Warning on uninstall hack

[thorfrog]

Last night I uninstalled Total War-MiddleAges, and a deleted some minor files. When I went over to play SEIV all of my games were either uninstalled or partially deleted. Last night I spent my time reinstalling my games. But I lost alot. Now only my games folder was effected by this. No other damage occured to my system. Has anyone ever heard of such a thing? I suspect a few things: the uninstall for Total War-MA has a bug that will uninstall all programs in the same folder, I was hacked, virus (I doubt it), or user error (doubt also). Let me know if anyone else has experience this.
