I successfully downloaded the MATE PowerPC Remix 2017 images from Google Drive and Xenosoft.de with Firefox on Windows 10 today. After that I successfully unpacked them with 7-Zip and then I scanned them with Avast and ClamAV. Downloading and unpacking works without any problems on Windows 10. Avast and ClamAV didn't find any viruses in the MATE PowerPC Remix images.
PLEASE scan your Windows system with a virus scanner and check the other systems. It seems you have some viruses on your Windows system.
