World saving taking a long time and causing internal server lag (caused by F-Secure / DeepGuard)

Hello, thanks for reporting this! To help us fix this issue could you please do the following if you're affected:

• Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report ([minecraft/crash-reports/crash-<DATE>-client.txt|https://minecrafthopper.net/help/finding-minecraft-data-folder/]) here.

• Please attach the affected (zipped) world file. If the file size is too large, please upload it somewhere else and then link to it here.

• While the world saving occurs and the game doesn't respond, please press F3 + L once, then wait a short moment until profiling has finished.
  Afterwards, please attach the generated .zip file containing the profiling results here. The file path is shown in chat; the file can be found in [minecraft/debug/profiling/<DATE>.zip|https://minecrafthopper.net/help/finding-minecraft-data-folder/].

• If you are playing on a server please additionally run the command /perf start to create a profiling report for the server. In case you do not have the permission to run this command, make sure that you're a server operator.
  Once profiling has finished, please attach the generated .zip file from debug/profiling/<DATE>.zip of the server folder.

I hope that with this additional information we can find out what's causing the world saving to take so long and make your world unresponsive. Thanks in advance!
