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 Vulnerability Scan.

3. The first time you access Vulnerability Scan, you are introduced into the feature. Click START SCAN to continue, and then wait for Bitdefender to check your system for vulnerabilities.
