Is there a program that prevents the installation of "junk" programs?

Question

Software and Internet Services

Actually, the following situation is not uncommon. You set up a computer and OS for a person, you do everything as it should be, then after a couple of months you look - and the computer is dirty: instead of the antivirus that you installed - some kind of avast. Instead of a normal browser - YANDEX WITH ALICE. Search from mail ru. And a bunch of all sorts of optimizers and driver updaters.
Actually, have you come up with any software to deal with such garbage? Except unchecky. It certainly helps to some extent, but not always.

Answer 1

If a person is dumb, no program will help. Just take the money in the second round and clean it up ... remotely, for example
. From my point of view, only the “windows for dummies” book and changing the gasket between the chair and the monitor will help here.
By default, these are not viruses or bad programs, so I don’t think you will find one soft. Moreover, what if a person really wants Avast or Yandex/Mail for himself?
You can think of digging antivirus, we can have such functions there. Kind of child mode. In the same Kaspersky or other Web ...

Answer 2

It is possible through group security policies if Windows.
Well, it's not a matter of sitting under the admin =)

Answer 3

If the person works under the administrator it is useless. Only create a separate account without admin rights, and do not give a password from the admin account, do not disable UAC.
