G-Data and F-Secure use the Kaspersky engine. G-Data uses also the avast engine, so it makes a LOT of false positives and is a lot resource hungry. Both F-Secure and G-DATA have a very low proactive detection. Trustport uses 4 engines, that makes it very heavy and still have a very low proactive detection.
So, the Best IS Kaspersky, which founds around 98% by signature and 70-80% by heuristics + proactive d. + HIPS
