Downloading software is not piracy. Using it is. After all you are entitled to personal backup of your install media. The fact that the backup is distributed and cloud based is irrelevant.
And if it's precracked/modded/etc. then it's definitely not the original, but those who are downloading those would consider the modifications to be value-added.
I have yet to encounter a hard to detect and remove virus coming from a downloaded software from "somewhere else", I'd rather install software coming from the scene than a download portal such as softonic.
