<prompt> Human: Here is the story he told me. Plenty of red flags but Im interested if anyone has any experience with a similar situation.So essentially a few months ago my friend purchased a 5 year anti viruscomputer protection service from a company called Yale Vision. I googled around and can not seem to find this company first of all. My friend goes ahead and pays 400 wtf who pays 400 for antivirus?? for 5 years of service.Fast forward to yesterday, few months after purchase, someone supposedly from the company calls my friend and explains that they are going out of business and he is owed a refund. So after a long drawn out process, the rep transfers the refund to my friends bank account. He was supposed to get 400 and he realizes the rep sent him 4000. So my friend goes Hey man you sent me 4000 not 400. Cue the rep freaking out, getting management on the line, freaking out. They go on to ask him to go to the nearest Walmart and transfer them the money right now to avoid any delays because they need their money back.My friend, thinking he just hit community chest in monopoly, essentially tells them to kick rocks and hangs up. They call back, he doesnt answer and goes on to block them. He is pretty convinced that it was some sort of error on their part and this money is his now.To me, this sounds like one of the fake check scams where you end up over drawing your account and getting robbed but I dont know. Did my friend just make a 4000 come up or is he as gullible as I think he is? If the company did make a mistake, can he legally keep the money? Is he going to be taken to court if the firm did make an error like that?EDIT: Did not expect this to blow up the way it did. I told him from the jump this is a major scam and I really appreciate everyone bringing to light some of the potential threats I did not consider. I made this post for my friend to see to hopefully convince him to take action. I believe it has to an extent, he will be going to his bank today. I will keep the post updated.  <response>: Your friend is not only being scammed, he has been scammed and is in the process of being scammed again.Here is information on the original scam, make sure he sees this so it shows the whole thing started as a scam.He has to tell the bank right away.
