MadmanRB, that's also where the browsers & a lot of other software installs itself, I found this out when clean installing the next version of Linux Mint, formatting only the root partition, but not the /home or Swap, just marking these as such.
After 4-5 of these 'clean upgrades', you'd be surprised at all of the garbage left behind from apps (sometimes uninstalled 3-4 versions ago, at times the icons from the last install will be there at boot. Until early this year, had recycled the same /home partition from Mint 12 to Mint 17.1, Once I purchased a larger HDD to hold my VM's, decided to start with a total clean slate, so placed the items I wanted to keep in a folder of one of my external backup drives & nuked the rest.
So I want to protect that partition as much as possible, fortunately I have professional Linux security in ESET for Unices, but still WINE involves IE, something that I don't even want on my Windows installs & will surely not have it on my Linux ones.
Years ago, I did play with WINE a bit & it was OK, but not anything to write home about. More recently, I assisted a member with getting Pipelight installed, not knowing it involved WINE, and afterwards, spent nearly an hour sifting through folders after uninstall & deleting anything WINE related. The native uninstallers aren't as good as performing this from the Terminal.
Yet please don't take me the wrong way, there's some instances where WINE is needed, like for a Microsoft Office install & it used to be that way for Netflix. The only thing about having WINE on the system, it's like having part of Windows on it, this means extra security is needed, be it free (there's a Topic dedicated to Sophos) or a Pro version like I have, though not on every MInt system I have, my license isn't for unlimited devices.
It's a gamble where the user must weigh the benefit & risk of having WINE installed. On my computers, any Windows software in Linux Mint are running in virtual machines & there's no sharing of folders. This is more secure & a better alternative to WINE, if the system has enough power & RAM to run a VM. I have a copy of Windows 10 Pro running in VMware Player on the OS, yet it can't access other folders, ans=d I flip down the Webcam's lid to prevent being spied on. And the main reason it's there are to assist my relatives & a few close friends in need, it may be booted 2 times a month, if that.
The bottom line is, I'm a security freak, while some are comfortable with using WINE, and that's OK be me, it's not my computer, others feels different about the issue. I also uninstall any Torrent software that ships with the OS, as I don't want these apps around me, they're a security risk to use.
Hope this explains my position on the issue.
