Hello, You are safe to remove: DomainDigits1.cf Obfu1.cf
Update the FVGT_* rules and those are not needed. The domainDigits1 file was a test that doesn't have enough impact to be valuable. It needs more work and it's not likely to be much help. Make sure tripwire is up to date, it hasn't changed in a long time. The latest version seems to work pretty well. You can remove 90_FVGT.cf It's been replaced by a number of different FVGT_* files, they are located under the "other" section on the rulesemporium.com rules page.
