It has an interleaved 720K format which is not compatible with earlier versions of A-Max and neither can the image be opened in Mini vMac. The disk was created with the final A-Max version 4.x, which I have not been able to find a working copy of. I admit that it's a real possibility that the disk actually carries this virus, but I cannot check it, as it will not mount successfully in emulation, either as a disk in my Amiga or as an image in Mini vMac. However, because it shows 'MacOS' in the malware name, it is perfectly possible that the virus database incorporates both PC and Macintosh signatures. Click the blue (ON) slider next to Enhanced Tracking Protection is ON for this site so that it changes to gray (OFF). ran boot scan and avast detected a general trojan but was unable to remove threat. Click the shield icon to the left of the address bar. disabled system restore on all drives, ran mbam and avast on safe mode. Until this happened, I didn't know that Avast! could detect Mac viruses too. Open any webpage from the domain in your browser window (this is any URL that has at the beginning). Right click on the Avast system tray icon Click on Start Avast Anti Virus Avast anti virus window will pop up and run a memory scan Once memory scan finish. This seemed to suggest that the disk carried an Nvir-B infection, not that the file actually comprised the Nvir-B virus. You can set what areas you want the Boot Time scan to scan (by default it scans all hard disks) - this can be changed by the settings wrench icon of Boot Time Scan.

When scanning one of the A-Max disk images I mentioned, the Avast! program provided the malware name MacOS:Nvir-B and type Virus/Worm (the VPS version was 090520-0, ). Hi, avast UI > Protection > Anti-Virus > Other Scans > Boot Time Scan You then have the option to add specialised definitions.
