No. Absolutely not.

The legitimate Vulkan Runtime Libraries entry is not malware. However, because the name sounds technical and unfamiliar, malicious software authors have occasionally disguised viruses with similar names. Here is how to verify you have the real version:

| Myth | Fact | |------|------| | “Vulkan is a virus.” | No. It is an industry-standard graphics API. | | “It slows down my PC.” | No. It sits idle until a Vulkan app runs. | | “I don’t play games, so I don’t need it.” | Some CAD software and media players also use Vulkan. | | “Version 1.0.39.1 is too old to be safe.” | It is safe, but outdated. Updating drivers fixes that. |

New drivers always include the latest stable Vulkan runtime supported by your GPU.

After this deep dive, here is the final, actionable advice:

| Your Scenario | Action | |------------------|-------------| | You have a modern GPU (GTX 10-series or newer, RX 400-series or newer, Intel 8th gen or newer) and keep drivers updated. | Uninstall 1.0.39.1 safely. Your newer Vulkan runtime (1.2+) handles everything. | | You have an older GPU that just barely supports Vulkan 1.0, and newer drivers are no longer available. | Keep 1.0.39.1. It may be the only working Vulkan runtime for your system. | | You are unsure if any app needs Vulkan. | Leave it. Storage space is cheap (under 200 MB). Removing it risks breaking games without meaningful gain. | | You see high CPU/GPU activity from vulkan-1.dll and suspect malware. | Verify the digital signature. If invalid, run a full antivirus scan (Windows Defender suffices). If valid, the issue lies elsewhere. |

If you’ve recently browsed through your list of installed programs on Windows—whether on Windows 10 or Windows 11—you might have spotted an entry named “Vulkan Run Time Libraries 1.0.39.1” and wondered: Is this bloatware? Is it a virus? Do I need it?

The short answer: It is not a virus, it is not bloatware, and you should keep it.
