Have you tried right-clicking the "Start" button and going into "Apps and Features" to uninstall it/them?

Myself, one of the first things I did was uninstall Norton (if I remember correctly).

That let Windows security take over which was enough for me, but may or may not be for you.

If it's not, there's Avast Free or... truthfully, I don't know what's best now. I generally use Linux.

Norton has an uninstall tool on their website to get every last bit. Mary

https://support.norton.com/sp/en/us/home/current/solutions/v60392881

When I followed Richard's suggestion I found no mention of either of these products. So then, Mary, I followed your link and found instructions for uninstalling the programs--but again, neither of these programs showed up.

I have two operating systems on this computer; I wonder if Norton, etc., is on Win7. I wouldn't think so, because I ran only Win7 for years with not even a hint that Norton was on the computer. But I'll turn the computer off tonight and switch over to Win7 tomorrow morning and I'll report back on what I find. Thanks very much!

The Norton tool usually work a to get every last bit of their program. If they came with the computer when you bought it they should still uninstall. Hopefully someone here can help. Did you look in uninstall programs on windows 7 to see if they were in the list? Mary

If you've ran Win7 on the computer for years, I wouldn't think you'd have Norton on Win10 without knowing about it. Did you or someone else install Win10 alongside Win7? Recently?

It's strikes me as strange that both Norton and McAfee are suddenly both claiming to be expired at the same time.

Normally, I don't think you (or anyone else) would have even installed both because they can conflict with each other.

Suspicious thought but maybe it's some sort of malware pretending to be AV and wanting you to whip out your credit card and pay to renew a product you don't even have. They wouldn't know that so might mention both AVs. (To cast a wider net?)

Have you scanned with Malwarebytes? (I think there's still a free version but it starts out as a 14 day trial of premium?)

Next time you get the notification, can you post a screenshot?

Richard, I'm afraid I like your suspicious thought. In addition to telling me the programs had expired and needed to be renewed, the notices sometimes tell me my computer is infected, or someone is tracking me, or other threatening stuff, which I thought was odd. They don't say it might be infected; they say it is. That seemed less than ethical to me. I'll give Malwarebytes a shot. Thanks!

Let us know. I don't run Windows much and am not a tech so I don't keep up with what are the latest most effective malware removal tools.

But I think there are users here who do.

Malwarebytes always used to be good though, so I suspect it still is.

I started up the computer this morning but couldn't make the switch to Win7. The usual procedure is for me to press the Esc key, which gives me the Startup Menu option. Then I press F9 and then choose the SATA version I want. This morning when I pressed the Esc key all I got was an option to press F1 to boot. I waited, but nothing happened. Tried this twice, and finally pressed F1 to start the computer in Win10. That never happened before.

Malwarebytes detected no threats.

Here's a screenshot. Usually the popups arrive 4 to 6 at a time, stacked so that two are visible at any time. They don't normally disappear until I click on their arrows, but this morning these two went away on their own.

At first glance that looked legit but... (and if it was, McAfee would have been in your list of installed programs)

That's not coming from the Windows notification area is it?

I may be wrong but it looks like it's within the browser. (Could just be how it's cropped?)

Do you get the notifications only when your browser is open?

If so, only when it's open to (a) specific site/s?

What browser are you using?

Have you tried a different one (such as Firefox or Chrome) and if so, do you get the same notifications in it?

BTW, I've never run different versions of Windows side by side like you. I do Linux and Windows side by side and I'm fine letting Linux handle the boot menu but... Windows boot files are a mystery to me. :)

The only thing I cropped off was the very top edge (so you wouldn't tell me--as my son does--that I have too many tabs open lol). I'm using Chrome, and yes I get the notifications only when my browser is open--which is all the time, since I use two monitors and any other task is done on the other monitor. The site doesn't matter, as the notifications don't discriminate.

I have Firefox, but rarely use it. I'll give it a try, thanks!

If you only get the notifications when Chrome is open but never get them when Firefox is open, there's probably an easy way to reset Chrome. Maybe a toolbar is causing the notifications?

Hopefully it is just a toolbar or some browser extension. Good luck.

Oh, great. Firefox won't load anything, and now neither will Chrome. That is, Chrome won't go to any new sites and won't open some of my tabs. However, it will refresh some pages--which is how I'm able to post this.

What I'd probably do...

Restart Win10 and see if that helps.

If it did not, I might boot into Win7 and see if everything is okay in there.

If Win7 was okay, I'd try Win10 again.

If Win10 was still misbehaving, personally, and this is just me, I'd be feeling frustrated and feel a need to walk away for awhile. (Away from Win10 at least, I might boot back into Win7 and use that for awhile)

Maybe it's just coincidentally an Internet problem? (But since you were able to post, maybe not?)

Another thing I might try, especially if I didn't use Firefox very much and didn't care about losing add-ons is do a refresh to see if that helped. (Help->Troubleshooting Information->Refresh Firefox)

This may or may not help but...

If nothing else, it does seem to confirm it's a scam.

When my kids were little I used to read the medical advice of Dr. Robert Mendelsohn. He said if a symptom develops and you're not sure what's going on, think back to what you were doing just before it started. What change did you make that might have caused this?

Of course, this advice applies to other things as well--not just physical health. So I looked a few minutes back and realized the problem loading pages started after I installed Malwarebytes. So I uninstalled it. And now the pages load perfectly.

Here's a screenshot of the latest popup. I assume it's not something I should take seriously, but please tell me if I'm wrong. It has the same solo3.biz that I see on the Norton/McAfee notifications.

Yeah, definitely looks to originate from "within" the browser. I can't tell if it's just an ad or a "push notification" though.

Out of curiosity, I booted Windows to see what a Window's notification looked like. To me, it looks different but maybe I'm wrong.

To me, that looks like it's coming up out of the lower right corner of the task bar and is partially covering the browser window, even the right scrollbar.

I'm not a Chrome user but it seems you can turn off push notifications:

I've had Firefox ask me if it was okay for a site to send me notifications, but I've always just said no, it's not okay. Maybe I should take time to look for a way to just say no... never. :)

I think you nailed it, Richard. I followed the Chrome instructions you posted, and found solo3. I blocked its notifications, so now I just have to wait. Thanks so much!

You're welcome.

The good thing is, if you see those "push notifications" again, either on your machine or someone else's, you'll know exactly what to do. :-)

So this was junk and not from the actual programs? Mary

That's what I suspect. If true, it's not surprising they were using scare tactics.

Dr Mendelson - a medical doctor who (according to my quick search) was against vaccinations. You thought someone with such views gave worthwhile advice?

Interesting that you should pop in here to challenge me on a medical matter, Elmer. I was aware of Dr. Mendelsohn's views on vaccinations, but I didn't agree with them. Nor did I agree with everything he said. He's not the only medical author I read. But you seem to be saying that if someone has a view I disagree with, I should regard everything else they say as worthless. With today's information overload I might be tempted to do that, but I'm glad I didn't do it back then.

I was following the thread without participating in the double Windows problem (which I'd expressed some doubt about in an earlier thread) and you mentioned this doctor, not me.

Yes, I'd say that my normal attitude about "experts" and sometimes others is that when someone exhibits obviously poor judgement or extreme views, it diminishes my interest in other things they may have to say. There's no way of telling which other views are more thoughtful and well considered and which may be similarly unsupported outliers.
