A malware scanner online is a tool that scans your computer or mobile device for viruses, spyware, and other cyber threats. This can help prevent data breaches, loss of information, and even system failures. These tools typically offer clear guidance and one-click fixes if they identify a security threat, and many also come with features like vaults to store files and images in secure locations or make them unaccessible to unauthorized users.

Some online virus scanners, such as VirusTotal, require no download and are incredibly simple to use. This tool simply analyzes the information that your computer automatically sends to websites as you browse and scans individual files. This makes it a great choice if you are unsure about a specific file and want to cross-reference it against a database of known threats. Other online security tools, such as the SafetyDetectives Known Vulnerabilities Scanner and Trend Micro HouseCall, are more complex and offer customizable scanning options.

Some online tools focus on scanning the front-end pages of a website, such as IsItWP. This is often much quicker than a full-scale web vulnerability scan, but it won’t pick up issues that are hidden behind the scenes. In addition, IsItWP does not provide any guidance or tools to remove any discovered malware from a site. In contrast, other tools such as SiteLock’s free scanner can check both the public-facing pages and the back end of a website, allowing you to spot problems that other free scans might miss.
