Permanently Drop database triggers from tempdb

We installed an security  application that created  database triggers in all the databases to include tempdb.  We have found that the database triggers in tempdb are causing out main transactional application problems.  We have manually dropped the triggers from tempdb, but when we reboot the server, or restart SQL Server the database triggers come back and we have to drop them again.

What is the proper/best way to permanently drop these database triggers from tempdb?

We are running SQL Server 2005, 2008 R2 and SQL Server 2012.

Thanks.
