<SOLVED> For security reason Mono should be uninstalled

[KIMW]

Here https://sites.google.com/site/easylinux ... t/security I read that sometimes Mono is installed automatically whenever an application needs the Mono infrastructure (like media player Banshee and notes app Tomboy) and for security reason it should be uninstalled with: sudo apt-get remove mono-runtime-common. So I run that command and although I don't have Banshee or Tomboy I actually found Mono was installed. Should I really uninstall it?

Everything written in https://sites.google.com/site/easylinuxtipsproject is only personal opinion of author.
Mono is an open source implementation of Microsoft's .NET Framework based on the ECMA standards for C# and the Common Language Runtime.
Everyone can learn it's source code and decide by himself is it vulnerable or not.

That is a matter of opinion. You will probably not find a final answer.
As you've seen, Pjotr (whose page you're linking to) considers Mono to be an unnecessary risk. Others feel that some risk is present, but too small to worry about. I tried to find more factual information, but have not found anything so far and I'll be interested to see if others can come up with anything substantial.

In principle every software is attackable, especially complex runtime libraries. A software, which is not installed, cannot get attacked (obviously). If you have no need for mono, you can safely remove it. In case you want to install a mono-dependent software at a later time mono will get installed again as a dependency. Site effect of removing mono: You save the needed bandwidth for updates, which have no practical sense, if do not use it.

I've removed mono from my system. If you don't use any apps that require mono, there's no reason to keep it. But like Moem says, it's all a matter of opinion (whether to keep it or not).

For a newbie like me it's difficult to say if I need it or not...Since it was already installed perhaps I should leave, because if I remove it it might create troubles, don't you think so?

Otherwise I downloaded and installed Teamviewer from https://www.teamviewer.com/en/download/linux/ BUT I discovered that TeamViewer has also installed somehow a version WINE which I read (on that same page written by Pjotr) is not a good thing. What do you think about that?

As my name keeps popping up, I might as well add my two cents as well.

The Wine developers themselves clearly state that Wine is "malware-compatible":

Note the load of misery that you're taking on when installing Wine, up to and including the need for antivirus....

Except Banshee and Tomboy there are no other Mono-dependent programs installed by default. If you don't need them, you don't need Mono. If you later want to install a Mono-dependent software and Mono has been removed, it will get installed again. Removing Mono is no one-way-ticket. Linux or Mint themselves don't need it.

Teamviewer and wind is a quite different story and deserves a separate thread.

Strange, I don't have have Banshee and Tomboy.
I ran: "sudo apt-get remove mono-runtime-common", and got:

The following packages were automatically installed and are no longer required:
fonts-liberation libmyth-0.27-0 libmyth-python libva-glx1 libxml-libxml-perl

libxml-sax-perl libxml-simple-perl libxml-xpath-perl pwgen python-imdbpy

Use 'apt-get autoremove' to remove them.
