Unauthorized access blocked question
Vista Home Premium 32 bit desktop PC
Hoping someone can help me understand what this all means.
I do not look at the NIS history as much as I did in the past. But just renewed my 2012 NIS subscription last night, so wanted to make sure all is working well.
So I find this entry in the history log, like 42 entries
Unauthorized Access Blocked (open file)
The actor in all 42 of these events is DFRGNTFS.EXE
The targets are all Norton related(engine, MUI, program data involving Norton)
I know it's blocked so good
I did google the DFRGNTFS and it seems its a windows disk defragmenter?
In my full NIS history I do not ever see this entry and I have had NIS 2012 for a year
Also read something about it runs when new software is installed.
But u did not install new software, that makes it concerning.
Last night I did update my NIS 2012 subscription and I also installed a Microsoft Vista update that came out 8/27/13 (KB280382)
But neither if those should have installed new software
