When downloading files from the internet, Avast (any antivirus) might block the downloads marking them as infected by DRep. The message is a bit misleading because DRep is not a virus infection but rather a preventive downloading blockage. DRep (DomainRep, aka Domain reputation) is a preventive detection of antivirus that blocks EXE file (Windows executables) downloads if all these conditions are met: 1. The file is not prevalent enough, ie. not enough users launched the file yet, 2. The domain is not prevalent enough, ie. not enough users downloaded (any) EXE files from the domain yet, 3. The file is not digitally signed or antivirus does not trust the signature. Once one of these conditions are not met anymore, the antivirus will stop flagging the download. This is a preventive error that does not depend on the contents of the file. The antivirus does not examine if the file is infected by a virus or not.
