Nothing 'bad' about combofix that I am aware of. Have been advising it's use for over a year :).
Download the HostsXpert.
Run it and press "Restore M$ Hosts File" and press "OK". Exit Program.
Note that if you have a custom host file, this will remove it.
Try the download link now.

I got to the uploading.com site, there was no obvious link to the combo fix program (no "hand" when I moved the mouse over the download area. Now, if I try to go back to that site, it's blocked - it's like this virus is alive and learning as it goes.
click on the "Download For Free" Bar,wait the allotted time, then click download file ,

Do NOT run it from the thumb drive. Move it to your desktop and run it from there.
