Keeping virus definitions up-to-date

Your virus signature definition files are automatically updated regularly.

What are virus signature definitions?

Every virus or spyware application contains unique identification information, known as its signature definition file. Security software uses these files to detect viruses and spyware on your computer.

As new viruses or spyware applications are discovered, your security software updates its databases with the signature files it needs to detect these new threats.

Therefore, your computer is vulnerable to viruses and spyware whenever its database of virus signature definitions files becomes outdated. But, don't worry, because:

• By default, your virus definition files are automatically updated regularly.
• If you hear of an outbreak and want to get the latest updates immediately, select Update in the main window.

To customize automatic signature updates:

1. From the Tools menu, select Schedule Tasks.
2. Next to Anti-virus Update choose an option from the Frequency menu.
3. Click Apply.
