WP_Login corrupted. Is there a virus?

I am unable to login to my wordpress account.

I see the the 2 errors on my login page (https://stalefresh.com/wp-login.php)

Warning: Cannot modify header information – headers already sent by (output started at /home/myaccount/public_html/wp-login.php:1) in /home/harami/public_html/wp-login.php on line 266

Warning: Cannot modify header information – headers already sent by (output started at /home/myaccount/public_html/wp-login.php:1) in /home/harami/public_html/wp-login.php on line 278

I checked the code on these lines and I don’t see any spacing issues.

Also, on https://stalefresh.com/wp-login.php page I first get a malware message warning. I checked with my web host and he confirmed he ran a virus scan but there is nothing. I also checked with google webmasters and they confirmed there is no virus. I feel there is some bad code etc out there. I haven’t blogged in a few months and something went wrong since then.

Please advice.

Thanks!
