Abstract

Detecting viruses that may be transferred between a distributed computer network, such as the Internet, and a host computer. A host computer performs its own virus scanning on data, using executables code downloaded to its browser upon a request for data from the Internet, such as an HTTP request. Code is downloaded to the host computer, and is configured to create a virus scan module on the host computer upon such a request. The module is used to detect viruses in data transferred between the host computer and the Internet. Virus scanning is performed thereafter on the host computer. In cases where certain browsers may not be capable of supporting local virus scanning, code is first downloaded to determine whether local scanning is possible. If so, the virus scan module is then downloaded and executed.
