as you see from the VT scan there are many others that also do not detect…no security program have 100% detection

send the sample to avast

however there is a possibility it is a False Positive

Since the file is this old, i think it is strange that avast does not detect it if it is malware ???

OK i found the file and check it at Avira lab

The file 'FFF-ReflexV2.exe' has been determined to be 'FALSE POSITIVE'. In particular this means that this file is not malicious but a false alarm. Detection is removed from our virus definition file (VDF) with the version: 7.10.9.72.
