File not scanned/not processed by size?

[Vento]

Kaav 21.3.10.391 I just did a full scan on the pc and I find for example this:

Event: Object not processed
User: xxxxxxxxxxx
User type: Active user
Application name: AcroRd32.exe
Application path: C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader
Component: File Anti-Virus
Result description: Not processed
Object type: File
Object name: Archer c80 US.pdf
Object path: xxxxxxxxx
Reason: Size

Or this

Event: Object not processed
User: xxxxxxxxx

User type: Active user
Application name: msiexec.exe
Application path: C:\Windows\System32
Component: File Anti-Virus
Result description: Not processed
Object type: File
Object name: 89d364.msi
Object path: C:\Windows\Installer
Reason: Size

 

Why not scan it?

Size? What does this mean exactly?
