So it needs an update in the program version to be able to 'clean' up the virus/worm. but only an update in the VPS to pick them up.
Is that correct?
Yes, that's quite correct. The Virus Cleaner is not in the virus database under BART (that's because we don't generally have a temp dir so the cleaner module is just on the CD).
If so, will there start being updates to the program version more regularly? IE when Avast!4 is updated?
Absolutely. Not exactly when avast4 is updated, but whenever the Virus Cleaner is updated (not always the same, but usually even more often than avast 4 itself - anytime a new "blockbuster" virus shows up)...
Anyway, the reason we've waited so long with the latest update was that we were worried about the updater (the BART CD Manager). The updating code was completely rewritten and we didn't want to release a BART update before we were sure it'd work (so we've been actually 'testing' it on regular avast 4 users, as the updating code is shared). Now the updating code will be frozen, and we can issue updates much more often.
Hope this helps,
