Constant Security Blocks

Due to continuing computer problems, I am behind here for several days,so this topic may have been discussed. My tech did a fantastic job a few days ago of restoring many of my previous settings that had been overridden for reasons unknown.

An example of this problem: I was reading email using my Pixel10Pro because the a block prevented me from entering a new password, for reading on the computer, many of mine no longer valid. (I was pleased that I was able to log on here with no problem.) I was reading an email from my son, which had a link to an attachment about a bear invading a house in Crested Butte, Colorado. We lived there. where I had spent twenty-seven months creating, and serving as fire chief, the Crested Butte Fire Protection District. To my dismay, I was blocked by yet another security warning. (As of now, my only image of such blocks is in my Pixel; I will try to post one here if my software will allow me to capture and convert it into a postable image.)

As i usually remember to do, herewith my advance appreciation for any assistance in finding and fixing the cause.

A search for "Bear In Crested Butte" will provide valid links to the news reports of the devastation caused by the now euthanized beast.
