What is PDF2Docs?

How do I remove PDF2Docs?
Our program Malwarebytes can detect and remove this potentially unwanted program.
[Mindspark only]You can use their own uninstall instructions first, but I would advise to follow the steps below anyway.
- Please download Malwarebytes for Windows to your desktop.
- Double-click MBSetup.exe and follow the prompts to install the program.
- When your Malwarebytes for Windows installation completes, the program opens to the Welcome to Malwarebytes screen.
- Click on the Get started button.
- Click Scan to start a Threat Scan.
- When the scan is finished click Quarantine to remove the found threats.
- Reboot the system if prompted to complete the removal process.
- No, Malwarebytes' Anti-Malware removes PDF2Docs completely.
- If your browsers have been hijacked, you should read our Restore Browser page. You can read there how to fix additional browser redirect methods.
We hope our application and this guide have helped you eradicate this hijacker.
As you can see below the full version of Malwarebytes would have protected you against the PDF2Docs hijacker. It would have warned you before the application could install itself, giving you a chance to stop it before it became too late.
