Good morning, BW. I noticed the same thing over the weekend.
Regarding the trustworthiness of Sophos, CNET published an article last week ("The best antivirus software for 2021") that lists Sophos as a "Worthwhile subscription alternative" for the "Windows plus MacOS" platforms.
Also, Sophos is the recommended antivirus software by the Maricopa County Community College District (MCCCD). The MCCCD serves the fourth-largest county in the United States (Maricopa County, AZ) and had an enrollment of over 97,000 students during the Fall 2020 semester.
