There is no trojan embedded in the downloads, which could mean that it's a false positive. However, Creative Paint is not available for downloading anymore because the official website is discontinued. When you try to access it, a DNS error is displayed, which means that the hosting provider doesn't exist anymore. You will have to use a different application.
For example, Paint.NET could be a good solution for your needs. Give it a try using the following link: http://www.getpaint.net/index.html
