This month's MSRT (cited above) adds detection/removal of:

Win32/Babonock - a family of malware that spreads via removable drives, steals sensitive information and downloads and executes arbitrary files.

Win32/Redyms -  a family of trojans that redirect search engine results that may pose as a fake Adobe Flash installer. In the wild, we have observed it being distributed by the Blackhole exploit kit.

Win32/Vesenlosow - a family of worms that collects information about your computer to send to a remote server, and spreads via removable drives.
