I altered your header to include the Artemis numbers which means that the department concerned is much more likely to spot this thread and deal with it without you having to submit anything.
Meanwhile I published a small tutorial on submitting false positives here: https://community.mcafee.com/thread/2016
I'm surprised that Winzip is being stopped by McAfee though. Are you downloading it from source or from a 3rd party?
These falses won't trigger unless you've set Artemis levels to VERY HIGH or HIGH sensitivity.
I've escalated this internally and these should get suppressed soon.
Artemis!FBACDA67D595 & Artemis!95951D40A2F0 are now suppressed. Kindly allow up to two hours for this update to reflect in GTI system.
