问题是你所谓“杀软需要找个目前无法防御的大规模爆发的病毒来证明云的作用”本身就是荒谬的
云的意义就在于，对新病毒进行快速响应，使之不可能大范围传播
建议你好好读下Avira Protection Cloud（红伞云）官方白皮书http://bbs.kafan.cn/thread-1776350-1-1.html
Hackers attacked with viruses and security experts built massive virtual walls to keep them out. In response, hackers simply kept attacking the program until they found a way through the wall. When they did, security experts responded by making the virtual wall thicker and taller. In response, malware authors simply probed these new antivirus defenses again until they found another weak spot. Then security experts were forced to build yet another wall, which of course the hackers would eventually defeat. Day in and day out, hackers and security experts were locked in a struggle to stay one step ahead of each other.
破解者以病毒发起攻击，而安全工作者建起了虚拟的高墙。病毒作者不停发起攻击直到找到墙的某个漏洞为止。安全专家对此的回应是不停加高加厚这堵墙。病毒作者于是又直接探查这新的反病毒措施直到发现下一个漏洞。于是砖家们只能建起另一座墙，而这座墙最终也会被破解。日复一日，专家和病毒作者陷入了一场只为领先一步的纠缠中。
For many years, this model of reactive defense was the cornerstone of successful internet security. However, this approach was not sustainable. Ever-increasing security measures simply weighed a PC down, consuming valuable resources that were better spent on computing tasks. Users needed smarter protection. More recently, a new challenge has emerged outright cyber warfare waged by experienced professionals. Today, hacking is no longer the work of lone individuals writing malware for their own mischievous entertainment. There are organizations that specialize in consumer and private espionage, data theft, identity theft, money laundering and all manners of internet fraud and blackmail-and they are good at what they do.
许多年以来，这种被动防御的模式成为了成功网络安全的基石。但是这不是一种可持续的模型。逐渐增加的安全措施拖慢了计算机，占用了本应用作PC里其它用途的计算资源。用户需要一种更智慧的保护。最近以来，安全专家的虚拟作战出现了新的挑战。今天，破解和做免杀不再是个人的莫名其妙的娱乐行为。一种针对消费者的专门进行隐私揭露，偷取信息，窃取身份等等恶意活动的组织已经出现——而他们确实擅长于此。
The major difference is that this new generation of hackers now has access to the same antivirus programs as the users. Once they posses the actual antivirus product for themselves, writing a new malicious code becomes easier.They simply use an automated process to test their codes until they find a particular permutation that gets through the wall. Therefore, thicker walls are no longer the answer. Simply placing PCs behind massive Firewalls and filling them full of cutting-edge malware detection only defends users against known threats. A new way of thinking about antivirus was needed and it is precisely in this environment that the Avira Protection Cloud was born.
最大的区别在于这种全新的破解与普通用户一样能够得到最新的杀软。只要他们能得到安全软件本身，做免杀就变得很容易了。他们只需要自动化地测试代码，直到发现墙的新漏洞就可以了。因此，更厚的墙就不管用咧。部署防火墙和最新的反病毒防护也只能让用户免受已知威胁的危害。我们需要一种对反病毒的全新思维，而APC就是为此而生。
