One morning a customer messages you: “Why does your website send me to a gambling page?”. On your own computer everything looks fine, but visitors coming from Google or from their phones are being redirected. A few days later Google shows a warning and orders drop sharply. This is the typical story of a hacked website infected with malware, and the damage is usually far greater than the cost of preventing it in the first place.
At TWF, we believe website security is not something you only think about after an incident. A safe website must be cleaned at the root, properly hardened, fast and continuously monitored. That is the spirit of the website security, malware removal and speed optimization service TWF provides to businesses.

Why are business websites so easy to hack?
Most websites are not attacked because the business has “something worth hacking”, but because the website has vulnerabilities. Attackers use automated tools to scan thousands of websites, and a single weak point is enough:
- Core code, plugins and themes that have not been updated and contain publicly known vulnerabilities.
- “Nulled” themes or plugins from unknown sources, which often come with malware pre-installed.
- Weak or reused passwords for the admin panel, hosting and database.
- Outdated PHP and server software that no longer receives security patches.
- Overly permissive file permissions, no firewall and no backups.
The 4 pillars of TWF's website security service
1. Root-cause malware removal and incident response
TWF engineers review the entire source code, database and server to find malicious files, hidden injected code, rogue accounts and backdoors left by attackers. Your website is cleaned while keeping all content, products and orders intact. Most importantly, we trace how the attacker got in and close that path, and we help remove Google warnings and get your domain off blacklists.
2. Long-term security hardening
After the incident, the website needs to be properly “locked”: updating the core and plugins, safely upgrading PHP, setting up a web application firewall (WAF), blocking brute-force attempts, enabling two-factor authentication, tightening file and account permissions and configuring HTTPS. Alongside this, automatic scheduled backups are stored in a separate location so your data can always be restored.
3. Page speed optimization
Visitors will not wait for a slow website, and Google favors fast ones. TWF measures Core Web Vitals, finds the real bottlenecks and optimizes them: caching tuned for each page type, image compression and WebP conversion, minified CSS and JS, database cleanup, server tuning and CDN integration such as Cloudflare when needed. For online stores, the cart, checkout and account pages always keep showing correct data.
4. SEO recovery and continuous monitoring
For hacked websites, TWF removes spam pages from Google's index and fixes 301 redirects, 404 errors and the sitemap so your domain regains trust. After that, the website is monitored around the clock, security is checked regularly and you are alerted as soon as anything unusual happens. Results are tracked through Google Search Console and Google Analytics.

Frequently asked questions
Will malware removal cause data loss?
No. TWF always backs up all code and data before working on the site, so your content, products and orders are kept intact.
How long does it take to fix a hacked website?
It depends on how badly the site is infected and how large it is. After the assessment, TWF gives you a specific timeline and cost before starting.
Can the website get infected again?
The risk drops significantly once the root vulnerability is patched and the system is hardened. For long-term safety, keep up regular updates, backups and monitoring; TWF's maintenance plan takes care of this for you.
Does a website that has not been hacked need security services?
Yes. Prevention is always cheaper than recovery. TWF audits and patches vulnerabilities and sets up backups and a firewall before an incident happens.
Does TWF build new websites that are secure from day one?
Yes. Every website in TWF's SEO-ready web design service comes with HTTPS, a firewall and automatic backups from the very first day.
