Hello Mike,
I clicked on the URL www.aero3d.net and then selected the Edge 540

When I clicked on either of the first 2 models, my anti-virus software detected the worm virus kaza

I never tried any of the other selections.

The only way I know of to get rid of Kaza is to goto www.google.com and search for kaza. From there you probably can still get downloads to eradicate the worm

Thank you for your prompt attention

Billie
