Seti Astro Suite Pro - Windows11 with Norton 360

Georg N. Nyman · Sep 18, 2025, 02:59 PM

A question for you all - in case you have already downloaded and installed the new Seti Astro Suite Pro!

My workstation is running with Windows 11 and Norton 360 - downloading the Suite did only work after I had stopped Norton 360 protection. I was then able to install the suite and run it - as long as Norton 360 was disabled. But I need to have Norton active as you can imagine - however as soon as I enable Norton 360, the suite is automatically closed and locked away - Norton tells me, it is a dangerour malware.

What I can I do? Any advise available?

Thanks and CS

I’m not a Norton 360 user, AVG Internet Security subscriber here, but there should be an exceptions list you can add Seti Astro Suite to so that the anti-virus software doesn’t move the software to quarantine.

Per Norton 360:

“Add exclusions for your Norton scan

1. Open your Norton device security product.

2. On the left pane, click Security.

3. In the Security dashboard, in the Scans tile, click Open.

4. In the Scans window, click the Exclusions tab.

5. Click Add/Add Exclusion.

6. In the Add Exclusion window, click the browse icon.

7. Navigate and select the file or folder that you want to exclude from Norton scans, and then click OK.

8. Click Add.

   The item is added to the Exclusions list.

To exclude a file from Download Intelligence, you must download the file to an excluded folder. You can add a folder to the Exclusions list and then download the file to that folder.”

Hope this helps!

I use AVG and had Set Astro listed as an exception, and still couldn’t use Seti Astro when AVG is turned on, if it even opens at all, so had to give up and delete seti Astro, I also sent a message to Frank about it, but he was not at all really interested, which was a shame ☹️

That’s a shame, sorry to hear that.

Mikołaj Wadowski:
For 99% of users third party AV software is completely pointless. If it gives you any issues, uninstall it. Windows defender is sufficient nowadays.

Edit: + given Norton’s past, I’d say that, ironically, it itself is more of the malware it’s trying to protect you from

No, that’s not a shame. You cannot expect a developer to test his sofware with all available AV softwaree on the market.

And, as expressed already by others, any other AV software than MS Defender is pointless. Especially Norton…

AV Software should not be installed at all on the observatory PC. Protection on network level is the key to security.

I’m sorry, I don’t understand the tone taken here. Expressing empathy at someone’s situation doesn’t equate to the level of response taken in this message.

That said, sure, you can use Windows Defender—I’m not advocating for any software to be used over an other.

You're right, my tone was sharper than it needed to be, and I apologize for that. I reacted strongly because I thought the word 'shame' implied blame on the developer, and I wanted to defend them. I see now you were just being empathetic. My point about AV software was a separate rant that I shouldn't have bundled into my response.

Hi George,

I use SAS Pro, Windows 11, and Norton.

1. Open Norton.

2. Click the Security tab.

3. In the new window click on Quarantine.

4. You should see the Seti Astro Suite file in quarantine.

5. Look for the option to edit. (Maybe 3 dots to the right). Look for the Restore option. This will move the file back to it’s correct location.

6. For the first startup Windows Defender will complain. Choose to run anyway and you’ll be good to go.

This is what I have to do with every update Frank does. Takes under a minute and is no issue at all.

Please reply if you are still having issues and I will delete SAS Pro and reinstall so that I can do screen captures for you.
