Transaction Log won't shrink, DB thinks it is replicating

I've got a database MSSQL2008R2Express DB running Kaspersky Security Center, and I have no idea under what circumstances the install happened, but the database appears to think that it's being replicated and will not free any space from the transaction log.

eg:

USE master;
SELECT name, log_reuse_wait, log_reuse_wait_desc FROM sys.databases WHERE name = 'KAV';
SELECT DATABASEPROPERTYEX('KAV', 'IsPublished');

returns:

KAV,6,REPLICATION
0 [not published]

Also there's nothing listed in the Replication section in SSMS.

So far I've tried a couple statements gleaned from Google results:

USE KAV;
EXEC sp_repldone null, null, 0,0,1;
EXEC sp_removedbreplication KAV;

But I've had no luck in getting this DB to stop thinking its being replicated.
