Safe
A small 64-bit Windows driver (viruz.sys) with an invalid signature, flagged malicious by only 2 out of 76 engines including Bkav and McAfee, while top engines like BitDefender and Kaspersky see nothing wrong.
ce5b7aad9b51a3df9b…462f6333a7The reasoning behind this verdict
The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.
The file presents as a 6904-byte Win32 executable disguised as a .sys driver, first seen in early 2025, with PE tags showing it's 64-bit, has an overlay, and an invalid signature. Our antivirus network ran 76 scans: just 2 malicious hits from Bkav's AI generic detection and McAfee's hash-based alert, while tier-1 engines like BitDefender, Kaspersky, ESET, Avast, and others report it undetected. This low detection count (2/76) points to a likely false positive, especially with no consensus on a specific threat family. If run, it might attempt generic malicious behavior due to the detections, but the disagreement suggests it's probably safe. Quarantine or delete it to be cautious.
- 70 out of 76 engines report undetected, including all tier-1 like BitDefender, Kaspersky, ESET.
- No popular threat labels or named families from our analysis.
- No suspicious or PUA detections.
- Small file size consistent with some legit drivers.
- Invalid digital signature on a .sys driver file, which drivers shouldn't have.
- Suspicious name 'viruz.sys' evoking 'virus'.
- Bkav detects it as W64.AIDetectMalware (generic AI-based malware alert).
- McAfeeD flags it via hash (ti!CE5B7AAD9B51), indicating behavioral suspicion.
- PE overlay data, often used to hide malicious payloads.
- Recently first seen (2025), low reputation.
Immediately delete or quarantine viruz.sys and run a full system scan with your antivirus. Avoid running unknown .sys files, as they can load at boot with high privileges.

Safety FAQ
Common questions about viruz.sys, answered from the scan data above.
- viruz.sys appears safe. 74 of 76 antivirus engines report it clean, with only 2 low-confidence detections that read as false positives. As a habit, only run files you downloaded from the official source, since attackers sometimes distribute trojanised copies of legitimate software under the same name.
- viruz.sys is a Windows executable program, about 7 KB. Our analysis found no threat indicators for it. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
- 2 of 76 antivirus engines flagged viruz.sys, 2 of them as outright malicious. A small number of detections can include false positives, so we weigh which engines flagged it and what else the file does, not just the raw count.
- The SHA-256 hash of viruz.sys is ce5b7aad9b51a3df9bbaff5526c1addcb844ed7aeb1fca368d7b41462f6333a7, and its MD5 is b69d358dd6971f7969942576e85cdc7f. 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.
- Based on this scan, yes — viruz.sys shows no threat indicators. 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 while we report it clean, that is most often a false positive, but verify the source before overriding your antivirus.
- This report reflects the scan run on April 20, 2026. Because a file's hash never changes, the identity of viruz.sys 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.
