link.

Check the number of downloads

Some websites will display the number of file downloads on their site. If you see that a file has been downloaded numerous times, it could indicate that the file is safe.

You should still be cautious because this doesn’t always mean a file is safe. A large number of file downloads could still mean that the people who already downloaded it received some kind of malware.

In the end, a large number of downloads simply means that other people trusted the files, not that you should deem them trustworthy. Use your best judgment, as well as our other tips to help.

Check download reviews and forums

There are download forums online that will post user reviews to let you know about their experience with a download. You can search online for these reviews to see what other users have reported.

You can also look at the number of stars a download is rated to see how much users liked it, but what you mainly want to look for are comments about any malware or virus issues. Reviewers often freely let you know if they had any trouble with a download.
