These scammers called my 88 year old father, and managed to talk him in to attempting to install some malware. He isn't terribly computer literate, and Windows confuses the heck out of him (switched him to Chromebooks - so much better, but I digress). Anyhow, after spending almost an hour with him, they hung up in frustration - as he could not follow their directions to get the malware installed. So Windows is secure after all.
