This involves Firefox Portable 77.0.1. I've used the portable version for a long time and never had any problems with it or any software from this website.
Norton AntiVirus reports the download safe. But after I install it on my local drive, and Norton runs a scan, it reports PUA.Gamevance in the registry (approximately 40 registry entries). That is amazing since the portable version doesn't write to the registry. Or does it?
I then uninstalled Firefox, cleaned the malware (I ran Norton AntiVirus, Norton Power Eraser, and Malwrebytes AntiRootkit). I rescanned. All was clean. I then downloaded a new copy of 77.0.1 from this website. Again, Norton was OK with the downloaded file. I reinstalled Firefox and then ran another Norton scan. Now, I find the same registry entries for PUA.Gamevance. I did nothing else between the two installations so nothing else can account for this.
Any suggestions or comments? I can't figure out why or how the downloaded file installed PUA.Gamevance, and I don't know if I can trust Firefox Portable.
Thx
