Is paperline.exe safe?

Verdict
Suspicious

Signed executable with two low-trust PUP detections, process-injection behaviour, and direct-IP traffic to westbeavers.com.

Two tier-2 engines flag the file as PUP/ApplicUnwnt while 16 tier-1 engines remain silent. Runtime evidence shows process injection (T1055) and direct-IP connections to westbeavers.com, yet no tier-1 consensus or malicious child files exist.

Do not run it until verified

Treat the file as potentially unwanted; remove it unless its origin and purpose are explicitly trusted, and retain endpoint protection.

01

Before running

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

02

If you already ran it

Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.

Analyst conclusion

Two tier-2 engines flag the file as PUP/ApplicUnwnt while 16 tier-1 engines remain silent. Runtime evidence shows process injection (T1055) and direct-IP connections to westbeavers.com, yet no tier-1 consensus or malicious child files exist.

Where this verdict could be wrong2 caveats
  • contactedHosts.inspected=1, maliciousHosts.length=0 — no complete contacted-host reputation result was available in our cache
  • droppedChildren.hasMaliciousChild=false — both dropped children returned unknown verdicts

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

Treat the file as potentially unwanted; remove it unless its origin and purpose are explicitly trusted, and retain endpoint protection.

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: Used an input-capture technique that can record credentials or keystrokes.

  • High concern: Attempted to impair or bypass security controls.

  • 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: Communicated over a common application protocol; malware can use this for command-and-control.

  • 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 run 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

    If its origin cannot be confirmed, delete this file and use a fresh copy from a trusted source. Get a fresh copy from the developer's official site or an official app store.

  4. Recovery step 04

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

Safety FAQ

Direct answers grounded in the saved verdict and evidence in this report.

9 evidence-based answers
Is paperline.exe safe, or is it malware?
Evidence-based answer
paperline.exe is suspicious — treat it as unsafe until you're sure. 2 of 75 antivirus engines flag it; that detection signal contributes to the cautious verdict. Don't run it unless you fully trust where it came from. Get a fresh copy from the developer's official site or an official app store.
What is paperline.exe?
Evidence-based answer
paperline.exe is a Windows executable program, about 7.5 MB. 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 paperline.exe?
Evidence-based answer
2 of 75 antivirus engines flagged paperline.exe, 2 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.
What should I do if I already ran paperline.exe?
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 paperline.exe?
Evidence-based answer
To remove paperline.exe: 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) Delete this file from the device, then empty the Recycle Bin or Trash. 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 paperline.exe?
Evidence-based answer
paperline.exe is classified as adware or a potentially unwanted program (PUA) — not always destructive, but it bundles ads, trackers, or unwanted changes you didn't ask for. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
Is paperline.exe digitally signed?
Evidence-based answer
Yes — paperline.exe carries a valid digital signature from Guangzhou Guoying Communication Technology Co., which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
What is the SHA-256 hash of paperline.exe?
Evidence-based answer
The SHA-256 hash of paperline.exe is 7f1db334fd3302cf98dd4afddf6f90e98e2a496fe7e86bf1832b89d02f3d73c3, and its MD5 is d62d4b7811e37ce789b40ff9343e3458. 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 paperline.exe?
Evidence-based answer
This report reflects the scan run on August 30, 2026. Because a file's hash never changes, the identity of paperline.exe 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.
