[QUOTE="Andy Ful, post: 823633, member: 32260"] That is also my observation. Windows Defender detection of never seen samples strongly depends on the cloud (except ASR rules and Controlled Folder Access). Furthermore, the best protection (BAFS) is available only when files are recognized as downloaded from the Internet. People who use FAT32 sources (flash drives, USB disks) for sharing files with other people are not so well protected, except when they will upload the files to OneDrive or execute the files directly from the USB source (protected by very aggressive ASR rule). If so, then the file downloaded to the hard disk from OneDrive will be automatically checked by BAFS. It is also crucial to use the Windows built-in ZIP archiver or Bandzip archiver, which can preserve MOTW after decompressing files from archives (downloaded from the Internet). With the above precautions, WD + ConfigureDefender can achieve similar protection for fresh samples, as any commercial AV on default settings. This protection can be even stronger when applying SysHardener restrictions or maximize the protection with Hard_Configurator. [/QUOTE]
