What is malware? If you run a website, you're probably haunted by the spectre of malware. The idea that your website could be compromised by people with malicious intent is a horrifying thought.
In this guide, we'll explain what malware is, how it works, how you can remove malware from your website and how to protect your website against it.

What does malware mean?
The word "malware" is a combination of the words malicious and software, and covers any programme or file that is harmful to a computer user.
Malware covers a wide spectrum of things including like:
Viruses: Viruses infect and corrupt files on a computer, making them unusable. They can even delete files. A virus could lead to significant data loss. They're a good reminder as to why you should always backup regularly, and never open files that you aren't sure are safe.
Spyware: Spyware allows hackers to monitor what you do on your computer - including passwords, credit card details and any other sensitive data that you type into websites.
Ransomware: A particularly troublesome piece of malware, especially for business owners, ransomware encrypts your files so you can't access them. The hackers then demand payment to unlock your files. Regular backups will help mitigate the risks of ransomware.
Trojans: Much like the famed Trojan Horse, Trojans pretend to be one thing, but actually allow malware to sneak on to your device. Often they allow hackers to install more malware on your device.
Website malware: Just as your computer can be infected with malware, so can your website. Website malware can be particularly devious - its effects can include:
Changing the appearance of your website - either through simple defacement, or by placing spam content containing links with the aim of improving the search engine rankings of other sites. Often, if spam content is present on a site, the malware will act in such a way that the rogue content can't be seen by the site admin, but can be seen by visitors.
Redirecting visitors to malicious websites - quite simply, sending visitors to your site to another site which could attempt to scam money out of them, or download malicious software to their device.
Data theft through impersonation - either through installing a malicious form on your site which sends any data inputted to the hackers, or by redirecting visitors to a fraudulent replica of your site.
Spam advertising - by forcing popups and other ads on to visitors, usually encouraging them to visit malicious sites.
Force malicious downloads on visitors - by changing code on your website.
How does malware work?
The non-technical explanation of how malware works is that it exploits weakness in computer and website security to carry out malicious actions.
These weaknesses in website security include:
Using weak passwords that hackers can easily guess.
Failing to update software - either on your computer or on your website (for example, WordPress plugins). Updates frequently patch known security issues, so hackers target people using older software as they aren't protected.
Failing to use anti-virus software on your devices - if hackers can install a keylogger on a device you use to access the admin section of your website, then they'll be able to obtain your password.
Zero-day exploits - this is when hackers exploit a security issue as soon as it is discovered. This kind of attack can be particularly hard to guard against.
Detecting and removing malware from your website is almost impossible to do manually.
As we've already explained, malware on your website may not be obvious and that complicates both its discovery and removal.

There are a few basic steps everyone should take to protect their website and connected devices.
- Use a strong, unique password for every account you have. Learn more about strong passwords in this guide.

- You should update all software as soon as possible, including your anti-virus package.
