Redirect issue

I get an email from google console once i added my site phillyfitdog.com
here is the message of the email.

Following are one or more example URLs where we found pages that have been compromised. Review them to gain a better sense of where this hacked content appears. The list is not exhaustive.

https://phillyfitdog.com/index.php?main_page=index&cPath=1_
https://phillyfitdog.com/index.php?main_page=index&cPath=1_2_
https://phillyfitdog.com/index.php?main_page=index&cPath=1_2_3

So i did a reinstall of wordpress and still not fixed according to google fetch.
I checked my htaccess file and this is whats in it….

RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} (google|yahoo|msn|aol|bing) [OR]
RewriteCond %{HTTP_REFERER} (google|yahoo|msn|aol|bing)
RewriteRule ^([^/]*)/$ /wp-global-it.php?p=$1 [L]
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^([0-9]+)\/([^\d\/]+)([0-9]+).*_.*..*$ ?$2$1=$3&%{QUERY_STRING}[L]
RewriteRule ^([0-9]+)\/([^\d\/]+)([0-9]+)-.*[0-9]+..*$ ?$2$1=$3&%{QUERY_STRING}[L]
RewriteRule ^([0-9]+)\/([^\d\/]+)([0-9]+)..*$ ?$2$1=$3&%{QUERY_STRING}[L]
RewriteRule ^([0-9]+)\/([^\d\/]+)([0-9]+).*[0-9]+..*$ ?$2$1=$3&%{QUERY_STRING}[L]
RewriteRule ^([^\d\/]+)\/([0-9]+)\/[0-9]+G.*UHL[0-9]+.*\/([0-9]+)-W.*[0-9]+.*NK.*$ ?$1$2=$7&%{QUERY_STRING}[L]
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

I took a look at another one of my sites that is not redirected and the htaccess file looked like this…..

# Use PHP5.4 as default
AddHandler application/x-httpd-php54 .php

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Totally different. Can anyone help on how to clean up this issue?
