Online antiviruses are interesting tools for fast computer scanning and protection against dangerous files. In addition to a full 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 protection software already installed on the computer.
These tools are useful for scanning, but do not provide real-time protection like offline software, so you should not rely on system security alone. In the list below, you will find the best seven online antivirus options to use on your PC, four of them full scan and three scan for suspicious files.

Google Chrome users can do a system scan directly from the browser. To use Chrome's free antivirus, I need to open the browser and paste the following command into the address bar: chrome: // settings / cleanup . When the page loads, the user should click "Search" and let Chrome scan the computer for infected or suspicious software. This antivirus has only a standard scanning option, but it doesn't take long. The great advantage of this option is not having 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
F-Secure Online Scanner is another one on the list that needs no installation, although you need to download the application to run it on your computer. It does a quick scan itself, but it takes a while to start the process because it needs to do a scan first. The clean interface is easy to handle, making this online antivirus a good choice for those looking for simple scanning. At the end of the scan, the program displays the infections found and enables the user to permanently delete malicious files.

Unlike previous options, VirScan like the next two in this list is an individual file checker. This means that instead of scanning the system, it scans only one file selected by the user. This option is useful for those who want to make sure a downloaded file is safe before opening it, for example. VirScan presents a database of malicious files. It allows the user to upload a file of up to 20 MB to be scanned. The file is analyzed based on a comparison with this database and the tool indicates if 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 not only allows the user to upload a file, but also to verify a URL or IP address. Another benefit of VirusTotal is that it offers analysis of larger files through an email query. The user sends the suspicious file direct to VirusTotal's email and the company responds with material analysis. In this format, files up to 256 MB can be scanned.

Useful for scanning 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, a URL, or an IP address. The site receives files of up to 140 MB to be analyzed and the user must upload to the platform. After checking the content, the tool displays its vulnerability score and offers the option to download the "sanitized file". Metadefender has a nice and elegant design and easy handling.
