Hello. Whenever I open Microsoft Word or Powerpoint my computer becomes unresponsive or freezes. I can't even close the program with the Task Manager! I've scanned my whole computer with Super Anti Spyware, Malwarebytes Anti Malware, and McAfee Total Protection. Only Super Anti Spyware found quite a large number of adware tracking cookies, but these were removed and the issue still persists. The program is called Microsoft Office 365 ProPlus -en -us. My operating system is Windows 8.1.
