 ! Description: Most anti-malware lists are pretty big and can cover a 5- or 6-digit amount of specific domains. But my list hereby claims to remove more than 25% of all known malware sites with just a 2-digit amount of entries. This is mostly done by blocking top-level domains that have become devastatingly abused by spammers, usually because they allowed for free and uncontrolled domain registrations. There's also additional categories that cover unusual malware and phishing domains that very few other lists seem to cover.
 ! For other security-specific lists I've made, check out https://github.com/DandelionSprout/adfilt/tree/master/Special%20security%20lists
