antivirus - How do I avoid su-ing to root

I need to install Symantec Antivirus for Linux on my computer.

According to its README file, it says:

Debian and Ubuntu users should use sudo

For installation and when you execute Symantec AntiVirus for Linux commands, Debian and Ubuntu users should use sudo. Do NOT su to root for these actions. In addition, ensure that the user who is running the command is in the sudoers list.

Question #1: How do I avoid su-ing to root?

I'm new to Linux and Ubuntu.

During the installation process, I entered the following details:

Name: Sharon

Account name: Sharon

I notice that whenever I open up a terminal window, it says:

sharon@sharon:~$

Question #2: Is sharon@sharon:~$ root?

PS: I am very new to Linux and Ubuntu; please excuse me if my questions seem elementary.

1) What do you mean by that? sudo gains the account a temporary root privileges. Some applications will need these privileges and you will need to sudo. If however you don't want to type sudo all the time, then type sudo su BUT THAT'S NOT RECOMMENDED.

2) No.
