Hello.
There is a link to download HijackThis on one of your mirrors at:
http://s89223352.onlinehome.us/mirror/hjt
that links to:
http://www.merijn.org/files/hijackthis.zip?
and it gives a page not found error. I checked the equivalent tomcoyote.org page and it's working fine, I might add.

Hope this helps,
The Lightning Stalker
