Why we think so
0 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
This setup file is a Kaspersky Anti-Virus 21.3 installer carrying a valid signature from AO Kaspersky Lab. None of the 71 antivirus engines that checked it flagged it, and it has been submitted by 1,285 different sources since 2024. One sandbox run returned a malicious result while another returned clean, a pattern typical of security-product installers.
None of the 71 antivirus engines that checked it flagged the file, including all 18 major antivirus engines that reported on it. The signature from AO Kaspersky Lab verifies and matches a curated trusted publisher. In the sandbox runs the installer fetched Kaspersky product indexes and license texts from Kaspersky's own servers and wrote Kaspersky setup files and registry keys. One run returned malicious and another returned clean, but no process injection target or credential access was recorded, and the 26 contacted hosts we checked carry no malicious or suspicious reputation. Its long history and broad distribution are consistent with an official vendor installer.
What We Detected
A signed Windows installer for Kaspersky Anti-Virus 21.3.10.391. The signature from AO Kaspersky Lab is valid, and none of the 71 antivirus engines that checked it flagged the file. Community YARA matches were generic anti-debug and certificate rules only.
Threat Behavior
The sandbox runs show the installer downloading product indexes, database lists and license agreements from Kaspersky update servers, checking certificate status with DigiCert, and writing setup resources and Kaspersky registry keys. One run returned malicious while another returned clean; no injection into another process and no credential-store access was recorded. The 26 contacted hosts we checked have no malicious or suspicious reputation, and dropped files that matched known-software references were clean.
What To Do Now
The file matches a legitimate Kaspersky installer. Download installers from the vendor's official site where possible, and keep your existing protection enabled during installation.
Where this verdict could be wrong1 caveat
- One sandbox run returned a malicious result, though another run returned clean and no injected process or credential-store access was recorded.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Valid digital signature from AO Kaspersky Lab, a trusted security vendor
- None of the 71 antivirus engines that checked it flagged the file
- Seen by 1,285 different submitters over about two years
- Network activity went to Kaspersky update servers, with no malicious or suspicious host reputation among the 26 hosts checked
- Known-software reference entries confirm several dropped files as clean

VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
EvidenceT1055 (sandbox MITRE mapping)VirusTotal's sandbox summary maps this run to MITRE T1003 (OS Credential Dumping), but no process targeting LSASS or another credential store was recorded. VirusTotal maps T1003 on clean files more often than on detected ones, so the mapping alone is not evidence of credential theft.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
