Same Artemis number both times?
What you do depends on what the file was that McAfee didn't like. "Artemis" is for something highly-suspect which could though still be quite innocent. The file's been put in quarantine but you can see it by opening Security Center and going to Navigation --> Quarantined and Trusted Items.
Info on what to do is in https://community.mcafee.com/docs/DOC-1265
Thanks, yes the same one both times ... pls bear with me, I open up McAfee but can't see the "Security Centre" ... what am I missing??
