Still to be released but initial testing looks good.
"BLADE successfully blocked all drive-by malware installation attempts from the more than 1,900 malicious websites tested. The software produced no false positives and required minimal resources from the computer. Major antivirus software programs caught less than 30 percent of the more than 7,000 drive-by download attempts from the same websites."
