Is Bitdefender "Free edition" deserves the trust ?

Hi there ! I'm newbie here.
I have installed Free Bitdefender and I have a little question...Today I got suspicious file via email (copy.exe). I run on-demand scan with BD and saw the message that the file is clean. After I uploaded this file to Virustotal and saw that there is a malicious. Bitdefender has detected this trojan .
~Virus Total link removed per Policy~
I wonder, why Bitdefender Free does not detect a threat ?

Is very possible that VirusTotal executes the files first, allowing BitDefender Active Virus Control to react
Trie to execute that sample inside a Virtual Machine

 

That might be a bit too advanced considering that the OP is a "newbie".

Instead I would say that you can safely delete that file as it clearly is malware! Whatever you do don't execute it unless you know what you're doing

 

Thanks for the reply!
But the signature is the first line of defence. And as far as I know, Virustotal does not use heuristics or sandboxing. And if You notice, that GData, Escan, and F-Secure were detected this malware by the signature from Bitdefender.

 

I am quite an experienced user. But thanks.
I'm just trying to understand why the free product is defective.
At first I would like to get an explanation on the official Bitdefender forum, but BD-forum is off.

 

Well, considering the OP is a "newbie" and the nasty Rootkit they have in their hands is not; then I would recommend to delete all such instances

Active Virus Control is not sandbox or signatures; is process monitoring feature of BitDefender and possibly the most useful when catching malware

 

Ok that's good.

I read that like you were a newbie, but I guess you meant you were new here.

Anyhow then I guess you know what to do and what not to do

 

There was the same issue here:

The OP indicated that the problem was solved after the latest update. So it might be just a bug.
