Your antivirus software is your first line of defense. The integrity of its update files is paramount. While many community-sourced servers have provided a free lifeline for users over the years, they operate outside of ESET's control and cannot be fully trusted for long-term security.

: Without these updates, an antivirus is completely blind to newly released zero-day exploits and ransomware variants.
