Our hosting, security software and processes are designed to ensure this doesn’t happen. However, it is still possible but rare. For example, if a software vulnerability isn’t patched quickly enough by a third party software developer then your site is vulnerable. This has only happened once to us in the last ten years and was resolved in less than an hour. Both our maintenance plans include malware removal and a website back up restore. If your website needs further assistance and a Sucuri clean and fix this would be chargeable. This has not yet happened with our websites but we have seen serious hacks with websites where they have not been maintained or are using out of date software.
