OK First I applaud anyone who wants to take the time to go through and remove an infection by hand from their system. Most times it works and sometimes it fails but that's how you learn.
I wasn't aware this malware ( I am not sure I would call it a virus) is a wide scale infection. From what I just read it piggybacks on downloads of "free" software (which in most cases is an oxymoron).
That being said anyone looking for a quick, painless and complete removal of this malware , Malwarebytes does a good job.
Here you are again cndps pushing links with affiliate payouts, which makes me wonder why if Brave is so good why do they pay people to use it? Personally I find 3rd party add-ons much more trustworthy for either Chrome or Firefox and it's variants.
I use uBlock Origin, Malwarebytes browser extension and Emisoft Browser Security and nothing ever gets through. I think the last two add-ons may still be in Beta but they work like a champ and they don't seem to slow things down much if at all.
I have mellowed with time but I used to eat spammers for breakfast and enjoyed every mouthful. 419er's are tasty too but that's another story.
