In a step that should help make the Internet safer for consumers, anti-virus giant Symantec on Wednesday will introduce a protection system designed to anticipate new ill-meaning programs that try to steal onto your computer.
For decades, anti-virus protection has worked by reacting to new ill-meaning programs. Researchers rush to identify bad code, then create and distribute filters for it. But cybercriminals have got so fast at escaping the latest filters that protection often comes too late.
Symantec’s new system, called Quorum, continuously predicts whether any new program that attempts to run on your PC is good or bad. It then takes steps to isolate the bad code. "We’re closing a major gap the bad guys have been using to deliver their ill-meaning software," says Rowan Trollope, senior vice president of consumer products.
Symantec becomes the fourth major anti-virus firm—and the largest—to add predictive capabilities to traditional reactive anti-virus systems. Since February, McAfee, Panda Security and Trend Micro have introduced similar predictive technologies.
Computer infections most often spread when a PC user clicks on an altered Web link that arrives in an e-mail or social-network message, or appears in search results for questions on Google, Bing and Yahoo Search. What’s more, millions of lawful Web pages—unknowingly altered by hackers—can also infect a PC during a page visit.
Cybercriminals use infected PCs to spread junk e-mails, steal data and hijack online banking accounts. Infections can change hourly, forcing anti-virus firms to create and deliver thousands of filters each day. "The amount of ill-meaning software produced today has required all of us to change the approach we take in combating it," says Trend Micro senior manager Jon Clay. Trend began offering predictive protection to business customers in May. A consumer version is due next year.
"There is a natural evolution taking place," says Mike Gallagher, chief technology officer for McAfee, which rolled out its Artemis system for consumers and businesses in February.
Symantec introduces Quorum in its new Norton Internet Security 2010 system for consumers priced at $70 for a one-year subscription; McAfee’s consumer subscription is priced similarly. Panda Security’s free consumer version of its Panda Cloud anti-virus product has been out since April.
In the past decades, anti-virus protection hasn’t worked effectively because _____.
选项
A、researchers didn’t create filters in time
B、filters were soon escaped by cybercriminals
C、ill-meaning programs were too complex
D、cybercriminals were smarter than researchers
