hey guys im juz wondering whether how does avast’s alert is when it detects a piece of malware dat is totally unknown… which is not in d signature database? O.o
If the virus is “totally” unknown it can’t be detected.
At least the behavior or the heuristics should know something about the file 
lol true also… i barely see d heuristics come into action i only saw it once lol
