the wallet is fully functional and safe to use in windows. it may raise flags but poses no risk on your system or your money.
 
Note that; each antivirus vender targets a specific aspect and per-to-per linkage signatures(eg BitCoinMiner) are a common flag various antivirus detect.
If it suits you, currently am working on version 1.0.0.2 of our wallet. it will solve most of this issues but i wunt guarantee it will not raise the same flags because, pulling out some of this core codes exposes the wallet to previous risks faced faced by bitcoin back in 2011 like keylogger viruses.
