A Little Info..

-= Would anyone mind to explain these weird names…? And their effects/behavior…? If possible, add more to these “vocabulary words”…

 Vitro
 Vundo
 Win32
 Virtumonde

-= Thank you…

Win32 isn’t a virus, it is just that the malware is going to work on a 32bit version of avast.

Vundo/Virtumonde are aliases of the same malware.

I suggest you have a talk to my friend google, just search for the Vitro, Vundo/Virtumonde malware family names there are many variants, Wikipedia results in the search will normally have a good description of the malware family name.
