How To Change Antivirus Programs

Dear Computer Lady,

Okay, my Norton license is going to expire in 30 days and I want to install the AVG and the other two software packages you recommend.

Should I remove the Norton first or would it be safe to install the AVG and then the two other applications…

In other words “What order do you recommend?

Thank you very much, Patty


Dear Patty,

You never want to install a new antivirus program until after you have removed your old antivirus program. Here is what I would suggest you do.

First, go to my website at and click on the button on the left that says, “More Questions”.

On the question and answer page, there is a list of programs that I use and recommend on the right hand side. Click on the link for AVG. This is my affiliate link, I earn a small percentage of the purchase price, and there are often special deals offered to you through my link.

The AVG page will have a place where you can download a 30 day trial of the program. Follow the prompts to download the file and save it on your computer. Don’t run the file at this time, just save it and remember where you have saved it.

Once you have downloaded the AVG file, go to the control panel, click on “Uninstall a Program” find the Norton program. Click on it, then click the “Uninstall” button at the top of the page.

Once you have finished uninstalling Norton, restart your computer.

When your computer starts back up, go to the AVG file you downloaded earlier and double click on it to install AVG.

Once you have AVG installed, you can install the two anti-spyware programs that I like to use. They are not antivirus programs, so you are safe to have them installed on your computer along with AVG.

    Dear Computer Lady

    In my opinion, I think your response to this question is incomplete. Your procedure for removing Norton will leave a plethora of Norton scraps all over Patty’s hard drive. May I suggest that she use a dedicated uninstaller program, e.g., Revo Uninstaller (I am merely a user of the free version, with no other connection to Revco). My experience with uninstalling Norton requires some diligent searching to remove each piece of it.
