duplicate of [/questions/1433030] thread. I‘m somewhat uncertain: I downloaded the Firefox Installer from (I believe) Mozilla.org via Edge. When I tried to Upload the file to VirusTotal I got errors first and it only worked after restarting the laptop. The file hadn‘t been analyzed so far (which surprised me), 1 out of 72 scanners claimed to have found a Trojan but what bothered me more was that according to VirusTotal the file was compiled in 2018 with Microsoft Visual C/C++ 12.00.8168. It was also somewhat smaller than the last Installer I downloaded (342kb vs. 390kb), although both should be version 18.05. So I‘m a little concerned if the downloaded file is legitimate?
