I score antiphishing products by comparing them with Norton AntiVirus (2014)$49.99 at Norton, which consistently does well. Norton managed 98 percent detection this time, so with a detection rate of zero, Baidu's score is minus 98 percent, a new low.
"But wait," you say. "It's not fair to compare the free Baidu against the commercial Norton!" Perhaps so. Let's look instead at Bitdefender Antivirus Free Edition (2014), which actually scored one percentage point better than Norton. FortiClent came in just four percentage points behind. Sorry, Baidu, free is nice but it's not an excuse here.
