AVG Internet Security review: Does it keep you safe? AVG Internet Security achieved a perfect 100% protection rating in the latest tests by AV-Comparatives.org and AV-Test.org. Obviously, that’s as good as you could ask for, but it doesn’t make AVG exceptional: several other products achieved the same score, including the free edition of Avast, which isn’t surprising since the two suites use the same core antivirus engine. Come to that, Windows 10’s own built-in protections came tantalisingly close, with an average score of 99.97% across all of the two labs’ tests. AVG also jumped the gun just a few times, registering three false positives during the tests. Avira, BullGuard, Eset, F-Secure, G-Data and Kaspersky all did better, wrongly flagging up fewer or no innocent files. Still, this isn’t a disastrous performance.
