Trojans & Security

Published on: April 15, 2025

We recently posted about new security features in version 5.0.0.4 of daytradr. These changes were made in response to security threats mainly from China but also the Middle East.

Some of these changes have started to flag as a threat on BitDefender and yesterday in Windows Defender. These are false positives. In other words – antivirus thinks there’s a Trojan in there, when there isn’t.

The cause of this is our use of tools to hide sensitive parts of code – such as communications with servers and encryption. This protects you and your data and protects the product from piracy. The techniques used since 5.0.0.4 are very similar to techniques that are used to hide virus code. When the antivirus sees this – it mistakenly thinks the files is infected.

One customer reasonably asked “How is it almost every other software on the planet doesn’t have to jump through these hoops and yet their code isn’t hacked?”. That’s a great question. In the trading industry, almost all platforms have been cracked and are available in China for pennies…

Not only the platforms – data feeds have been cracked too. You can get market data for pennies permanently from unregulated Chinese sites. Data vendors have free trials – but the Chinese have figured a way to make demo feeds available forever – bypassing checks that prevent abuse of demos.

As to why 5.0.0.6 flags as a Trojan and other software doesn’t – it’s not 100% clear but it’s down to the signature databases that the antivirus companies use. There’s a process to get out of the database by reporting the false positive – which is being done as we speak. We are also going through a process of getting whitelisted by them to prevent it occurring again. 

I understand the frustrations of having to deal with this – it is unfortunate but it is something we can resolve without exposing your data.
