Hi,
Are those antivirus apps installed? If not, it sounds like you're getting fake virus alert notifications. This might be caused by notifications from your browser. If you're using Edge, go to its Settings >Privacy, search, and services > Site permissions > All permissions > Notifications. Under the Allowed to send notifications, make sure all websites are removed or blocked by selecting the option given when you click the three dots next to them.
To help prevent this from happening again, I recommend paying close attention to website popups, especially those asking for permission to show notifications. It's also a good idea to install a good ad blocker to reduce intrusive ads and help avoid misleading popups on websites like this one.
