Because of former problems with spyware I am very focused on security. Due to that I focuses on the details in my firewall, Comodo.
A few days ago I wanted to make another control of which files are registered as Trusted files in Comodo's section Defense +. A database of "safe executable s". After hundreds of programs installed I have got 60 files registered as safe. Until i installed VLC. Then the number of files has almost doubled! The installer of VLC added further 48! (No other software or co. has registered more than four lines on that list). Everything mixed. Due to that I had to spend a long time deleting... Now finally VLC has been removed and my important database over safe applications are possible to use/understand/read once again.
So if you are conserned about security, use Comodo Firewall, and want to keep control by yourself; don't install VLC at this stage! From now on Media Player Classic has taken over.
