今天，一开启浏览器瑞星反复提醒有进程修改下面的注册表，请帮忙看看怎么回事，多谢！
进程C:\ProgramFiles\InternetExplorer\iexplore.exe
试图修改注册表的内容：
HKEY_CLASSES_ROOT\.HTM\OPENWITHLIST\MICROSOFTOFFICE\ \EXCEL\SHELL\EDIT\DDEEXEC\TOPIC
HKEY_CLASSES_ROOT\.HTM\OPENWITHLIST\MICROSOFTOFFICE \EXCEL\SHELL\EDIT\DDEEXEC\APPLICATION
HKEY_CLASSES_ROOT\.HTM\OPENWITHLIST\MICROSOFTOFFICE \EXCEL\SHELL\EDIT\DDEEXEC
HKEY_CLASSES_ROOT\.HTM\OPENWITHLIST\MICROSOFTOFFICE\ EXCEL\SHELL\EDIT\COMMAND
等等，还有16项
