How to scan your system for vulnerabilities

An important step in protecting your computer against malicious actions and apps is to keep the operating system and the apps you regularly use up to date. Moreover, to prevent unauthorized physical access to your computer, strong passwords that cannot be easily guessed must be configured for each Windows user account and for the Wi-Fi networks you connect to as well. These are system vulnerabilities that can exploited by cyber attacks to gain or perform unauthorized actions on a computer.


Bitdefender automatically checks your system for vulnerabilities and alerts you about them. You should check and fix system vulnerabilities every one or two weeks. 

To manually scan your system for vulnerabilities:

1. Click Protection on the left sidebar of the Bitdefender interface.

2. In the VULNERABILITY pane, click Open.

3. In the Vulnerability Scan tab click Start Scan, then wait for Bitdefender to check your system for vulnerabilities. The detected vulnerabilities are grouped in the three categories:


Operating System Security

Altered system settings that may compromise your device and data, such as not displaying warnings when executed files perform changes on your system without your permission or when MTP devices such as phones or cameras connect and execute different operations without your knowledge.

Critical Windows updates

A list of critical Windows updates that are not installed on your computer is displayed. A system restart may be required to allow Bitdefender finish the installation. Please note that it may take a while to install the updates.

Weak Windows accounts

You can see the list of the Windows user accounts configured on your device and the level of protection their password provides. You can choose between asking the user to change the password at the next login or changing the password yourself immediately. To set a new password for your system, select Change the password now. To create a strong password, we recommend you to use a combination of uppercase and lowercase letters, numbers and special characters (such as #, $ or @).


Browser Security

Change upon your device’s settings that allows the execution of files and programs downloaded via Internet Explorer without an integrity validation, which may lead to your device being compromised.

Application updates

To see information about the app that needs to be updated, click its name from the list. If an app is not up to date, click Download new version to download the latest version.


Network & Credentials

Altered system settings such as automatically connecting to open hotspot networks without your knowledge or not enforcing encryption on the outgoing secure channel traffic.

Wi-Fi networks & routers

To find out more about the wireless network and router you are connected to, click its name from the list. If it is recommended to set a stronger password for your home network, make sure that you follow our instructions, so that you can stay connected without worrying about your privacy. When other recommendations are available, follow the provided instructions to make sure your home network stays safe from the hackers’ prying eyes.
