I'm a bit confused here. I did my normal malware testing today. I first uploaded a sample to VT and two of the vendors included in Hitman detected it as malware. I then scanned the sample with Hitman, and it was indeed detected as suspicious. However, once uploaded to the cloud, it was not detected by any of the engines included in Hitman, even though some of them did detect the sample at VT. How could this be? Are not the definitions of the scanners in the cloud constantly being kept up-to-date?
