Online antiviruses are interesting tools for a quick computer scan and protection against dangerous files. In addition to doing a complete system scan for free, they also offer analysis and removal of infected files. However, it is important to note that online antivirus does not replace the protection software already installed on the computer.
These tools are useful for scanning, but they do not provide real-time protection like offline software and, therefore, you should not entrust the system security to them alone. In the list below, find out the best seven online antivirus options to use on your PC, four of which are for full scanning and three for scanning suspicious files.

Chrome users can scan the system directly from the browser. To use Chrome’s free antivirus, you need to open your browser and paste the following command into the address bar: chrome: // settings / cleanup . When the page loads, the user must click «Search» and let Chrome scan the computer for infected or suspicious software. This antivirus has only one standard scanning option, but it does not take long. The great advantage of this option is that you don’t need to install anything other than the browser. It is important to remember, however, that the tool does not work in other browsers.

4. F-Secure Online Scanner
The F-Secure Online Scanner is another one on the list that does not need installation, although it is necessary to download the application to run it on the computer. It does a quick scan of itself, but it takes a while to start the process, because it needs to do a scan first. The interface is clean and easy to handle, which makes this online antivirus a good option for those looking for a simple scan. At the end of the analysis, the program presents the infections found and allows the user to permanently delete the malicious files.

Unlike the previous options, VirScan – like the next two on this list – is an individual file checker. This means that, instead of scanning the system, it scans only a file selected by the user. This option is useful for those who want to make sure that a downloaded file is safe before opening it, for example. VirScan features a database of malicious files. It allows the user to upload a file of up to 20 MB to be verified. The file is analyzed based on a comparison with this database and the tool indicates whether it is safe to keep it on the computer.

Another file scanner, Virus Total also allows you to search a database. However, it has an advantage over VirScan: it allows not only the user to upload a file, but also to verify a URL or IP address. Another benefit of VirusTotal is that it offers the analysis of larger files through an email consultation. The user sends the suspicious file directly to VirusTotal’s email and the company responds with the analysis of the material. In this format, it is possible to check files up to 256 MB.

Useful in checking files, MetaDefender takes information from more than 30 antivirus to analyze a document sent by the user. In addition to a file, you can verify a domain, URL, or IP address. The site receives files of up to 140 MB to be analyzed and the user must upload them on the platform. After checking the content, the tool presents its vulnerability score and offers the option to download the «sanitized file». Metadefender has a pleasant and elegant design and is easy to handle.
