Just a heads up that FossHub was hacked. Reports are coming in that downloads of ClassicShell and Audacity were affected (possibly more). Both ClassicShell and Audacity use FossHub as their official download site, so if you went to Audacity's site and selected to download the local version of Audacity, you might be affected. The malware in question wipes your PC's master boot record rendering the PC unbootable once you reboot.
