Advice Request Concerns about Crystal Security

[bugjailer]

How is Crystal Security free? Is there a business model here?

Does this software run alongside traditional AV software without conflicts? I am currently running Comodo Firewall (free) and Kaspersky Free AV.

The software scans files in the cloud. How does it achieve this? Does it hash them and send the hash to for example, VirusTotal?

Edit: The answer to Q2 seems to be yes. Can I run Crystal Security alongside Eset Smart Security

Hello @bugjailer

Thank you for your interest. I am sorry about no reply via e-mail.

Crystal Security is absolutely free to for home and business users. There is no business model.

Does this software run alongside traditional AV software without conflicts? I am currently running Comodo Firewall (free) and Kaspersky Free AV.

Yes. You can use Crystal Security alsongside traditional Antivirus software.

The software scans files in the cloud. How does it achieve this? Does it hash them and send the hash to for example, VirusTotal?

Collective engine uses VirusTotal API service to analyze detected files - only the hash codes are compared.
When unknown executable is detected then it will be fully uploaded to the VirusTotal service.

There are also in-house engines to provide additional detection. You can use Crystal Security even without internet connection.

If you have any other question or feedback then please let me know anytime via email or here.
I will try to respond faster to emails. I apologize for the inconvenience.

Crystal Security can start with windows or you can just use it on-demand.

There is also a portable version available.

The settings are pretty cool as well. Something to experiment with wnen you become more experianced with it.

I was getting several BSODs in a row.
I booted into safe mode and left Windows running for a couple hours. No BSOD.
Restarted Windows and slowly restarted each security program. No BSOD.

Not sure if Crystal Security was the cause of this.

On an issue that was definitely caused by Crystal Security, it was blacklisting and deleting my Steam files whilst I was gaming. I had to disable active protection. Is this a known issue?

Hi @bugjailer

Thank you for the feedback. Sorry about late reply.

I was getting several BSODs in a row.
I booted into safe mode and left Windows running for a couple hours. No BSOD.
Restarted Windows and slowly restarted each security program. No BSOD.

BSODs should not be related to Crystal Security.

On an issue that was definitely caused by Crystal Security, it was blacklisting and deleting my Steam files whilst I was gaming. I had to disable active protection. Is this a known issue?

This is not a known issue. Recently there have been very few False Positive reports.

Can you please tell me which Steam files were removed? Should be listed under Blacklist section.

You can restore removed files via Blacklist section.

Your feedback is much appreciated.
