Softonic as well as many other download sites scan all their uploads for viruses. Zipeg has hundreds of virus scan badges of 100% clean over the years. However if you system is already infected by a virus(es) than any program you download may be infected right away.

If is always good idea to scan any of your downloads and if you are suspicious go directly to the source which is in case of Zipeg is:

http://zipeg.googlecode.com
