wow! i just checked my buzzcoinqt file that I downloaded months ago, and it gave the same result! Devs you have to explain this if you expect people to trust you.
Yes, these are false positives. if you look through the entries, AVG and Avast list it as 'PUP' - Potentially Unwanted Program. The IRC references are just from connecting to the network. Kapersky and ZoneAlert list it as 'not-a-virus' and K7 list it as 'Riskware' as opposed to anything specific. There are other coins that will generate similar results.
People have been running this wallet with no security issues for months, but regardless. it will hopefully be addressed in the new wallet!
