I thought about these issue and I think I know exactly what is going on.
@Avethil - do you have TONS of command lines in CyberLock Settings? The reason I ask is because with the new Command Line feature, after the new version is installed, CyberLock will update the C:\ProgramData\CyberLock\commandlines.db database to add the new columns it is now using. Then it will compute the hashes of the command lines and backfill all of these new columns, which would explain the high disk usage and the tray icons not appearing until the task was complete. On my system, I have 70 or so command lines, and the process took less than a second. But if you have an ungodly amount of command lines, I suppose it could take a couple of minutes. And once it is finished, it does not have to update the databases again.
So I would try the original 9.02 again and give it a couple of minutes. If that does not work, try 9.02b, but I doubt that the LOCKED label change broke anything.
As far as the errors
@simmerskool was experiencing, I think these are just simple false positives from the new version of DeepInstinct. Believe me, I know all about how making changes to the models create false positives until you get it right

.
So I am quite certain this is what is going on in both cases, and that the original 9.02 is perfectly stable and ready for release. The only question is if the LOCKED label change is causing an issue or not, but you have both versions, so we should know as soon as you try both versions.
BTW, the LOCKED label fix was simply a bug in Windows where when the user double clicks on a label, like the LOCKED / UNLOCKED label on the CyberLock Desktop Gadget, the Windows Clipboard will populate with the word LOCKED or UNLOCKED, so when the user pastes something the next time, it will paste the word LOCKED or UNLOCKED. I always wondered why that happened, and since I have been fixing all of the silly minor issues, I figured I would fix that issue as well. It turned out to be a known bug in Windows, and the fix is super simple, so I implemented the fix. But if it is going to cause issues, we can just leave it as it was.
