ESET undetected a HackTool.Keygen.exe, why?

[moeetee 0]

I downloaded the above mentioned file with a program to get it cracked. MalwareBytes picked this up when I opened this file, and deleted it. Why didnt ESET pick it up?

 

I disabled the Malwarebytes to get the keys from the keygen and then re-enabled MWB and it detected it and deleted it.

 

Including my first question and doing a full scan with ESET and find nothing, what can I do to ensure there was no backdoor of this keygen that is undetectable?

We do not detect keygens or cracks unless they are malicious or there's a good reason to detect them.

Seriously?

I believe some products may flag keygens up because they are illegal rather than dangerous although I'm not 100 percent sure on that one. However the problem with using keygens and cracks apart from the legality side is you never know what you are getting - there is always a risk.

Deff understood. Other than scanning via ESET. What can I do to ensure that there is nothing other than the intent of the .exe? Do you suggest any other deep scanning to make sure there was no backdooring?

If ESET doesn't find anything with detection of pot. unwanted and unsafe applications enabled, then the machine should be malware-free.

If you want to detect all benign illegal tools then it's a different story. As I wrote, ESET detects primarily only malicious executables or tools that can be misused in the wrong hands.

As marcos has said it probably is safe. But I always say as they have not came from official sources there is always a risk.

The reason MBAM detected this is because this is what the app was designed to do years ago when it was created. What many don't realize about MBAM is it scans for software illegally obtained or that can be used for like nefarious purpose.

It's normal , a normal keygenerator doesn't do any harm to your computer , whether to use is a personal choice , and that doesn't say it's legal.

So no detection is normal , a detection I can consider it to be a false positive.
