There are several sites like that, that I believe are just trying to give people viruses and don't have real designs. If they aren't selling something, why would they be giving freebies away?
I stopped going there a long time ago. Not only is it full of viruses, the designs are junk. I liked the artwork on one and pulled it into my digitizer to fix it up and I couldn't save it without an error message. Those designs are not worth the space they take up on the computer. I'm ashamed of all the time I wasted going there when I was a newbie.
I got that also a couple of times so I stopped going there. It is strange because I've gone there for years.
