@ieuanoh: Sorry, but you’re using Visual Composer, a premium/paid plugin. It’s best to go to the support site where you bought the plugin for help with customizations and issues. You paid for support when you bought the products, so you should contact the developers. These forums are for plugins available at wordpress.org/plugins/. See http://codex.wordpress.org/Forum_Welcome#Commercial_Products

It’s not a huge deal to convert a static site design to a WordPress theme; see https://codex.wordpress.org/Theme_Development

But you’ve got a curious mix: your page source says WP Visual Composer is being used. So maybe someone exported PHP from VC? And your slider on the home page is Revolution Slider, well known to have security holes in earlier versions. And the account and payment code will need to be adapted to WordPress or you’ll need to convert to WordPress functions for those.

@justinemcinerney: you are wasting everyone’s time by posting multiple copies of the same question in old, unrelated threads. Stop that.

I see javascript errors in the console that point to a theme broken by the jQuery 1.12 update. Read https://wordpress.org/support/topic/read-this-first-wordpress-45-master-list?replies=7 and update your theme.

@bryan Valentino: malinrebecka is not asking about line heights in CSS; he/she is asking about line breaks.

@malinrebecka: try <b>&nbsp;</b> That’s a non-breaking space in between bold tags; this fools the WP editor into thinking there is text and adding paragraph breaks around it, and so you get a paragraph break.

Or, try https://wordpress.org/plugins/spacer/

I see several javascript errors in the console, including one that is a 404 for a javascript, and one that is a possible conflict with jQueryMigrate.

But you’re using WP-Clear, a premium/paid theme that is not supported in these forums. It’s best to go to the support site where you bought the theme for help with customizations and issues. You paid for support when you bought the theme, so you should contact the people who sold you the theme.

@luke: why are you responding to months-old threads, like this one?

How are these things created? What vulnrability are they exploiting?

Much of it depends on the host; some are less secure than others. You need to parse the server logs to find the exploits.

How can I stop this?

Find a good host. And read Hardening WordPress – WordPress Codex and Brute Force Attacks – WordPress Codex
