The Windows software landscape is an endless field of malware/adware/spyware.
If it's not open source and open licensed, et cetera... with the source posted online... I feel like it's a dangerous gamble to install it.
Even software from "reputable" and "professional" companies is sometimes suspect. :/
I was away from Windows for nearly a decade... I'd forgotten it was like this. All the old memories are returning, however. :/
