As vulnerabilities are discovered, the vendors of the operating systems or applications often respond by releasing a patch. A patch is designed to correct a known bug or fix a known vulnerability, such as in this case to be vulnerable to virus infections, in a piece of software.
A patch differs from an update, which, in addition to fixing a known bug or vulnerability, adds one or more features to the software being updated.
