What is supposedly a portal for free maps and driving directions is actually a browser hijacker that will attempt to commandeer a user’s homepage. After installing Directions Tab, this browser hijacker will change browser search to https://directionstab.com and will redirect you to malicious websites to get money from you or infect your computer further. It may also prevent you from changing your settings back.
Directions Tab is usually installed through bundled software without you knowing. Remove it immediately.
