Thread: How to avoid other users from uninstalling avast?

In my macbook pro I installed Mac OS X.I have installed avast antivirus on my PC. My PC is used by number of people. I want to prevent them by uninstalling avast from my PC. Can anybody tell me how to prevent other users from uninstalling avast? Please help me.

You have to lock your Mac so that nobody can access your PC and nobody can uninstall avast from your PC. You can lock your PC in the following manners.

1. First go to the Apple menu-> now select System Preferences.

2. Now select Security.

3. Now checked the box for need password to wake this PC from sleep or screen saver.

4. Now by clicking back button go to the main System Preferences window -> now select Desktop & Screen Saver.

5. Click on the Hot Corners. Now set the place and size of the screen saver.

6. Now click on the OK button. If anybody tries to disable the screen saver, he will have to enter your password.
