What is Trojan.ciusky.gen.13

Trojan.ciusky.gen.13 is likely a false positive detected by anti-virus program Bitdefender. It appears that Bitdefender is flagging down Windows 10 Cumulative Update KB4574727 as Trojan.ciusky.gen.13, which prevents the update from installing. Multiple users have reported that when they launch the recently released update, Bitdefender blocks it and shows the alert about Trojan.ciusky.gen.13 being detected.


Bitdefender shows the following (or similar) alert when detecting Cumulative Update KB4574727 as Trojan.ciusky.gen.13:

“The file DeviceHarddiskVolume3WindowsSoftwareDistributionDownload21b4073b65a625a58c006858ea0a97dWindows10.0-KB4574727-x64.cab is infected with Trojan.Ciusky.Gen.13. The threat has been successfully blocked, your device is safe.”

More than likely, this is a false positive and nothing to worry about. And since the issue seems to be with Bitdefender, you’ll likely need to wait for the anti-virus program to be updated. Until then, whenever you try to install the update, it will get flagged as Trojan.ciusky.gen.13.

Do you need to delete Trojan.ciusky.gen.13?

Since it is a false positive, there is no need to delete Trojan.ciusky.gen.13. False positives are more common that you would think. Anti-virus programs may detect files that exhibit behaviour similar to that of malware when the file itself is completely safe. In other cases, anti-virus programs simply clash with other programs for whatever reason, resulting in a false positive detection. False positives can be tricky because it’s difficult to determine whether it is a genuine malware detection or a false one. It’s very important to make sure that it is a false detection before allowing the file/program to remain. One of the ways to make sure is to scan the computer with a different but equally reliable anti-virus program. If the other anti-virus program does not detect the issue, it’s likely a false positive. Alternatively, you could upload the detected file onto VirusTotal to see which, if any, anti-virus programs detect it as a threat.
