?about contents of history and what it means

I can not supply more info than what I am about to give you as I reinstalled last night and wiped out history.

 

 

Unauthorized access logged (open process)

DETAILED as

ACTOR- c:\windows\system\drwtsn32.exe

ACTOR- PID

TARGET- C:\Programfiles\CommonFiles.............. (also the lower case f is accurate)

 

 

Unauthorized access blocked (Send Terminate message to window)

Detailed

ACTOR- c:\windows\system32\ctfmon.exe

TARGET- C:\ProgramFiles\NortonInternetSecurity\Engine\16.0.0.125\ccSudtst.eue      .......(I wrote .eue. Googled it and nothing, it asked exe so googled that still nothing)

REACTION- Unauthorized access blocked

 

 

There are 3 more Unauthorized access   1:logged open thread

                                                                   2:Blocked only suspend thread

                                                                   3:Blocked  Send Terminate message to window

 

 

What do these mean?

The same day had 4 attacking computers.............I found that they are from China. Does not bother me as they are being blocked but the above I truly do not understand. Any info would be appreciated.
