For example against malware and exploits.
Does anyone know what it is used for or does anyone have false positives?

Svchost.exe is a crucial system process in Windows that hosts multiple Windows services. It is responsible for launching and managing these services, which are essential for the proper functioning of the operating system. However, since Svchost.exe is a common process used by both legitimate services and potential malware, it has been targeted by malware authors to disguise their malicious activities.

To mitigate the risks associated with Svchost.exe, Windows provides several options for protection. These options include:

1. Windows Defender Antivirus: Windows Defender, the built-in antivirus solution in Windows, is capable of detecting and removing various types of malware, including those that may disguise themselves as Svchost.exe processes.

2. Windows Firewall: The Windows Firewall helps protect your computer from unauthorized network access and can block suspicious network traffic associated with malicious activities.

3. Windows Update: Keeping your operating system and software up to date is crucial for security. Windows Update ensures that you have the latest security patches and fixes, reducing the chances of malware exploiting vulnerabilities in Svchost.exe or other components.

4. User Account Control (UAC): UAC prompts you for permission when a program requires administrative privileges. This helps prevent unauthorized changes to your system, including potential attacks that target Svchost.exe.

While these mitigation options provide meaningful protection against malware and exploits, it's important to note that no security measure is foolproof. New malware variants and sophisticated exploits are constantly being developed, and it's crucial to maintain a layered approach to security. This includes using reputable antivirus software, practicing safe browsing habits, avoiding suspicious downloads, and regularly backing up your data.

As for false positives, it is possible for security software to flag legitimate Svchost.exe processes as potentially malicious. This can occur due to false heuristics or outdated virus definitions. However, reputable antivirus software vendors continually update their databases to minimize false positives and ensure accurate detection. If you encounter false positives, you can report them to your antivirus vendor for investigation and resolution.

Do you mean GpEdit > Computer Configuration > Administrative Templates > System > Service Control Manager > Security Settings > Enable svchost mitigation options ?
I have this Enabled. First, this is MS provided setting, so it is safe. Second, svchost mostly just start services. While some services are installed by 3rd party vendors, most of the services belongs to Windows. Just enable it.

See Microsoft's documentation

This policy setting enables process mitigation options on svchost.exe processes.
  • If you enable this policy setting, built-in system services hosted in svchost.exe processes will have stricter security policies enabled on them.
This includes a policy requiring all binaries loaded in these processes to be signed by microsoft, as well as a policy disallowing dynamically-generated code.
  • If you disable or don't configure this policy setting, these stricter security settings won't be applied.
If you enable this policy, it adds code integrity guard (CIG) and arbitrary code guard (ACG) enforcement and other process mitigation/code integrity policies to SVCHOST processes.
