AIS a/v definitions question

Avast Free Antivirus / Premium Security
1

Do definition updates over write previous definitions or do they all accumulate? In other words do they take up more space on the hard drive?

2

The definitions do grow over time - then an update will prune them all down, as malware disappears or merges with other types
But the actual space taken (considering todays hard drive sizes) is minimal
