My family and I have been using Free Avast! Antivirus for decades now: Windows 98SE, Windows XP, Windows 10, and Windows 11 and believe me, Avast! antivirus is best... free or pay. I even have a vintage Windows 98SE laptop, just for fun, and even the vintage Avast! Home Edition 4.8.1368 virus definitions updates can still be downloaded directly from Avast. I highly recommend Avast!
