OK, I'll try to explain. When the Cleaner is updated, it's compiled and put to web for download (as standalone exe). During the
following VPS update, the special Cleaner, included inside the VPS, is updated as well. So, it certainly can happen that the downloadable exe is slightly newer than the one in the VPS file (if the VPS isn't updated for some time).
Of course, if anything really bad happens, we can release another VPS update just to update the included Cleaner; usually, however, the Cleaner update is not that important - the most important is the detection that prevents the malware from infecting your computer in the first time.
Having said that, I should add that I found a little problem today; due to an error in the building process, the last two versions of the Cleaner didn't make it to the VPS update - so it wasn't updated longer than expected. However, it was the first time anything like that happened, and it won't happen again
Don't worry, the changes were only marginal, so you aren't missing anything anyway.
