AVAST SecureLine and AVG Secure VPN can protect you from Man-in-the-Middle Attack

A man in the middle (MITM) attack is a general term for when a perpetrator positions himself in a conversation between a user and an application—either to eavesdrop or to impersonate one of the parties, making it appear as if a normal exchange of information is underway.

The goal of an attack is to steal personal information, such as login credentials, account details and credit card numbers. Targets are typically the users of financial applications, SaaS businesses, e-commerce sites and other websites where logging in is required.

Information obtained during an attack could be used for many purposes, including identity theft, unapproved fund transfers or an illicit password change.

Additionally, it can be used to gain a foothold inside a secured perimeter during the infiltration stage of an advanced persistent threat (APT) assault.
Broadly speaking, a MITM attack is the equivalent of a mailman opening your bank statement, writing down your account details and then resealing the envelope and delivering it to your door.
