Do your homework before installing a new plugin or theme and check the vendor’s reputation along with the user feedback. Importantly, go over your plugins and uninstall the ones you are not actively using. As far as WordPress themes go, prioritizing their look and feel while turning a blind eye on their security can be risky business. Stick with trusted repositories such as the WordPress Theme Directory, Themeforest, and TemplateMonster, which thoroughly vet the content they host.
