JayShield® Free malware scanner for websites

Find the malware hiding in your website.

When hackers get into a website, they leave hidden files behind. JayShield finds them in seconds and locks them away. It never deletes a file unless you say so.

Detection

What it catches.

Five kinds of threat, tested on real websites so it flags attacks and not your own files.

Back doors

Secret entry points hackers leave behind so they can get back in later. JayShield finds and removes them.

Hidden code

Code scrambled so people cannot read it. JayShield spots it anyway.

MEDIUMthemes/site/footer.phpobfuscation.base64_chaincode analysis

Code hidden in images

Fake photos that secretly run code. A favorite trick in upload folders.

FAQ

Questions.

Is the scanner really free?

Yes. The full scanner is free forever, with an open MIT license. Nothing is held back to push you to Pro. If the free version is all you need, that is all you need.

What does Pro add?

Pro does the work for you. It scans all your sites on a schedule and in real time, updates itself, alerts you by email or Slack, and gives you a dashboard, one-click fixes, PDF reports, an API and a commercial license. It is made for people who look after more than one site.

Does JayShield send data anywhere?

The free scanner sends nothing, ever. It runs only on your computer. Pro sends only the scan results you choose to show in your dashboard, and never your files.

What if Pro is not right for me?

Pro comes with a 14-day refund. If it is not right for you, email info@JayHackPro.com and it will be sorted out.
