Nexus Mods and Nexus Mod Manager (NMM) are generally safe to use as long as certain precautions are followed. Nexus Mods employs multiple security checks and virus scans on all uploaded mods before making them available for download; files that fail scans are quarantined for review. This makes Nexus one of the safest and most trusted sites for mod downloads, widely used by gamers to mod Bethesda and other games. Users should always download mods directly from Nexus Mods and avoid downloading mods from untrusted sources to minimize risks. Antivirus software may sometimes flag mods as false positives due to the nature of mod files, but this is common and not necessarily an indication of malware. It is advised to keep antivirus software updated and whitelist Nexus Mod Manager if needed. Additionally, adjusting firewall settings might be necessary to allow proper functionality of the mod manager. Overall, with safe practices such as downloading from trusted sources, using updated security software, and being cautious with newly uploaded or less popular files, Nexus Mods and its mod manager tools can be used with confidence and safety.
