A two-headed calf might cause a sensation at the State Fair, but two-headed antivirus tools are more and more common. The concept makes sense. By integrating two antivirus engines into a single product you get better detection without the potential conflicts from using two separate antivirus tools. TrustPort Antivirus 2011 ($34.10 direct) integrates two well-known antivirus engines, but doesn't demonstrate any real benefit from the pairing. Double Anti-Spy Professional v2 ($29 direct, 4 stars) another twin-engine antivirus, labels its two engines "A" and "B" (though it's no secret that A comes from Sunbelt and B is a combination of Agnitum and VirusBuster). TrustPort clearly identifies its engines by name. One is the engine behind AVG Anti-Virus Free 2011 (Free, 3.5 stars), and the other powers BitDefender Antivirus Pro 2011 ($39.95 direct for three licenses, 3.5 stars).
