A Free Online Virus Scanners is an online-based, free scan for viruses and malware. This kind of virus scan differs from your traditional virus scanning program because all the work is done on a server on the internet.

Free online virus scanners are good options for one-off virus scans if installing a full-fledged antivirus program isn't an option for some reason, or maybe just for an extra layer of precaution.



 Free online virus scan services listed below are completely free.

Avira




Avira's online virus scanner uses the same antivirus engine as the popular Avira AntiVirus program to scan submitted files and URLs through an online form.

 The form asks for your contact details so the URL of the results can be sent to you. A maximum of five files no larger than 50 MB each can be uploaded.

Kaspersky VirusDesk




Kaspersky has an online virus scanner, too, that supports both files and URLs. A file you upload to this online virus scanner can be as large as 50 MB.

 The website couldn't be easier to use. Just paste the link or select the attachment icon to upload a file. Pressing SCAN starts the virus scan and the results are shown on the same page.

 If a threat is detected, Kaspersky VirusDesk will say "Threats detected in " and show the threat name and other details. Otherwise, you'll see a clean, "No threats detected" message.

MetaDefender Cloud





MetaDefender Cloud (previously called Metascan Online) is a slick website that allows files up to 140 MB to be uploaded and scanned against 30+ different antivirus engines at once, including ones used by popular vendors like Microsoft, Kaspersky, McAfee, and AVG.

 A few files you might be interested in scanning at MetaDefender Cloud could be 7Z, EXE, and ZIP, but you can scan others, too, like images, videos, and documents.

 In addition to uploading a file to MetaDefender Cloud, it can also scan by IP address, hash value, and website URL.

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

 There's also the OPSWAT File Security for Chrome extension you can install to scan downloads made through that browser.
