I just read the following news about how connected USB devices can act as keyboards or network cards, etc. and so for example input what they like or change sites to scam sites. http://www.bbc.com/news/technology-28701124
If the operating system initially blocked USB devices when connected until a notification stating what it does is confirmed, then it would be less of a worry. Is there a way to do this? (Windows 7 or 8)
