NoAdware software is often updated. First of all updates are simple new "protection" against spyware, adware and more...

So it is recommended you set automatic option switched on so that your computer is also protected against the NEW dangerous objects not just those that already exist. That's very important.

Automatic updates doesn't take lots of time to complete. You will see a message when it starts and if you don't do anything else until updates are downloaded everything will take much less time and run very smooth. (Don't play games or open other programs while downloaded)

Updates occur either weekly or sometimes daily so check often if you do it manually. Automatic updates are instantly downloaded. Less work on your part...
