Performance
BullGuard put in a rather mixed performance in recent tests by SE Labs and AV-TEST – it hasn’t appeared in AV Comparatives’ tests since 2018, so there’s a bit less data to inform our conclusions than we have for some rivals. Its biggest problem is that, by the latest test data, it’s not been as effective at protecting against malware as Windows Defender.
It came last in SE Labs’ protection tests, with a protection score of just 87 out of 100. And in AV-TEST’s latest trial, unusually scored 98.9% when detection malicious samples from a reference set of viruses, as well as failing to get a perfect score in the following month’s real-world zero-day malware exposure test, with a rating of 99.50%.
Its system load is roughly equivalent to that of Windows Defender, and it misidentified seven legitimate programs as malicious in AV-TEST’s trials; it didn’t pick up any false positives when SE Labs tested it.
