Malware download?!?
I very stupidly clicked on something that seamed to be a prove you are not a robot while on the Sam's Club site. How do I check to see if something bad was download?
MacBook Pro (2020 and later)
Look in your downloads folder.
Make sure your Browser preferences doesn't show any Extensions chosen.
If using Chrome, make sure your chrome://policy isn't changed to something you don't like.
Run Malwarebytes and Avast, and Etrecheck. Etrecheck has a free portion that has results you can post here, and we can help you identify if there is anything odd on your machine.
