This actually happened to a mother of a friend I know and their computer got messed up pretty bad. It's great to see you were visiting for the holidays - they may of possibly went through with it if there wasn't a techie around. Seems social engineering is far from going anywhere! Your story made me recall a phone call to my mom where the person just flat-out asked for her credit card for them to continue through with some order she purchased. This of course was awhile back and she ended up hanging up the phone, but it makes you wonder how many people actually fall for these types of calls. Happy holidays, thanks for the share.
