Well, it’s not sensible to send every single file to the cloud for being scanned that would make the whole process slow and time-consuming. The advantage of relying on cloud technology is that the antivirus software would be very light on the computer all the heavy scanning work is carried out on the server side. Alongside, there are some that use only the cloud protection method. While there are still many companies that use the traditional method for their antivirus software, there are some that blend the traditional method with the cloud technology. It’s here that the cloud technology comes in. They have to keep their antivirus programs fast as well as light so that they don’t slow down the computer in which they are installed. So, what exactly is happening? A single file is being cross-checked against a database of files, millions of files.Īs newer virus definition files get added to the database every day, things turn out to be really challenging for any security firm that manufactures antivirus programs. (It’s therefore that we have to keep updating our antivirus software, to keep adding newer and newer virus definitions every day). Every day, as new and new malware are being created, the database goes on increasing in size. The antivirus programs try to find out if there is a match. Traditional antivirus programs detect malicious codes by cross-checking with the database of virus definition that they have.
