This virus/worm (which introduces a password stealing trojan as its payload) is not that new. For example, McAfee discovered the version 'a' varient on April 11th.
It is also interesting to note that the heuristic scanning part of Mcafees AV scanner flags this as a potentional virus, even when running an out of date DAT file. Which I guess proves heuristic scanning can work.
It shouldn't affect any work related systems (if your firewall/AV software isn't blocking this sort of thing, then you should get a new admin guy ). Instead, it has tended to infect home systems which do not have up to date AV software active.
