I've used quite a few Cache plug-ins over the years, and of that list https://wordpress.org/plugins/wp-fastest-cache/ is the one I go back to more than the others.
This is another good one https://wordpress.org/plugins/hummingbird-performance/, and combine that with https://wordpress.org/plugins/wp-smushit/.
I can't guarantee these will fix all your issues, but you should see a tangible improvement.

Bin the you tube thing, dump everything from google, stop using a page builder.
There is a whole load of code being loaded that you don't need. No idea who these developers were but they stole your money.
But that's not the main issue. The main problem is the random and untrustworthy content. Are you really the:
"The Best Malware Removal Service in New York"
Where is the proof of this?
Simplfy the whole site and rework the content to meet the need of your clients. This means for example adding calls to action on every page.

I am not a WP guy, so I cannot help you with recommendations there. However, your site loaded in 2.4s for me. That is far from bad. It seems that most of that time is spent generating the webpage. This leads me to believe that it's either a slow server/database or a plugin. 

Hi there, hope you find what you're looking for!

Hey guys, how is everyone, hoping all is fine.
So I've been a Wordpress Web Designer for  a while now but currently now need to look into HMTL designing which is the main reason I am here, see you all in the forums, thanks.
