It has already been stated hundred times like here https://robert.ocallahan.org/2017/01/disable-your-antivirus-software-except.html but people are still getting fooled by the sponsored articles and "tests" in IT magazines to install this bloody potato that's responsible for most of the Windows issues and security incidents.
On the other hand to download and execute an executable from a blackbox is a bad practice either. So please, provide the full offline installer as it was before.
