Every time a virus is exposed that tries to download from some fixed location, I've wondered why virus writers would even try such a thing, when it's obvious that white hats will reverse-engineer their code?

    What if the next version uses something more flexible... like a Google search on some particular string? Spend a few months sprinkling links to the download on servers around the world, with pages containing some unique string (call it "foo123"). When the next virus activates, it does a Google search for "foo123", and downloads its replacement. As fast as hosts are removed, more can be created and indexed.

    For even better effect, use a moderately common word or phrase that Google couldn't remove from its index without causing big problems.

    On the non-technical side... I was struck by the post in a previous SoBig discussion that noted that this variant expires on 9/10, and if the F-Secure expert is right, that's not a good sign:
