macOS remove lkysearch virus from chrome
Ok, so this is how I removed the malware.

1) sudo rm -rf /Library/LaunchDaemons/com.ElementarySignalSearchDaemon.plist 

the content of plist was, 

cat  /Library/LaunchDaemons/com.ElementarySignalSearchDaemon.plist 
&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"&gt;
&lt;plist version="1.0"&gt;
    &lt;dict&gt;
        &lt;key&gt;Label&lt;/key&gt;
        &lt;string&gt;com.ElementarySignalSearchDaemon&lt;/string&gt;
        &lt;key&gt;ProgramArguments&lt;/key&gt;
        &lt;array&gt;
            &lt;string&gt;/Library/Application Support/com.ElementarySignalSearchDaemon/ElementarySignalSearch&lt;/string&gt;
            &lt;string&gt;r&lt;/string&gt;
        &lt;/array&gt;
        &lt;key&gt;RunAtLoad&lt;/key&gt;
        &lt;true /&gt;
        &lt;key&gt;StartInterval&lt;/key&gt;
        &lt;integer&gt;14400&lt;/integer&gt;
    &lt;/dict&gt;
&lt;/plist&gt;


2) sudo rm -rf /Library/Application\ Support/com.ElementarySignalSearchDaemon/

3) restarting the chrome did not work, so edited the plist file and removed the occurrence of links in that file,

This is because chrome://policy had Mandatory level.

sudo vi /Library/Managed\ Preferences/prayagupd/com.google.Chrome.plist 


4) remove suspicious profiles,
