PLEASE HELP - I am trying to create a new Opportunity but I keep getting this error message:

Error: Invalid Data. Review all error messages below to correct your data. Apex trigger trg_Opportunity caused an unexpected exception, contact your administrator: trg_Opportunity: execution of BeforeInsert caused by: System.QueryException: Non-selective query against large object type (more than 100000 rows). Consider an indexed filter or contact salesforce.com about custom indexing. Even if a field is indexed a filter might still not be selective when: 1. The filter value includes null (for instance binding with a list that contains null) 2. Data skew exists whereby the number of matching rows is very large (for instance, filtering for a particular foreign key value that occurs many times): Trigger.trg_Opportunity: line 15, column 1

...I was told that it has to do with an APEX trigger that I have set. I do not know how to go about turning off the APEX trigger or if there is something I can modify to allow the creation of manual Opportunities.

Please Advise.
