how to remove this link at upper left corner of my website

Try and find where the code is coming from. Search your theme directory with specific keywords like -follow-button.
However you can hide the section with

a.-follow-button {
    display: none;
}

Actually i am searching files for last 2 day, But i couldn’t find.taking positively your suggestion i believe now i am missing something.but incase the source file not found like past 2 days, do you have any idea, where should i look,Possibility is header.php, While searching cpanel i found there are 4-5 header.php, it may because of my theme which suports 4-5 different header layouts.I will let you know if i find anything.So point is please suggest me at which file possibilities are high.Sorry if english is wrong.I am not good in this.Thanks for replying

additionally for a temporary solution i did something and got this follow button, I restored my website from backup, but i know at the day when i post anything the situation would become same so i have to remove this either this is a not working link or a working follow button,I am updating what i am doing because i guess it might help someone in same situation.
