MalwarebytesOver the course of my career, I've seen a lot of hacked websites

Many websites are hacked directly, but we've also seen them hacked because of compromised computers. For example, a keyboard logger might be used to steal login information.

If you build websites, it's important to make sure your computer is safe.

This tutorial will show you how to scan your PC using Malwarebytes.

For Mac users, give our ClamXav tutorial a try instead.

Step #1. Download Malwarebytes

Step #6. Cleanup

Once scanning has completed, you'll either get a message saying no threats were detected or a list of infected files.

Infected files can be quarantined all together or individually. Before quarantining or deleting, you should make sure that the files are not false-positives. If you're not sure and if the file doesn't contain sensitive information (e.g. an email), you can upload the file to https://www.virustotal.com to get a second opinion.
