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.

Archives like ZIP and RAR can be uploaded but the maximum acceptable size for any file type is 128 MB.

Metadefender (previously called Metascan Online) is a slick website that allows files up to 140 MB to be uploaded and scanned against 43 different antivirus engines at once, including ones used by popular vendors like Microsoft, Kaspersky, McAfee, and AVG.
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.

The form asks for your contact details so the URL of the results can be sent to you. A maximum of 5 files no larger than 50 MB each can be uploaded.
Over 20 antivirus engines are used to scan up to 5 files at a time (with a 50 MB limit for each) that you upload to Jotti’s Malware Scan.
The date and scan detection status of each antivirus engine is shown in an easy to read list so you can clearly see which ones did or didn’t find the file to be dangerous.
Jotti.org also includes a hash search if you wish not to upload a file but instead enter the MD5 or SHA-1 cryptographic hash function of a file. This will only work if the file was scanned by Jotti.org at an earlier date, by you or someone else.
