Analysis of malicious code identifies a function that searches for specific processes and hardware on a victim host. If the processes or hardware are found, the malicious executable does not install i

Security researchers and automated sandboxes typically analyze malware inside virtual machines or emulated environments. Malware developers add checks for VM-specific processes (e.g., vmtoolsd.exe, vboxservice.exe) and hardware artifacts (e.g., virtual network adapters, low disk space) to detect these environments. If a VM or sandbox is detected, the malware aborts installation to prevent behavioral analysis and signature creation by security researchers.

Remote code execution is an attack capability that allows code to run on a remote system; it is not related to the self-preservation check described in the question.

Polymorphic code refers to malware that mutates its own code to evade signature-based detection, which is a different technique unrelated to environmental hardware or process checks.

Disabling antivirus is an action a malware takes after it has already installed itself, not a reason to abort installation before it begins.
