Where this verdict could be wrong3 caveats
  • triggeredHeuristics.MalwareTips.Synth.DirectIpC2 fired (medium severity) citing 7 contactedIps with no domains, but contactedUrls show avcdn.net domains — possible heuristic imprecision on CDN resolution.
  • signerStats.totalSamples=1 too low for autoTrusted=true, though trustedPublisher.matched overrides.
  • filenameAnalysis all false; 'icarus_sfx.exe' unclassified but matches observed piriform-ccl drops.

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

  1. Recovery step 01

    Run it only when it came from the developer's official site or another source you independently trust.

  2. Recovery step 02

7 evidence-based answers
Is icarus_sfx.exe safe?
Evidence-based answer
icarus_sfx.exe appears safe. 1 of 76 antivirus engines flagged it; the 1 detection were treated as non-decisive after the wider evidence was weighed. It carries a verified digital signature from Gen Digital Inc.. Run it only when it came from the developer's official site or another source you independently trust.
What is icarus_sfx.exe?
Evidence-based answer
icarus_sfx.exe is a Windows executable program, about 1.7 MB. Our analysis did not identify a verdict-driving threat signal. It carries a verified digital signature from Gen Digital Inc.. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
How many antivirus engines detected icarus_sfx.exe?
Evidence-based answer
1 of 76 antivirus engines flagged icarus_sfx.exe, 1 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.
Is icarus_sfx.exe digitally signed?
Evidence-based answer
Yes — icarus_sfx.exe carries a valid digital signature from Gen Digital Inc., 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 icarus_sfx.exe?
Evidence-based answer
The SHA-256 hash of icarus_sfx.exe is f865d2879b890459952a1e6dd1d881e89d84325b3bf8035ba63ae3116115dd16, and its MD5 is a89c041f764df30a9de18e012075bea6. 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.
Is it safe to run icarus_sfx.exe?
Evidence-based answer
Based on the recorded evidence, icarus_sfx.exe has a low observed risk and is properly signed. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it, verify the source and the exact hash before overriding the warning.
How up to date is this analysis of icarus_sfx.exe?
Evidence-based answer
This report reflects the scan run on April 22, 2026. Because a file's hash never changes, the identity of icarus_sfx.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.
