Comments 
QAZ Trojan is the trojan believed to have infected Microsoft. When analyzing the file we found references to move notepad.exe to note.com and name the trojan itself to notepad.exe. However, upon actual testing our version of the QAZ Trojan, it did not replace the notepad.exe. So, if you have a note.com file it probably is your real notepad.exe. Once the QAZ Trojan has infected one computer it looks for other shared hard drives and attempts to infect them. It then emails to a Russian address and waits for a connection.
