AV performance test from AV-Comparatives

Like the title says, AV-Comparatives have done a performance test on most major AV programs (note; paid editions).
They have tested with both standard AV-settings and high ones.
They've tested copying files, archiving/unarchiving Office 2003 files, encoding and transcoding of music and video files and the system booting and shutdown impact on a Core2Duo 8400 with 2GB memory and XPSP3.
Antivirus detection rates have not been done in this test, it's only a performance test.
The top 5 are;
1 Eset NOD32 3.0
2 Symantec NortonAV 2009
3 VBA 32 3.12.8.2
4 Avast Professional Edition 4.8
5 McAfee VirusScan Plus 12.1

Check the testing methodology and results yourself here/PDF link.
Avira and Avast have gotten an Advanced + certification and AVG an Advanced one (for what it's worth ).
Cheers.
