The problem is in the IRC module used... it cuases false positive.
I use this and other wallets that have this type of false positive problem in some antivirus and I have not had any problems.
Again, the solution is not to set up exclusions. That's like asking for only pain medication when you have a broken leg. This needs to be fixed by the dev.
I agree that the solution isn't to set up exclusions, the better and right solution is to update the wallet so that ideally, the wallet isn't detected as a virus. At the moment, a non-techie person would likely be scared off installing it if their AV program alerted them to a virus and that reduces the likelihood of wider, mainstream coin adoption.
