There are many automated malware analysis services available on the internet, some of which are free. New malware samples could prove too complex for analysis using cloud automated malware services. An analysis of the malware on the tool could yield a detailed report (mostly in HTML, PDF, XML etc); this report might have lots of details including details about the DLLs used by the malware sample, summary of files and directories accessed by the binary sample. At the same time, lets remember that there are instances when the results yielded by such an analysis would turn out to be false positives.”]
