Adobe AIR Kaspersky warning

My Kaspersky anti virus has shown a warning "Protection may be at risk. 1 warning". When I click on "Details" it says

"1 important update is available. Install all important updates to stay protected".

When I click on "Show" it lists "Adobe AIR Vendor Adobe Systems Version 3.1.0.4880 arrow head 23.0.0.257".

I clicked "Update all" several times but if then says "Failed to update. Unknown error?

I tried to update the software on Adobe's website but it wouldn't work.

Do I need Adobe AIR? Should I uninstall it or is there some way to fix it please?
