It is only as good as the malware samples employed. Appears DNS-changer and scareware samples were not employed against Avira. Even if they were, the variants that you were hit with obviously were not. Also of note by this statement: You are running a non-default setting configuration. Bottom line - AV Lab tests are "best guess" rough approximations on how AV software will perform under default settings for the average user. Note the like worded AV-C disclaimer I posted in reply #5. Also of note is "the default setting" rule is no longer an absolute in AV lab testing as noted in AV-C's recent test of Enterprise products. So these reports need to closely examined for like particulars; not just a review of any graphical results chart.
