Cloud computing brings security benefits

I’ve blogged on cloud computing before and this Technology Review article suggests the concept might be the best way to keep PCs virus-free.

From the second link:

Most people know better than to connect a computer to the Internet without first installing up-to-date antivirus software. But even the best software protection won’t catch every new virus, and performing a thorough system scan can require plenty of processor power, slowing some computers to a crawl.

New research from the Universityof Michigan suggests that computers could be better protected from viruses without sacrificing performance if antivirus software were moved from the PC to “the cloud”–a collection of servers that work seamlessly as one powerful machine. Using this approach, researchers found that they could detect 35 percent more recent viruses than a single antivirus program (88 percent compared with 73 percent). Moreover, using the distributed software, called Cloud AV, they caught 98 percent of all malicious software, compared with 83 percent, on average, for a single antivirus solution.
