I got mine to work by removing this line of code in the .htaccess:
RewriteRule ^exit store/wp-login.php?action=logout&_wpnonce=2f3538a9ec&hide_out_key=BkkO5034 [L]
For some reason it would not let me log out but once I removed this line it works :-)!! Also I have not encountered the virus URL but I will scan the DB/plugin folder to make sure.
Another thing is the “&” for some reason was written in HTML in the htaccess (?hide_in_key=hqa60C7–>&<—redirect_to=https://patrickmediagroup.com/store/wp-admin/_)
So I had to change it and it fixed my other redirect issue. Hope this helps!
