yeah, usually its "theres something wrong with you windows, youll have to give us remote access to fix it", then they will put a virus and then extort money out of you to take it off,but wont, when you could just reinstall windows to get rid of it
one time i acted as if i was turning my computer on, then following their instructions, then i just said "now what?" , getting them excited thinking they actually tricked me, the just hung up
but then the next day they phoned again so i coldy had to state/yell "i know this is a f#$king scam, take my f@#king number off your list and dont call again", and i havnt received a call from them again oddly enough.
