AV suites did not fare well, except for Kaspersky and maybe one other, in the Matousec tests. Evidently this is due to the test being designed to test HIPS. I have no idea why one suite uses HIPS in the firewall and most do not.
However, I continue to trust suites, and AV Comparatives whole product (Dynamic?) test is the most real world test. I have used Avast Pro along with Online Armor free firewall, I think that probably gives about as much security as reasonably possible.
Avast is an excellent AV, and I recommend you check the AV Comparatives tests.
