Cloud antivirus software does most of its processing elsewhere on the Internet rather than on your computer’s hard drive. Cloud based antivirus products can provide several benefits including better PC performance, centralised management, simpler PC deployments and less reliance on users
Cloud antivirus software consists of client and web service components working together. The client is a small program running on your local computer, which scans the system for malware. Full locally installed antivirus applications use massive amounts of resource, but cloud antivirus clients require only a small amount processing power.
The Web service behind cloud antivirus is software running on one or more servers somewhere on the Internet. The Web service handles most of the data processing so your computer doesn’t have to process and store massive amounts of virus information. At regular intervals, the client will scan your computer for any malware listed in the web service’s database.
