BTW - Virus Bulletin published some older issues of its magazine on their website recently. Namely, the latest tests from 2003 could be found here:

Virus Bulletin 02/2003 - Windows NT SP6, page 16
Virus Bulletin 05/2003 - RedHat Linux 8, page 18
Virus Bulletin 06/2003- Windows XP, page 15

And there is also the standalone avast! (and BART!) review in the
Virus Bulletin 07/2003 - you can find there what experts think about your antivirus program ;D ;D !
