Spyware.agent detected by Malwarebytes - is it serious?

[Mizgal]

Greetings, 
my Malwarebytes detected a file on a hard drive of my second PC: "Spyware.Agent"; it was quarantined. 
I have not observed any abnormalities in regard to how this PC works. I have no idea where could I catch this infection, since this machine is rarely used.  Is it possible for it to be false positive? If it is real threat what kind of damage may be inflicted by the virus? Data theft? 
I kindly ask for your help.

Can you please zip and attach a copy of the file being detected here?

 

Thanks

Thank you for your reply,
in order to do that do I have to restore the file from the quarantine?

Yes

OK, I've done this. 
BTW, after logging in Command Prompt was on for a few seconds. 

The attached file was classified as:

BITAD62.zip

Additionaly, on another scan MB found the in different locations:
In contrary the on one the desktop, which was not a surprise, the second in the Windwows\Recent folder is a bit worring. But if I am correct, it was found there due to me using the file to zip it and it is just a shortcut created by Win?
