Every computer needs protection, and while most PCs already have antivirus software installed, sometimes you need an extra layer of security. That’s where free online antivirus tools come in handy. These scanners let you detect and remove malware, spyware, and viruses without installing a full antivirus suite.
It’s important to note that online antivirus scanners are not a replacement for full antivirus software they don’t provide real-time protection. Instead, they are best for one-time scans when you suspect your system might be infected.
Below is a list of the most reliable free online antivirus tools you can use to scan files, URLs, or your entire system.
1. ESET Online Scanner
ESET Online Scanner is one of the best free online antiviruses we’ve come across, with a user interface that’s both straightforward and simple to use. This online programme allows us to choose whether we want to scan or examine our computer. It also allows us to specify whether we wish to quarantine or delete any suspicious files that have been found.
2. MetaDefender
MetaDefender is a free online antivirus programme that scans files for viruses and spyware. It also gives us the option of scanning a file, an IP address, a domain, a URL, or a CVE. Furthermore, it includes an easy-to-use interface that allows us to quickly access all of the available analysis choices.
3. Panda Cloud Cleaner
In the security industry, Panda Security is a household name. Panda Cloud Cleaner is a free internet antivirus programme offered by the company. Use a web-based tool to eliminate all unneeded processes before performing a further investigation to uncover any malicious files that may be hiding behind other running processes. To use Panda Cloud Cleaner, simply select the harmful files and click on the delete button after the analysis is complete.
4. Google Chrome Antivirus
Although many users are likely aware, others may be unaware that the tech giant Google’s well-known and most widely used web browser, Chrome, includes an integrated antivirus function. To utilise it, type “chrome:/settings/cleanup” into the Chrome address bar and click Enter. After that, we’ll be taken to a screen where all we have to do is click the Search button, and the procedure will begin on its own.
5. F-Secure Online Scanner
It’s also worth taking a look at F-Secure Internet Scanner, which is a free online antivirus. Also, it’s one of the most responsive online anti-viruses we’ve come across. It is, however, one of the most fundamental. It doesn’t provide us the option of making a comprehensive, simple, or personalised scanner using it.
F-Secure Online Scanner, on the other hand, excels in scanning quickly. As a result, we won’t have to wait as long before using this free online antivirus again. However, due to the lack of features, it is a simple tool to use.
6. VirusTotal
You can scan a specific file with another free internet antivirus. You can rapidly determine whether the file type you are about to download is safe or not with Virustotal. VirusTotal allows us to analyse files up to 256MB in size, and we can also submit our email address to receive a complete report.
7. Comodo Free Online Scanner
Comodo’s Free Online Scanner is a well-known and very powerful antivirus scanning application available on the Internet. Furthermore, the well-known Comodo Free Online Scanner immediately activates and begins scanning.
8. VirScan
As an alternative to the previous ones, VirScan is a free online antivirus that lets you scan only a single file up to a maximum size of 20 megabytes (MB). The only way to scan multiple files at once is to compress them all into a ZIP or RAR file and then scan it.
9. BullGuard
BullGuard Virus Scanner is a programme that has to be installed. It quickly goes to work after installation and detects any suspicious files or activities. Not only that, but after the scanning is completed, the scanning report can be read as well.
10. Kaspersky Threat Intelligence
Kaspersky Threat Intelligence, on the other hand, is an online virus scanner that analyses files and web URLs. It’s a free web tool that detects risks using Kaspersky’s threat intelligence database. The online scanner is quite good at finding risks concealed in URLs, downloads, and other places.
