Hi, I'm getting recurrent threat warnings from AVG about OSX/InstallCore.O, which are from reputable software package contents (e.g. Skype in the example). I'm having a hard time understanding if this is legitimate, and not finding clarity from searches I've done. Is this because Skype used InstallCore to install? I understood InstsallCore is a non-viral adware/malware, so otherwise I don't know how it got into those package contents. Any help would be lovely!
