Avast! For most of the more techy people have their Avast! products customized to suit their needs. For example. I use Avast! Free. I don’t have a use for Avast! Premier or IS because I don’t do online banking, and I have a Firewall. I have my settings set to be extremely strict due to the nature of what I do. For an average user, they might not customize their Avast! and just leave it. In that case, yes, it might detect. I’ve seen file in SandBoxes being detected as malware. It happens and always will. No need to be concerned
