The problem isn't anything you did. It's your AV vendor.

UPX is often used, and unfortunately, some of the users have nefarious purposes -- meaning that AV software will tend to group your innocent application in with the (relatively few) bad applications made with UPX.

You have about three options:

1) Package with a different version of UPX. (Not a guaranteed solution.)
2) Submit your UPXed application to your AV software vendor as a false positive.
3) Don't use UPX.

Frankly, unless you have some serious space considerations, you should choose option 3. There is really not much need to package with UPX.

Once you are done, try https://www.virustotal.com/ to see what AV software will incorrectly flag your software as infected, and make sure to submit false positive reports to those AV vendors.

Hope this helps!

... my antivirus is sheed!

That product has no commercial presence that I can tell of and as of right now has a whopping 4 likes on Facebook. My guess is that their claim of combining two rival products are either completely made up or the product of piracy; either way drop them.

If you are using Windows, there is no reason why Microsoft Essentials isn't sufficient.*
