How to uninstall PortalFlow app/extension from Mac (Virus removal guide)

What is PortalFlow

PortalFlow is an application that behaves like adware. Adware is a term that originates from ‘ad supported’ software. Most often, ‘adware software’ is considered by many to be synonymous with ‘malicious software’. Its purpose is to make revenue for its owner by showing ads to a user while the user is browsing the Net. The PortalFlow app can display unwanted advertisements, modify web-browser settings, download and install malicious browser add-ons.

The worst is, the PortalFlow adware has the ability to gather and transmit sensitive information without your knowledge. It can be used to track information about webpages visited, browser and system information, and your machine IP address.

How does PortalFlow get on your computer

Adware may be spread with the help of trojan horses and other forms of malware, but most often, adware comes along with some free software. Many makers of freeware include optional apps in their setup files. Sometimes it is possible to avoid the installation of any adware software: carefully read the Terms of Use and the Software license, choose only Manual, Custom or Advanced installation method, disable all checkboxes before clicking Install or Next button while installing new freeware.
