Most likely someone running the "Windows Tech Support" scam. The caller will try to convince you that they are from or associated with Microsoft, that your computer is sending them error messages or is downloading suspicious files or is full of viruses and malware. They then want to take remote control of your computer to "fix" the problems. While on your computer they will install their own malware, install a boot password, then charge you money to clean up the mess, most likely leaving a back door or keylogger so they can steal personal information. Do not ever let anyone who colds calls you about a supposed computer problem have access to your computer. It is all a scam.
