Antivirus software is a program that is designed to find and neutralize malware and viruses. These programs are able to scan your computer’s hard drive and identify files that are malicious or suspicious. The antivirus software can attempt to delete, quarantine, or trigger an alert when it detects files that are harmful. Additionally, many antivirus software suites also have settings that can prevent your computer from downloading or executing harmful files in the first place.

I was able to upload 7Z, EXE, ZIP, and a few other similar file types to Metadefender, as well as other common files like images and documents.

In addition to uploading a file to Metadefender, it can also scan by IP address, hash value, and website URL, as well as scan using an app. Some of the apps include a Chrome extension that scans all downloads, an Android scanner, and one for Windows and Mac that checks any folder for malware.

Results are really easy to read; a bright green check mark is placed next to each antivirus engine that identifies a file as safe and a red mark with the virus name if found to be malicious.

This will only work if the file was scanned by at an earlier date, by you or someone else.
