What it means
SD codes are special detections a server can switch on. Most of them are about the environment MTA is running in: a virtual machine, a blocked component, or a program that can change how the game runs. MTA's own documentation gives this code as Data integrity.
How to fix it
Work down the list and stop when it is solved.
Read the whole message, then the official page
The number names a detection category, not a program on your computer. MTA's anti-cheat guide lists what each category covers, and the full message is what tells you which case you are in.
Close what the message names
If the message names a program, close it completely, then start MTA again. Some of these programs keep a background service running, so check that it has really stopped.
Use the official client and clean game files
Install MTA from multitheftauto.com and keep GTA unmodified. Trainers, injected DLLs and patched game files are exactly what these checks look for.
If you were banned, appeal where it was issued
A server ban is appealed on that server. An MTA global ban is appealed through MTA's own process. Keep the full message: it names who issued it.
MTA's anti-cheat guide publishes the category, not the detector. The guide itself says the list is incomplete and that a detection does not prove intent. Keep the whole message: the part after the code is what tells you which case you are in.
Still stuck? The Fix tool reads MTA's own log on your computer and points at the matching steps. Nothing is uploaded.
