Trojan warnings on genealogy sites

A huge thanks to Alasdair MacDonald from the University of Strathclyde for a warning about two well known genealogy websites which appear to have been hacked by trojan viruses. The first is Castlegarden.org, the site detailing migration to New York prior to the establishment of Ellis Island - the second is the Clan Donald DNA Project site. I've not listed the actual web addresses as I don't want to tempt fate, but Ali comments that several of his students have been hit by trojans from the sites, which neither AVG or McAfee picked up, although Ali himself uses Avast which did pick them up.

You are hereby duly warned!

(Thanks to Ali)
