Is CCleaner 7 PRO Activation.zip safe?
Only Elastic flagged this encrypted activation archive, but its embedded executable, very limited history, and absent runtime evidence warrant caution.
Only 1 of 74 engines detected the archive, while all 17 reporting tier-1 engines remained silent and no external intelligence corroborated the detection. However, this is a two-day-old encrypted activation archive containing an executable, and no completed runtime analysis is available, so it should not be opened on a normal system.

Before opening or extracting
Do not open or extract it until the source can be verified independently.
If you already opened or extracted it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the original trusted source and verify its exact hash when possible.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Only 1 of 74 engines detected the archive, while all 17 reporting tier-1 engines remained silent and no external intelligence corroborated the detection. However, this is a two-day-old encrypted activation archive containing an executable, and no completed runtime analysis is available, so it should not be opened on a normal system.
Elastic alone flagged the file, without naming a malware family, while all reporting tier-1 engines were undetected. That isolated result could be a false positive, and the external intelligence checks supplied no corroborating match. Nevertheless, the ZIP is encrypted and contains an executable, which can prevent engines from examining the payload fully. Its activation-themed name and extremely limited two-day history add practical risk, although the filename alone does not establish malware. No completed sandbox observation or complete contacted-host reputation result is available to resolve these mixed signals.
What We Detected
Elastic was the sole detector among 74 engines and returned a generic high-confidence malicious result. All 17 reporting tier-1 engines, including Microsoft, Kaspersky, BitDefender, ESET-NOD32, and Avast, were undetected, and no named family consensus emerged. Researcher-curated checks supplied no matching YARA rules or known-malware record.
Threat Behavior
The sample is an encrypted ZIP containing a Windows executable. Encryption can obstruct inspection of the embedded file, so the low detection count is not conclusive. No completed sandbox run is available, and the contacted-host reputation cross-check was not completed or saved; therefore, there is no runtime or complete network-reputation evidence to characterize its behavior.
What To Do Now
Do not extract or execute this activation package on a production or personal system. Keep endpoint protection enabled, obtain CCleaner only through its official distribution channel, and use a legitimate license rather than third-party activation archives.
Where this verdict could be wrong2 caveats
- Elastic, a tier-2 engine, reports "malicious (high confidence)," although no named family or independent engine corroboration is present.
- The encrypted archive may have prevented complete inspection of its embedded executable, limiting the reassurance provided by other engines.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 1/74 engines detected the archive
- engines.tier1Malicious=0, with 17 reporting tier-1 engines undetected
- No tier-1 family consensus
- No MalwareBazaar, CIRCL, or YARAify hit
- Encrypted ZIP may conceal its embedded executable from complete inspection
- Activation-themed archive from an unofficial or unverified source
- Only two submissions from two sources over a two-day history
- No completed runtime observation
- No complete contacted-host reputation result
Delete the archive unless its provenance can be independently verified, and obtain the software and license through the official vendor. Keep antivirus and endpoint protection enabled.
