Quite complicated to get a clear overall picture because the results are spread out over 12 separate reports, yet Avira seems to be the clear winner with an average performance degradation of 0.130 seconds, whereas the competition lies somewhere between 0.300 and 0.500. It's also noteworthy that the all-time performance test winners Kaspersky and Bitdefender are the worst performers in this roundup, with 0.578 for Kaspersky and 0.766 for Bitdefender. GDATA's 0.759 are expected.
