Software updates are necessary when companies identify application errors or weaknesses in their software or system that require stronger security protections.
About software updates
Software updates come in the form of software “patches” that replace defective sections of software code with corrected code. All software manufacturers issue patches either on a regular schedule or as defects are discovered. Malware such as viruses, worms and trojans can infiltrate a computer through a software application that has not been patched.
Automatic updates are included in most operating systems and software programs. These features periodically and automatically update your computer.
- Microsoft Windows calls this feature “Auto Update.”
- Mac OS calls this feature “Software Update.”
- Other software programs may display pop-up notices within a program notifying you to install the latest software patches.
