| Noone mentioned essential mistake which people are making while using their windows machines: they are using Windows logged in as Administrators. This means that all malware is free to install itself anywhere, is free to modify all system settings, disable malware protection software and so on.
Create and use unpriviledged user. Then anyone can click whatever they want, system won't be affected, most of malware will fail simply because it won't get Administrator rights to run itself. |
