Thank you Tech for a most detailed investigative procedure.
After going thru the steps, I'm running most of those progs, I found nothing.
I then contacted a friend on another continent also using Avast and asked him to do a Google search with "downloadsoftware4free.com". Same result, all sites identified with VBS:Malware-gen.
I've decided to add "*downloadsoftware4free" to my filter list inside Webwasher and will therefore no longer come across this site.
Maybe guestlogin just closed off the issue. I really do not need this site as I have enough other sites to obtain to the same info.
