Yes, NeoForge is safe. It is an open source Minecraft mod loader forked from Minecraft Forge, and it is maintained by many of the same developers who built Forge in the first place. It is not malware, not a virus, and not a sketchy third party tool.
What Is NeoForge?
NeoForge is a mod loader for Minecraft Java Edition. If you have used Forge before, NeoForge will feel familiar because it started as a direct fork of the Forge project in mid-2023. The split happened after disagreements within the Forge team about project direction and governance. Most of the active Forge maintainers moved to NeoForge, which is why development on the old Forge project slowed down while NeoForge picked up speed.
NeoForge lets you install and run mods the same way Forge does. You install it, point your launcher at it, and drop mods into the mods folder. The mod ecosystem has been gradually shifting, and many mod authors now publish for NeoForge alongside or instead of Forge, especially for newer Minecraft versions.
Who Maintains NeoForge?
NeoForge is maintained by the NeoForged team, which includes cpw, SciWhiz12, and other longtime Forge contributors. These are people who spent years building Forge's mod loading system. The project is hosted on GitHub under the NeoForged organization, and all development happens in the open. Pull requests, issues, and decisions are publicly visible.
This matters for safety. When the people behind a mod loader are known, publicly accountable, and working in the open, the risk of hidden malicious code is essentially zero. Hundreds of developers review and contribute to the codebase.
How to Verify You Downloaded the Real NeoForge
The biggest actual risk is not NeoForge itself. It is downloading a fake version from a scam site. Here is how to make sure you have the real thing:
- Download from the official site only. The official NeoForge site is neoforged.net. Bookmark it. Do not Google "NeoForge download" and click the first ad result. Sponsored search results have been used to push fake mod loaders before
- Use a trusted launcher. Prism Launcher, the CurseForge app, and the Modrinth app all support NeoForge and will download the correct version automatically. This is the easiest way to avoid fake downloads entirely
- Check file hashes. NeoForge publishes checksums for its installer files. If you download manually, compare the SHA-256 hash of your downloaded file against the one listed on the official site
- Avoid reupload sites. If a site is offering NeoForge as a zip file on Mediafire, Google Drive, or some random download portal, do not use it. The official installer is distributed through neoforged.net and Maven repositories
NeoForge vs Forge: Safety Comparison
| NeoForge | Forge | |
|---|---|---|
| Open source | Yes (GitHub) | Yes (GitHub) |
| Active development | Yes, frequent updates | Slowed significantly |
| Known maintainers | Former Forge core team | Reduced team |
| Malware history | None | None |
| Supported by major launchers | Yes | Yes |
| Mod availability (1.21+) | Growing fast | Declining |
Both NeoForge and Forge are safe mod loaders with no history of malware. The practical difference in 2026 is that NeoForge gets more active development, more mod author support on recent Minecraft versions, and faster bug fixes. Forge is still maintained for older Minecraft versions but sees fewer updates for new ones.
If you are starting a new modded world on Minecraft 1.21 or later, NeoForge is the better choice simply because more mods target it. For older versions like 1.20.1 or 1.16.5, Forge still has the larger mod library.
Why Does My Antivirus Flag NeoForge?
This is one of the most common reasons people search "is NeoForge a virus." Antivirus software, especially Windows Defender, sometimes flags NeoForge's installer or runtime files. Here is why:
Java-based installers trigger heuristic scans. NeoForge's installer is a Java .jar file. Antivirus tools often flag .jar files generically because they can contain executable code. This is a false positive. The same thing happens with Forge, Fabric, Quilt, and basically every Minecraft mod loader.
The installer modifies Minecraft's directory structure. NeoForge needs to install libraries and modify the launcher profile. Antivirus software sometimes interprets these file system changes as suspicious behavior, even though they are completely normal for a mod loader.
SmartScreen warnings on Windows. The NeoForge installer may not have a paid code signing certificate that Windows recognizes. This triggers a "Windows protected your PC" popup. You can safely click "More info" and then "Run anyway" as long as you downloaded from the official site.
If your antivirus flags NeoForge, check that you downloaded from neoforged.net, then add an exception for the file. You can also upload the file to VirusTotal to see a multi-engine scan result. Legitimate NeoForge installers will show 0 or 1 detections out of 70+ engines, which is typical for Java-based tools.
Where to Get Mods Safely for NeoForge
NeoForge itself is just the loader. The mods you install on top of it are where you need to stay careful. Stick to these two platforms:
Modrinth (modrinth.com) scans uploads, reviews new projects before listing, and is open source. It has excellent NeoForge mod coverage and lets you filter by loader and Minecraft version.
CurseForge (curseforge.com) has the largest mod library and also scans uploads. After the fractureiser incident in 2023, CurseForge tightened security significantly.
Do not download mods from random websites, Discord servers, or reupload portals. Even if someone shares a "working mod" in a Discord channel, download it from Modrinth or CurseForge instead. The extra 30 seconds could save you from a compromised file.
FAQ
Is NeoForge safe to use? Yes. NeoForge is open source, maintained by known developers, and has no history of malware or security incidents.
Is NeoForge a virus? No. NeoForge is a legitimate, open source Minecraft mod loader. Antivirus false positives are common with Java-based tools but do not indicate actual malware.
Is NeoForge safer than Forge? Both are equally safe from a security standpoint. NeoForge has more active development in 2026, which means faster security patches if a vulnerability were found.
Can NeoForge mods have viruses? Any code you run can theoretically be malicious. Download mods only from Modrinth or CurseForge, check download counts, and prefer mods with public source code.
Should I switch from Forge to NeoForge? For Minecraft 1.21 and newer, yes. Most mod authors have moved to NeoForge for recent versions. For older Minecraft versions, Forge still works fine and has broad mod support.
Is the NeoForge installer safe? Yes, when downloaded from neoforged.net. Do not download the installer from third party sites.
Why did NeoForge split from Forge? Disagreements about project governance and development direction in 2023. Most of the active Forge maintainers moved to NeoForge, which is why it receives more active development.
Running a Modded NeoForge Server?
If you are setting up a NeoForge server for your friends or community, you want hardware that can actually handle modpacks without lag spikes every time someone loads a new chunk. Space-Node offers Minecraft server hosting with NVMe storage, instant modpack installation, and a free subdomain. Plans start at just a few euros per month.
