About Pulse Updates
In addition to the definition updates that Automatic
LiveUpdate downloads, Norton 360 uses streaming
technology to download the latest virus definitions.
These downloads are called Pulse Updates. The Pulse
Updates are lighter and faster than Automatic
LiveUpdate. They keep your computer secure from the
ongoing threats that exist on the Internet. Pulse
Updates protect you against the rapidly-changing
environment of security threats without compromising
your computer's performance. Pulse Updates should
always be turned on to get the latest updates.
Pulse Updates checks for definition updates every 5
minutes. If definition updates are available, LiveUpdate
downloads the streamed virus definitions. Pulse
Updates provide the updates in between the full
updates, which Automatic LiveUpdate downloads
automatically every hour. Norton 360 merges the new
stream that is downloaded with the last updates that
are installed. The Pulse Updates downloads provide
additional and fast protection for the latest threats in
between the full updates without disrupting your online
experience.
