I just noticed something strange with Prevx.. well this is what happened i downloaded a file once it finished i didn't click the setup file, instead what i did was right click it and pressed 'Scan with Prevx 3.0' it finished scanning the setup file and nothing came up i still defenently had a feeling this executable was defenently infected so i scanned it in Jotti and most came up with Trojan/Dropper so yeah i was right, yet Prevx didn't detect this when i right clicked and then scanned. However, i then right clicked it and this time i tried 'Scan with MalwareBytes AntiMalware' while it was scanning the file a Prevx alert popped up and said Medium Risk Malware and i had options to either remove it/ignore it etc and i chose to remove it this is good but the thing i'm confused about is: Why is it that when i scanned it, it thought it was clean? Edit: I re-downloaded that same file, this time Prevx detects and removes it automatically as soon as it is fully downloaded and saved onto my hard drive Great!. I would just like to say, Prevx is one of the best in the world at detecting unknown threats Well Done Prevx seriously!!!!!!
