When software updates become available, vendors usually put them on their websites for users to download. Install updates as soon as possible to protect your computer, phone, or other digital device against attackers who would take advantage of system vulnerabilities. Attackers may target vulnerabilities for months or even years after updates are available. Some software (like Total Defense Ultimate) will automatically check for updates, and many vendors offer users the option to receive updates automatically. If automatic options are available, you should take advantage of them. If they are not available, periodically check your vendor’s websites for updates. Make sure that you only download software updates from trusted vendor websites. Do not trust a link in an email message.
