Avast's lab test scores range from best to worst. It received AAA-level certification fromDennis Technology Labs and rated Advanced+ in two tests by AV-Comparatives. However, "crazy many" false positives caused it to fail the file detection test from that same lab. Bitdefender and Kaspersky generally take top scores across the board.
In my own hands-on malware blocking test, Avast earned 9.0 of 10 possible point, better than most products tested using this same malware collection. Webroot SecureAnywhere Internet Security Plus (2015)earned a perfect 10 in this test.
My malicious URL blocking test uses newly-discovered malware-hosting URLs, typically no more than four hours old. When I challenged Avast with about 100 of these, it blocked all access to 29 percent at the URL level and eliminated another 43 percent during download, for a total block rate of 72 percent. That's quite good, though McAfee Internet Security 2015 managed to block 85 percent.
Good, Not Great
Avast Internet Security 2015 offers almost all of the expected suite components (parental control is the exception), but their effectiveness varies. I like the innovative home router scan; this is an area that most vendors overlook. And Avast offers plenty of other bonus features. The problem is, top suites just do a better job overall.
