Newbie - Filtering A Query

Hi All

I am writing a query to list all users in 2 countries but exclude users which their name starts with _inactive_5#4$66899, holder_....

I wrote

Select position, subsidiaryName
from position
where subsidiaryname = 'country one' OR subsidiaryname= 'country 2'

I get a result but there are some names which are fake accounts

eg. names start with inactive_#@$%&*ijkgfhg

or with holder_uhgfjgj

how can I do write into the query so that only the proper names without the rows that are fake showing up. In other words i want all results for those 2 countries except ones starting with inactive or with holder......?

thank you:)
