from how I read it, seems a virus is most likely causing all the abnormal changes on your system. when you install adobe reader, it shouldn't affect and change all other programs, only a virus will do such activity. Perform a system scan and ensure you're using a reliable anti-virus to disinfect your system. In addition, you'll probably be needing this software that helps fix Adobe Reader program errors
