Is uplay_r1_loader64.dll safe?

Verdict
Suspicious

One tier-1 trojan detection and possible T1055 process injection warrant caution, but broad historical prevalence and limited engine agreement prevent a definitive family attribution.

The DLL has mixed evidence: 5 of 75 engines flagged it, with one tier-1 generic-trojan detection, and a sandbox mapped activity to T1055 process injection. However, most tier-1 engines did not detect it, no sandbox issued a malware finding, and the sample has circulated broadly since 2014.

Do not use it until verified

Quarantine the DLL if it was not installed by a verified official source, and repair or reinstall the associated software from its official channel. Keep endpoint protection enabled and avoid manually loading the file.

01

Before using

Do not use it until the source and publisher can be verified independently.

02

If you already used it

Stop using it, scan the device, and watch for unexpected behavior or security alerts. Reinstall the parent software from the developer's official site instead of replacing this component by itself.

Analyst conclusion

The DLL has mixed evidence: 5 of 75 engines flagged it, with one tier-1 generic-trojan detection, and a sandbox mapped activity to T1055 process injection. However, most tier-1 engines did not detect it, no sandbox issued a malware finding, and the sample has circulated broadly since 2014.

Where this verdict could be wrong4 caveats
  • Only 5/75 engines detected the DLL, and 15 tier-1 engines reported it undetected; this leaves substantial false-positive potential.
  • behaviour.hasMaliciousSandboxVerdict=false, with no persistence indicators or dropped file hashes recorded in the single sandbox run.
  • The file has 1,153 submitters and 1,444 submissions over more than eleven years, indicating broad historical circulation.
  • A community comment mentions VMProtect-related obfuscation, but it has zero votes and externalIntel.yaraify was skipped, so it is not independently corroborated.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Recommended action

Quarantine the DLL if it was not installed by a verified official source, and repair or reinstall the associated software from its official channel. Keep endpoint protection enabled and avoid manually loading the file.

What this file does

Observed actions and their security significance

  • High concern: Injected code into another process, a technique that can conceal execution.

  • High concern: Manipulated how the operating system loads code, which can redirect execution.

  • Moderate concern: Contained obfuscated or packed code that makes inspection harder.

  • Moderate concern: Checked the environment for virtualisation or analysis tools.

  • Note: Collects details about your system.

These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.

What to do now

We couldn't fully clear this file. Treat it with caution.

  1. Recovery step 01

    Don't use it unless you're certain it came from a source you trust.

  2. Recovery step 02

    Check where you got it — an unexpected attachment or a random download link is a red flag.

  3. Recovery step 03

    Do not delete or replace the component manually. Quarantine it with your antivirus or repair the parent software from its official source. Reinstall the parent software from the developer's official site instead of replacing this component by itself.

  4. Recovery step 04

    If you're still unsure, scan it again in a day or two — detections often catch up on newer files.

8 evidence-based answers
Is uplay_r1_loader64.dll safe, or is it malware?
Evidence-based answer
uplay_r1_loader64.dll is suspicious — treat it as unsafe until you're sure. 5 of 75 antivirus engines flag it; that detection signal contributes to the cautious verdict. Don't use it unless you fully trust where it came from. Reinstall the parent software from the developer's official site instead of replacing this component by itself.
What is uplay_r1_loader64.dll?
Evidence-based answer
uplay_r1_loader64.dll is a Windows library or loadable module, about 502 KB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
How many antivirus engines detected uplay_r1_loader64.dll?
Evidence-based answer
5 of 75 antivirus engines flagged uplay_r1_loader64.dll, 5 of them as outright malicious. The raw count alone does not establish safety or danger; we also weigh which engines flagged it and corroborating behavior, identity, reputation, and rule evidence.
I already downloaded and used uplay_r1_loader64.dll — what should I do?
Evidence-based answer
Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
How do I remove uplay_r1_loader64.dll?
Evidence-based answer
To remove uplay_r1_loader64.dll: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Quarantine this component with your antivirus, then repair or reinstall the parent software from its official source. Do not delete or replace the component manually. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
What kind of malware is uplay_r1_loader64.dll?
Evidence-based answer
uplay_r1_loader64.dll is classified as a trojan — malware disguised as something harmless to trick you into running it. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
What is the SHA-256 hash of uplay_r1_loader64.dll?
Evidence-based answer
The SHA-256 hash of uplay_r1_loader64.dll is 4c77344481222f5537d1f0776f0a3f86f6724d57ede0590c72b0ff97e99ccb1d, and its MD5 is e15acddcf04f501c7c28e152d8b2f007. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
How up to date is this analysis of uplay_r1_loader64.dll?
Evidence-based answer
This report reflects the scan run on September 8, 2026. Because a file's hash never changes, the identity of uplay_r1_loader64.dll is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
