I know that a few people have asked about this... It does get flagged as an IRCbot, but Avast lists it as 'PUP' - short for Potentially Unwanted Program, and K7 lists it as 'Riskware'. A think there are a few other coins that do this as well, but from my own experience, I've been running the wallet on a Windows machine for a few weeks now with absolutely no issues.
