a boot infector affecting your dsl speed is unlikely... more likely
it's a more conventional worm/virus that simply isn't detected yet by
the products you've tried so far...
without a suspect file to send in for analysis i would first take a
look at the fact that your dsl is slow - it may be slow because
something is using up your bandwidth... tcpview from
http://www.sysinternals.com can show you which processes are using
ports and therefore which one(s) may be affecting your dsl speed...
there may well be plenty of legitimate entries though (like your web
browser or msn messenger or your email client, etc)... if there are any
that you can't rule out as a cause of the problem you should send it to
an av developer for analysis...
