Nord Security, maker of the popular VPN service NordVPN, has published a new online tool. File Checker is a free online security tool to check files for malware.
Online virus scanners are useful to check a small number of files for viruses and other unwanted code. Google-owned Virustotal is probably the uncrowned king of these types of tools.
Here is what you need to know about the new File Checker tool:
- It is free to use on the NordVPN website; an account is not required.
- File Checker works on any platform.
- Recommended file size is 50 megabytes or less, but it works with larger files. There is a limit though, as it would not scan a 160 megabytes file.
File Checker is also integrated into NordVPN’s Threat Protection feature. I did not give the feature a recommendation back then as it installed a certificate on the system that gave it a high level of control.
Threat Protection back then supported the scanning of files, but limited this to files of a size of up to 20 megabytes.
File Checker
The website provides little information on the File Checker technology. Most of the information is basic, explaining that you can get viruses through infected phishing emails or that PDF files can contain viruses.
In fact, the only information about File Checker is that it was created by NordVPN.
File Checker was developed by NordVPN, a global leader in cybersecurity with over 10 years of experience. Our experts curate a massive real-time database of threats and use advanced technologies, including artificial intelligence and machine learning, to continuously improve File Checker.
Nord Security maintains a list of threats and uses technology, including AI and machine learning, to improve it. This does not tell us anything about how good or bad the product is.
File Checker does have a few disadvantages when compared to Virustotal:
- You can only scan individual files that are on the local device already and links. Virustotal supports this and it includes a Search for finding already scanned files.
- Virustotal furthermore displays information about the scanned file, including details, behavioral information, and also community comments.
- File Checker uses a single service, Nord Security’s own, to scan files for malware. Virustotal checks dozens of antivirus engines, which provides a clearer picture.
Should you use the standalone File Checker tool?
While it is commendable that File Checker is free, it is held back by the fact that it relies on a single threat database. Virustotal is the better option, as it provides results from dozens of antivirus services.
Furthermore, it is integrated in NordVPN, which means that all customers may enable this to get automatic file checking. Still, most antivirus applications support this as well.
What about you? Do you use online file scanning services to check downloaded files before you open them on your devices?
