deeveedee Posted March 5, 2025 Share Posted March 5, 2025 Thank you as always, @miliuco. Have you noticed that only the VirtualSMC.kext source code is available for download (not the Release or Debug kexts)? 1 Link to comment https://www.insanelymac.com/forum/topic/360743-how-to-opencore-103-104-differences/#findComment-2830720 Share on other sites More sharing options...
miliuco Posted March 5, 2025 Author Share Posted March 5, 2025 @deeveedee Yes, I noticed this. I don't know why. I was hesitating to add VirtualSMC to the list. Minimal changes, as I read in your other post, so no need to update for the vast majority of us. 1 Link to comment https://www.insanelymac.com/forum/topic/360743-how-to-opencore-103-104-differences/#findComment-2830728 Share on other sites More sharing options...
deeveedee Posted March 5, 2025 Share Posted March 5, 2025 (edited) I see they're still making updates. EDIT: The Release and Debug kexts for VirtualSMC 1.3.5 are now posted.

deeveedee Posted April 1, 2025 Share Posted April 1, 2025 (edited) Has anyone else seen this Norton Antivirus warning about VirtualSMC.kext? Threat name: MacOS:AMOS-BI [Trj] Severity: 2 Threat type: Trojan File name: VirtualSMC-1.3.5-RELEASE.zip File path: /Users/deeveedee/Downloads/VirtualSMC-1.3.5-RELEASE.zip Process: /System/Volumes/Preboot/Cryptexes/App/System/Applications/Safari.app/Contents/XPCServices/com.apple.Safari.SandboxBroker.xpc/Contents/MacOS/com.apple.Safari.SandboxBroker Detected by: Download Intelligence Status: Threat blocked EDIT: I'm not sure whether this is actually a threat detected in VirtualSMC.kext or something with GoogleAds. See more here. EDIT2: I downloaded a few other Acidanthera kexts and don't see the Norton detected Trojan. It appears that, so far, this Trojan threat is specific to VirtualSMC. I haven't seen this before, but hopeful that this is a false alarm due to the nature of VirtualSMC. EDIT3: I do not see this Trojan when I download VirtualSMC 1.3.4, so this is specific to 1.3.5. EDIT4: It appears to me that the virus is in the .zip file downloaded from Acidanthera. After unzipping the kext, Norton does not detect the Trojan virus in the unzipped (raw) kext.

verdazil Posted April 1, 2025 Share Posted April 1, 2025 @deeveedee, v1.3.4 apparently it's already in the Norton database. The 1.3.5 version is defined as a virus heuristically. Later, it will also be included in the Norton database. 1 Link to comment https://www.insanelymac.com/forum/topic/360743-how-to-opencore-103-104-differences/#findComment-2831260 Share on other sites More sharing options...
deeveedee Posted April 1, 2025 Share Posted April 1, 2025 (edited) @verdazil You are correct. Closed as false positive.
