Normally, the host program keeps functioning after it is infected by the virus. However, some viruses overwrite other programs with copies of themselves, which destroys the host program altogether. Viruses spread when the software or document they are attached to is transferred from one computer to another using the network, a disk, file sharing, or infected email attachments.

If a file isn’t from a known source, Chrome sends the URL and IP of the host and other meta data, such as the file’s hash and binary size, to Google. The file is automatically classified using machine learning analysis and the reputation and trustworthiness of files previously seen from the same publisher and website. Google then sends the results back to Chrome, which warns you if you’re at risk.
