Well, I just thought that if there’s a bug in checking the requirements, it might be nice to fix that (though I’d have to know the exact line shown in the log at least).

As for the resource usage, I’m quite familiar with the scanning engine and virus database layout, so yes, it’s definitely lighter, and I’d be happy to tell it to your systems… but I guess there’s no point in trying anyway.
(Sure, if you’re running Win9x, you’re out of luck… but I’m afraid we can’t be stuck with ancient development tools forever, as it would limit the possibility of new features for newer OSes - and anything produced by any newer MS compilers simply doesn’t load on Win9x due to some stupid dependencies in their runtime).

But yes, I probably can’t help you with avast! 4.8, sorry.
