I've just posted a pre-release of ClamWin Portable0.88.4. This new release features the following changes:
Live CD Support - ClamWin Portable now supports running directly from a CD. This will only work in its default directory layout with no INI. Be sure to run it locally first and download the latest virus definitions before burning to CD.
In-Place Upgrades - ClamWin Portable now supports the ability to do what I'm calling an "in-place upgrade". This means that you can extract it right over an existing installation of ClamWin Portable without losing any of your existing data and it'll Just Work (tm). Obviously, this will be going forward as you'll need to manually upgrade this time due to the new directory layout.
30% Smaller Install - ClamWin Portable is now 30% smaller (7.7MB compared to 10.8MB) thanks to PPS noticing that PYDs can be compressed (turns out they are DLLs).
