By default, the Windows firewall is installed and enabled, but if for some reason or another he's disabled, simply enable it.
Normally, Windows will notify you automatically.
Note : If you have installed an Internet Security solution, skip this step. Moreover, generally, these solutions offer their own firewall and disable the firewall built into Windows to prevent future problems.
Example on Windows 7 :
To enable the Windows firewall, click on this warning or go to Control Panel.
Now, the firewall is enabled.
If you're running Windows XP, know that its support has stopped and therefore you will no longer receive updates for Windows.
However, if you are on Windows Vista, 7, or a later version of Windows, you should enable Windows Update if it is not already done and install available updates.
To do this, type "Windows Update" in the start menu (if it exists), or go to Control Panel -> System and Security -> Windows Update.
If Windows Update is turned off (hence the red icon), click on "Change settings" (on the left).
Select "Install updates automatically (recommended)" so that updates are automatically downloaded and installed when available.
If you are on a family PC or many people use this computer, select "Allow all users to install updates on this computer".
Then, click "OK".
Then, Windows Update will automatically search for available updates and it's possible that he asks you to download the new software "Windows Update".
Click Install Now and wait
Note : Windows Update will close itself and then reopen.
Finally, Windows Update will search for any available updates.
This process can take time.
Finally, future updates will be installed automatically in the background. No need to go back to Windows Update every x days.
To protect itself from security vulnerabilities present in programs that you use, you should always update them.
Update your programs allows you to :
For this, you have 3 options :
Most known programs offer an integrated automatic updates feature in the installed program.
It periodically checks (the time varies depending on the program) if an update exists on their official website.
Among the known programs that has an updates system, we quote :
If your program does not offer a system to update the program automatically, it will go to the official website of the program.
To do this, look for the program name in Google and never click on ads. At the risk of going on a malicious site instead of the official site.
Download program on its official website and install it over the old one. Generally, there is no need to uninstall the old version of the program unless it is being requested.
The notification of available updates for your programs is interesting, but be careful to not fall into traps created by hackers.
Reliable programs exist to do this stuff, but hackers may also offer you this kind of program to give you infected versions of your programs instead of giving you the original files.
For these types of programs, we recommend these programs :
For plugins, you have 2 options :
For plugins, simply download the latest version of the plugin on their official website :
The Mozilla Firefox web browser is the only one to offer a check of updates for your plugins.
To do this, go to the Firefox menu -> Modules, and click on the "Plugins" tab.
Mozilla Firefox will display the list of plugins installed on your computer and used by Firefox.
Click the link "Check to see if your plugins are up to date" at the top of the list.
You will be redirected to a page that will show you :
As you can see on the bottom left of the window, when we fly over the button "Update", Mozilla will redirect us to the download page for the plugin on the official website of the author.
In this case, the download page of Adobe Reader created by Adobe (it makes sense).
Note : Internet Explorer and Google Chrome doesn't offer this type of system.
