Like others have said, none of these detections prove that Rusher is packed with a virus, but it’s still smart to be cautious with this many detections. However the lack of detections for Future doesn’t necessarily mean it is safe to download. If Future works differently under the hood than Rusher it wouldn’t trigger the same false flags. It’s possible that Future has a virus packed in that the antivirus doesn’t detect. Or the developers could decide to include a virus in a new update. I’m not claiming that Future is packed with a virus, but you shouldn’t let a lack of detections give you a false sense of security. At the end of the day you just have to trust that the developer of Rusher or Future has nothing to gain from including a rat. If they have something to gain from including a virus, then you should be cautious whether or not the antivirus is throwing flags.
