The document discusses different types of antivirus testing methods and potential ways to exploit weaknesses in those methods. It describes "wildcore" testing using real malware samples and "zoo" testing using large malware collections. It also outlines "retrospective" testing using older signature databases. The document suggests hacks like automatically signing samples, customizing settings, and detecting other antivirus products' false positives to manipulate test results. Feedback from the antivirus industry is mixed, with some condoning common practices while others find them problematic.
