Hello , I'm not sure this is the right section to post this topic. I've got a phone call (British accent, U.S.number, allegedly an International Agency for fighting cyber crime). Have been told that through my IP address are suspicious financial transactions going, and it's my duty to let them check it and allow them access to my computer for that.( Not this one, this is borrowed.) I've been so feeble-minded to do that. I've never learned whether there are any such transactions, but have been offered an " absolute security program working lifelong on any computer" for only $499. When I wouldn't buy it, I'll be cut off from the World wide web.This time I've expressed my meaning of this scam and interrupted the phone. Since that I never got into my Thinkpad, all of sudden it needs a password at start. I never had any such password at start, had only my mails secured with a password. My Thinkpad wasn't yet a year old and not quite cheap. Is there anything I could do to unblock it?
