I thought he did address your issue, here http://forum.avast.com/index.php?topic=29566.msg243874#msg243874.

OK so anyway, I saw a user post concerns that Spyware Terminator taking up X gigabytes on the computer. This is a bug which has been in existence for a while now. However we addressed this bug and it should be fixed in our current FINAL version of 2.0 which I linked above. It should read correctly now in Add/Remove Programs in the range of 30MB or so. Spyware Terminator has never taken more than 1GB of space, let alone 100MB, let alone 50MB... Tongue.

Also the best place to have addressed that problem surely would have been the ST forums.
