Not sure what avast product you are using, I don't know if the avast! Server Version (the forums you posted in) is different to the standalone/client avast applications, but and Malicious URL alerts are normally done by the Network Shield.
I haven't heard of the Mom Logic, that you mention unless this is a site called momlogic ?
However, I visited the link you gave and no alerts from avast. Mind you I have Firefox with NoScript and RequestPolicy and I notice your site has a massive amount of cross site scripting, one to momdot.com and momselect.com along with a few others with momms in the domain name.
Even temporarily allowing cross site scripting avast doesn't alert, so I'm at a loss as to the problem. A screenshot of the alert window would be helpful.
