If you suspect that your device is infected with a virus and you haven’t yet installed a paid antivirus, then a free online virus scanner can provide a quick and easy solution without having to download and install any software.

What is a Virus Scanner?Ī virus scanner is a web service that scans your device from a remote server. While an online virus scanner can not replace your antivirus which runs offline continually in the background, it can be helpful for quickly identifying infections. Most require you to download software in order to work. Many antivirus services claim to offer free online scanning tools, but very few are actually cloud-based services.
