When I put my Webroot antivirus on my computer it is saying expired.

Hello @.
 
Welcome to the Webroot Community,
 
Would you please uninstall and do a clean reinstall of Webroot and see if this clears up your connecting issue.
 
Please follow the steps closely!
 

• Make sure you have a copy of your 20 Character Alphanumeric Keycode! Example: SA69-AAAA-A783-DE78-XXXX
• KEEP the computer online for Uninstall and Reinstall to make sure it works correctly
• Download a Copy Here (Best Buy Subscription PC users click HERE)
• Uninstall WSA and Reboot
• Install with the new installer, enter your Keycode and don't import any settings if asked to as you can set it up as you like once it's done
• Let it finish it's install scan
• Reboot once again.

Please take a look at this guide describing how to activate your new keycode
