When you connect Jun to your computer for the 1st time after you find her. It makes the Report 3 txt. Looking at Report 1, the date is 12.12, time 15:21. Which is very close to the 1st Journal you brought up, 1578 12 12. I don't know what the 1578 is. Can't be the time, otherwise it should be 1618 because you can't go past 60mins. Unless its some kind of code. Report 2 happens on 12.21, at corrupted time of Y2W5:??. So the 2nd Report happens after the other 2 Journals, being on the 16th and 18th.
Looks like after Jun killed something/someone the Creator sent a remote shutdown so he could tried to "fix" the code, Jun didn't like that and decided the probability of being shutdown again was high. So she tried to rewrite the Asimov3 file, was denied. She tried to Delete it, was denied. She then sent a power surge to the specific spot on the hard drive the file was located just to corrupt it. After it was corrupted, she was able to delete it. Over the next week the Creator installs new parameters and thinks everything is "working well so far". It's not. So the Creator tried to use malware to fix it. Jun unable to fix or prevent what's happening right away, creates a new antivirus software. Jun then realizes that she is under physical attack and Neutralizes the problem. The new antivirus doesn't have enough time to work before she shuts down as a result of the damages from the malware and the physical. And the next time Jun is powered on is by the MC
The file F:\Jun\destroyer.vi*M2$7.ess is corrupted. Unless we can get the actual name we won't know what it is. It could be what Jun designated her attacker. "The Destroyer gained remote access". But there is a lot of corruption on the Report 2. And it doesn't look like a letter cipher. Report 3 tells you that the F drive is 78% corrupted, and another 4% crossed the other 3 drives. That's what takes Jun so long to talk
