unauthorized access logged

I JUST did some sort of update to java from the java website and JUST as I was updating it I have 2 unathorized access logged

 

c/windows/installer/msibb99.tmp

 

users/appdata/local/temp/msid606.tmp

 

Both are targeting---- c/program files/norton internet security/engine/ccsvhst.exe

 

RISK_ MEDIUM

 

I would think that this is normal but I just want to make sure
