One-Click Linux Malware & Rootkit Scanner Using ClamAV and RKHunter

Secure Your Linux VPS in One Click with Our Rootkit & Malware Scanner

Running a VPS or dedicated server? One of the most overlooked but critical steps is making sure your system is free of rootkits and malware.

To simplify this task, we at Hosteons have released a free and open-source script that automatically installs, updates, and runs malware and rootkit scans using two of the most trusted tools in the Linux ecosystem:

  • ClamAV – an open-source antivirus engine
  • RKHunter – a rootkit scanner that checks for backdoors, local exploits, and suspicious files

🔧 What the Script Does

  • Detects your Linux distribution (Ubuntu, Debian, CentOS, AlmaLinux)
  • Installs ClamAV and RKHunter
  • Automatically updates malware and rootkit signature databases
  • Fixes common errors like WEB_CMD=”/bin/false” in RKHunter config
  • Runs full ClamAV scan
  • Executes a complete RKHunter rootkit check
  • Compatible with minimal or fresh VPS installations

📥 Download and Run

Run the following commands to download and execute:

curl -O https://raw.githubusercontent.com/hosteons/linux-malware-scanner/main/scan.sh
chmod +x scan.sh
sudo ./scan.sh

Or get the full packaged ZIP with README and LICENSE:

👉 Download from GitHub


📋 Output and Logs

  • ClamAV scan will output infected files (if any)
  • RKHunter will show warnings and potential issues
  • All actions run with user confirmation and are fully transparent

⚠️ Note

This script is non-destructive – it only scans and reports. It does not automatically delete or quarantine any files. Always review flagged files before taking any action.


🎯 Why Use This?

  • Ideal for hosting providers and system admins
  • Perfect for VPS users looking for a quick, effective scan
  • Good first step after initial OS setup

💡 Self-Hosting vs SaaS: Why Developers Are Moving Back to VPS

In recent years, Software as a Service (SaaS) has dominated how we consume tools — from CRMs to project managers and even basic email. But in a surprising twist, developers are increasingly ditching SaaS in favor of good old-fashioned self-hosted applications on VPS (Virtual Private Servers).

At HostEONS, we’re seeing a growing wave of developers deploying self-hosted solutions like Nextcloud, Ghost, Outline, Forgejo, Matomo, and more. Here’s why.


🏗️ The SaaS Problem: Convenience with a Cost

SaaS makes it easy to get started — no server configs, no deployment — just log in and go. But that simplicity comes with hidden tradeoffs:

  • 💰 High monthly fees
  • 🔒 Limited control over data
  • 📦 Feature gating and vendor lock-in
  • 📉 Performance throttling on lower-tier plans
  • 🔕 No control over updates or platform decisions

SaaS is convenient, but you’re renting access, not owning your workflow.


🔁 The Shift: Developers Reclaim Control with Self-Hosting

Today’s developers are tech-savvy and privacy-conscious. Many are turning to VPS-powered self-hosting to take back control — and not just for cost savings.

Here’s why self-hosting is making a comeback:


✅ 1. Full Data Ownership

Self-hosting means your data stays on your terms — not in some multi-tenant cloud environment. Great for:

  • GDPR-conscious projects
  • Security-focused devs
  • Auditable and transparent operations

✅ 2. One-Time Costs, Not Monthly Drain

Most SaaS tools start cheap but scale poorly. Self-hosting on a VPS is:

  • Cost-effective
  • Predictable
  • Scalable without high license jumps

You pay for what you use — not for every user or feature toggle.


✅ 3. Customizability

Open-source, self-hosted tools are often highly customizable. Developers can:

  • Change UI
  • Extend functionality
  • Connect to internal systems without API limits

Try doing that on a closed SaaS dashboard.


✅ 4. Learning and Empowerment

Self-hosting helps devs:

  • Improve their sysadmin skills
  • Master Docker, NGINX, systemd, backups
  • Build portable infrastructure knowledge

Perfect for freelancers, devops engineers, and indie hackers.


✅ 5. Tool Independence

SaaS services can get acquired, shut down, or pivot. With self-hosting:

  • You’re in control of updates and versioning
  • You’re not forced into UI overhauls or “enterprise upgrades”
  • You can run the exact version you want — forever

🧰 What Developers Are Hosting on VPS

Some popular self-hosted apps we’ve seen deployed on HostEONS VPS plans include:

  • 🚀 Nextcloud (cloud storage & collaboration)
  • 📝 Ghost (blog/CMS)
  • 🧠 Outline or Logseq (internal wikis)
  • 📈 Matomo (privacy-first analytics)
  • 📦 Forgejo / Gitea (self-hosted Git platforms)
  • 💬 Rocket.Chat / Mattermost (chat servers)
  • 📂 FileRun or Seafile (file sharing)
  • 🌍 OpenVPN / WireGuard (self-hosted VPNs)

🧭 Conclusion

SaaS still has its place, but developers are increasingly realizing the power, control, and freedom that comes with self-hosting on a VPS. It’s not just a technical decision — it’s a philosophy of ownership over access.

At HostEONS, we’re proud to power that movement.
