This message means Roblox detected software that may be interfering with or changing the client. Close Roblox, exit overlays, auto-clickers, unofficial launchers, debuggers, injectors, or other tools that interact with Roblox, then restart Windows and launch the official unmodified app. Do not bypass the check or weaken Windows security; repeated modified-client use can lead to account restrictions.
Copy the full warning and any code before changing software. A modified-version warning, a process-suspended message, and an antivirus false positive have different supported actions.
2
Remove any modified Roblox client
If the message says a modified Roblox version was used, uninstall that unofficial version and reinstall Roblox from Roblox.com or an official app store. Do not use a bypass, injector, modified executable, or unofficial client; Roblox says continued use may cause more account restrictions.
3
Close software that interacts with Roblox
Exit Roblox, then close auto-clickers, unofficial launchers, overlays, debuggers, injectors, macro tools, or other software you know is interacting with Roblox. Do not assume a named security or anti-cheat app is responsible unless the clean test identifies it.
4
Resolve an explicit security-software block
If antivirus or endpoint security specifically flags official Roblox, update the security software, report the file as a false positive where appropriate, and allow official Roblox through that product's supported controls. Do not disable Windows Security, the firewall, Exploit Protection, or Memory Integrity as a generic fix.
5
Use a clean boot for the process-suspended message
If Roblox says it was stopped and third-party software must not interfere, follow Microsoft's clean-boot procedure linked by Roblox: hide Microsoft services before disabling the remaining services and startup items, restart, then test the official client. Record what you changed so normal startup can be restored afterward.
6
Identify the interfering program
If Roblox works in the clean boot, re-enable the disabled services and startup items in small groups, restarting and retesting between groups. When the warning returns, leave the identified conflicting program closed while using Roblox or uninstall it if you do not need it; then restore the other items.
7
Verify the result or contact Roblox
Launch an experience from the official unmodified client. Success means the experience opens without the same warning and normal Windows startup can be restored without the identified conflict. If the warning remains even in a clean boot, send Roblox Support the exact message, code, install source, and tested software list.
If it does not work
If the message names an emulator, debug mode, or another specific anti-cheat condition, follow that exact branch in Roblox's current Anti-cheat Messages article instead of applying unrelated launch repairs.
If the warning appears only with an unofficial launcher or client modification, remove it and retest the official client; reinstalling the same modified build is not a repair.
If a security product alone blocks official Roblox, keep protection enabled and use its vendor's false-positive or allow process.
If you cannot identify a conflict after the clean-boot comparison, restore normal startup and give Roblox Support the comparison result rather than leaving Windows in a diagnostic state.
