How to uninstall ExtendedMode app/extension from Mac

What is ExtendedMode

ExtendedMode is an adware program. Adware is a form of malware that presents unwanted advertisements to the user of a computer. The advertisements produced by adware software are sometimes in the form of a in-text link, pop-up or sometimes in an unclosable window. ExtendedMode can take over your web-browser and force you to use an unwanted web-page as your default search engine, startpage and new tab.

Another reason why you need to get rid of adware is its online data-tracking activity. Adware software can collect confidential info, including:

• IP addresses;
• URLs visited;
• search queries/terms;
• clicks on links and ads;
• web browser version information.

If you would like to remove ExtendedMode and free your internet browser of unwanted advertisements and are unable to do so, you can follow the instructions below to detect and get rid of adware software and any other malicious software for free.
