There sure is.

One of many that is widely accepted is AVG. And it is free.

However you want to run the Norton removal tool first to uninstall Norton.

When you install AVG just accept it's defaults.

For variety, as well as AVG, there is another highly regarded av program which is free:

You can also pay for av software which is lighter and less expensive than Norton:

Good luck!!!
Sorry.  That second link should be:
