Achanges your home page and redirects you to other websites.

A Browser hijacker changes your home page and redirects you to other websites.

Further explanationWhat is Chumsearch?

This is a type of malware known as a browser hijacker. In this case, this redirects your browser's homepage to Chumsearch, a web page that is designed to look like the Google homepage but is very different. Like other browser hijackers, there are many reasons why Chumsearch is not accepted on your computer. It collects data about your web browsing activity and passes it back to the server; it provides search results that take you to sites that can harm your computer, and it displays advertisements that are forms of adware.

How to delete Chumsearch from your Mac

Step 1: Delete the Chumsearch profile

Click on the Apple menu and select System Preferences. Look for the panel in the bottom row called Profiles. If it's there, click there and look for a profile called AdminPrefs. If you can see AdminPrefs, click the lock and type your admin username and password. Click on the AdminPrefs profile and click the ‘-‘ button at the bottom left of the window.

Step 2: Check your Login Item

Browser hijackers, like other malware, want to launch themselves as soon as you turn on your Mac so they enter your Login Item. Here's how to get rid of Chumsearch from your Login Item.

Go to System Preferences and click on the Users & Groups panel. Open the lock by clicking on the lock and then typing in your username and password. Select the Incoming Items tab. Look for entry items that look like Chumsearch or other malware. If you find something, click on it then click the ‘-‘ button at the bottom of the window to get rid of it.

Step 3: Remove Chumsearch from your browser

Safari:

Launch Safari. Click on the Safari menu and select Preferences. Click on the Search tab and select the search engine that you want to use. Select the General tab and set the Homepage to the homepage of your choice and the options above it for your preferences from the options on the menu.

Chrome:

Launch Chrome. Click the Settings menu icon on the left side of the window (it looks like three horizontal lines) or type "chrome: // settings" into the address bar. Select "when starting" and check the button next to "Open a specific page or set of pages." Click the other icon (it looks like three dots are piled on top of each other). Select "edit" and type or paste the address of the startup page of your choice into the text box. Press Save. Click on the Settings icon again and select Search Engine. Select "manage search engines" and press the "other" button next to Chumsearch and select "delete from the list." Click on the dropdown menu next to the "Search engine used in the address bar" and select the search engine you want to use.
