When does Norton automatically detect and resolve threats?

I recently-ish received a sketchy looking email that contained a file that ended with ".pdf.zip". I removed it, obviously. Half an hour or so ago Norton came with a popup while my PC was idle, saying a security threat had been resolved. Apparently it was of a malicious .js file located in my main email account's trash folder. Now, obviously it's all fine since Norton got rid of the threat, and all scans I did (regular scan, Power Eraser, Malwarebytes Anti-Malware) came out clean. I also haven't noticed anything weird.

It's not so much about said file though, it's more about when Norton decides to look for and respond to threats. What exactly determines Norton's response? What are the conditions that have to be met? As far as I know whenever a malicious file is moved or copied, Norton will take action, ignoring .zip files. Does it only detect a threat once it shows activity of some kind? Or does it remove it when it happens to bump into it by accident, regardless of it showing activity or not?

I don't really recall since it seems to vary a lot per file type. Can anyone clarify on this? I'm just really curious about how and when Norton Security detects threats, and decides to take action. I can't really find any detailed information about this.

If you had just brought the machine out of idle Norton will tell you then as it knows you're at your machine.  If you check your Security History you would probably find the detection was earlier.

A little bit of knowledge is... well a little bit of knowledge.

Sometimes hard to do just one.

Re: When does Norton automatically detect and resolve threats?

Makes sense. So I'm guessing "Background tasks" also include scans and checkups of files on the system to make sure there's nothing nasty? That would explain why my other hard drives keep waking up whenever my PC goes idle and Norton takes over.

It's an informative page, but it really doesn't describe anything I didn't know yet. I'm just guessing Norton's idle tasks are the same as the ones the user can perform manually, except it runs them, well, in the background, obviously.

Re: When does Norton automatically detect and resolve threats?

Norton runs a Quick Scan after every definitions update, so that would generally be 2-3 times a day, if your PC is always on.  This looks for active threats - items that are running or are capable of running.  A file lying dormant that would only run if you launched it manually would probably not be detected by the Quick Scan, but would instantly be detected by Auto-Protect as soon as the file was accessed by you or a process running on your computer.  A full system scan would likely alert to the file, but running a full system scan frequently is not really something you need to do.

Note that moving a file to the trash folder does not remove it from your computer (it actually creates a copy on the file in the Trash folder and only hides the original), and with some clients, like Thunderbird, even deleting a file from the trash does not physically remove the file - to do that, you also need to compact the folders.  So we sometimes do see cases, especially in Thunderbird, where malware is detected even after a file has been "deleted" from the Trash folder.

I did not know Thunderbird was so sloppy. Apparently I had loads of junk lying around. No wonder. I wish Thunderbird was a bit more serious about security because other than that it's the best email client I've used so far. It's all gone now though. I guess that's something to keep in mind in the future.
