What does your website look like a malware site?
I'd be more inclined to download and try your software otherwise. Maybe its the ads?
I'd also be inclined to actually purchase the software if it met my needs.
I don't need full on photoshop (price aside), so I'm hunting for something that would allow me to edit/create diagrams and supports layers. This seems like a good fit.
Just some things to consider. =)
