Missed Trojan

[rfin16]

Windows defender has found a Trojan Jupitr A exploit on my hard drive twice and quarantined and deleted. I only use Defender for occasional scans but have MBAM working for full-time protection. Why won't it pick this up and block it before it gets on the system? Thanks for your feedback

Might send this to VirusTotal. Could be a false positive.

You have basically provided a nickname to a detection but we need know exactly what Microsoft's software actually defined this trojan to be to be able to respond.  That is we need the actual name not a paraphrase of its detection name.

Example:  TrojanDownloader: Win32/Jupiter

You can see how the name is formatted i the above.   Just from the name we can deduce information on this item. 

Please do one or both of the following.

• Submit the sample to Virus Total and provide the Report URL in your reply.
• Submit a sample to Malwarebytes for examination ¹in;  Newest Malware Threats

I will follow this advice next time it shows up as Defender deleted so cannot trace the information now. I was just wondering why MBAM would not report that or block when it's set for real time protection and Defender only runs occasionally. 

Thanks for your advice. 

Best regards

That would come from knowing what "it" is.

Thanks again. Hopefully I will not see this again, but if I do I will remember the suggestions and report more fully.
