Wi-Fi Inspector or Smart Scan in Avast Antivirus may have detected that your PC is vulnerable or has been subjected to the DoublePulsar attack which is used by WannaCry ransomware and other malicious threats. This means that your PC is running an outdated version of the Windows File and Printer Sharing service (SMB), which contains a vulnerability known as EternalBlue. The vulnerability can be resolved by installing the MS17-010 security update.
Installing the MS17-010 security update
To install the MS17-010 security update, follow the steps according to your version of Windows.
Before installing the MS17-010 security update, disconnect from the network and restart your PC. If the Double Pulsar exploit is already present, attempting these resolution steps without disconnecting from the network and restarting your PC could prevent your PC from starting.
