Big problem with downloads


Apr 12, 2015
Hi guys. I have a seriously problem.

When I download any compressed file in zip format, when I open it, it show me another zip which in turn contains a .exe with malware (, for example). All files in zip format that I download (example: when download zip repository in github/crosire/reshade). This happens in all my browsers (Edge, Chrome, Firefox, Vivaldi).

I scanned with windows removal tool, Malwarebytes and Windows Defender from the SO. I have also scanned all system with several rescue CD before the start of windows (Karspersky, Avira), nothing. Only detect false positives in game cracks files and little else.. I do not know what else to do.

Any ideas, please?
