Is there some kind of Cyber Security/Police type agency

refer you to FBI as well.

If it is a hack that doesn't involve demands for ransom, that's a good question. Given there are so many millions likely attacked every day, I doubt there IS any one place to report.

The various software and system vendors are usually the first ones contacted for routine attacks. There are specialized sites and communities that provide help and support for people who have been hacked, including tools to clean up and repair systems. The antivirus vendors also provide resources to identify and respond to many attacks.

For those of us in the industry, there are other highly technical sites for serious attacks. Ultimately, these responses escalate up to CERT.

THere are also corners of the web where the white hat hackers are hard to tell from the black hat ones. Be careful. Sometimes the "fixes" found online are really more malware.

Something happened yesterday that was very disturbing, and I'm not quite sure what to do Thank you for any information you can give me .
