Malware is back with a bang in 2022. In fact, major cybersecurity companies like Trend Micro and Barracuda are already predicting that ransomware will be one of the top security issues for 2022 and the foreseeable future. Therefore, ensuring that what you or your employees are downloading from the internet is malware free has become paramount.

But how can you do that without spending days browsing the web for the perfect tool? There are so many options out there that picking a good, reliable and safe download checker tool that can get the job done without spending a fortune can become a daunting task! That’s where this article comes in. Here, you’ll find:

  • A list of the best safe download checker tools.
  • A comparison table that shows the key features at a glance.
  • A few extra tips to ensure a safe download.

Protect Your Devices from Malware: Check All Apps Before Downloading Them

Whether for personal use or for business, virtually everyone downloads software, files, apps from the internet. These activities can occur once every few days or potentially even several times a day. It’s normal, convenient and, very often, it’s free.

But downloading stuff from the internet isn’t always all sunshine and rainbows: viruses and malware are lurking everywhere like mousetraps, just waiting for the next victim to click on the bait and get infected. This is why many companies create policies regarding computer use that outline which activities are (or aren’t) permissible on company-issued devices. These types of policies can help mitigate shadow IT concerns — but they only work when people adhere to them.

What’s Malware and Why Is It So Dangerous?

Malware, short for malicious software, is any program or file developed by cybercriminals to steal data and damage your device’s operating system. The most common malware are:

  • Viruses,
  • Worms,
  • Trojans,
  • Spyware,
  • Adware, and
  • Ransomware.
Malware wreaked havoc in 2021 and shows no signs of slowing down this year. Considering that global consumers download more than 435,000 apps per minute, the opportunities for attackers to inject malware into an application’s code and infect those who download it are countless. And these numbers are just app figures; they don’t even count other kinds of downloads (e.g., executables, software programs, videos, documents — you name it).

What can you do then? How can you protect your devices and organization from potentially harmful downloads? Last year, we gave you some tips on how to check if a file has a virus before downloading it; this year, we’re going a step further. Follow us into the rabbit hole and discover the best safe download checker tools to keep you safe in the wild.
