I received a call from a guy who is Indian, he said he work for Microsoft at Connecticut, and my computer was hack.  I knew this is a scam, because they had called me 2 months ago.  I just ask him what time is at Connecticut now, he said 6:30pm, and same time at California
6:30pm.  I told him you a liar, you are BS...  you call me from India, from New Deli, not from Connecticut.  But he still insist me to open my computer and try to type r and so on...  This is a really scam.  DO NOT DO WHAT THEY TOLD YOU TO DO! (I call back, no answer!)
