Win32:Trojan-gen. {VC}

I downloaded a couple of Demos from http://www.pixelgenius.com/
PhotoKit & PhotoKit Sharpener

avast! claims to have found a virus - Win32:Trojan-gen. {VC} in both.
Assuming this is a false positive, how do I allow avast! to run these files without disabling my protection?

If you are getting a virus warning that you believe is a false positive, then if you can zip and password protect (‘virus’, will do) the suspect file and send it to virus @ avast.com (no spaces).

Give a brief outline of the problem, the fact that you believe it to be a false positive and include the password in the body of the email. Some info on the avast version and VPS number (see about avast {right click avast icon}) will also help.

You could also check the offending/suspect file at: Jotti - Multi engine on-line virus scanner if any other scanners here detect them it is less likely to be a false positive.

It certainly seems like a false positive. No need to submit, I have download the package.
