Hello denicelevay,
Never trust anyone claiming they are from Microsoft. Microsoft will never call you and ask for remote control access of your computer. Did the man from AMMYY administration tell you to install a remote control software? If they did, I recommend uninstalling the program to prevent this man from having remote access to your computer. To uninstall the program, go to the control panel. Inside of the control panel under the programs section, click on uninstall a program. This will bring up a list of programs. Find the program and click uninstall. Maybe he installed a virus on your computer? To make sure, I recommend downloading and installing Microsoft Security Essentials to scan and clean your computer. I will provide you with the download link below.
