Thanks for reply.
The followings are actual case of system error as you mentioned.

Type Time Source event-ID

Info 10:44:11 Service control mgr 7035
Error 10:44:05 Service control mgr 7000 …(can’t start service)
Info 10:43:52 eventlog 6005 …(related shutdown)
Info 10:43:52 eventlog 6009 …(related shutdown)
Info 10:41:05 eventlog 6006 …(related shutdown)
Info 10:41:03 Service control mgr 7035

I think, Error 7000 is not relating to the real cause of the shutdown problem.
Basically System can’t save such significant event-info under waiting status to shutdown. Suddenly I just push RESET switch by force.

By the way, it seems that below case doesn’t bring the shutdown problem although whole service providers(Network shield, P2P…etc) are enable.

  • Disable of memory scan when avast start up, in General setting menu.
