Since online scanners primarily rely on cloud technology for the processing and interpretation of data received from virus scans conducted by the client program, it’s no surprise that a lot less processing capacity is required for keeping computers safe and secure. The only time your local processing power is ever needed when using online virus scanners is when the actual scan is being performed and data is being sent to the web service for further processing.
Since the client program is generally considerably smaller in size than traditional antivirus software, the amount of available hard disk space required for online scanners is also far less than what is needed for traditional antivirus software. Additionally, when using online scanners, you can also have real-time data sent back to the desktop in order to automatically update blacklists and prevent access to files and sites that could potentially be home to malicious software including viruses instead of waiting on manual updates by users.
Online scanners are also generally cheaper than their traditional counterparts, which is another important reason why so many people opt for cloud-based antivirus. Additionally, since they are based on technology that is new, online scanners are generally a lot more effective and productive than traditional virus scanners, and are able to keep computers and devices safe without any problems.
Relevant features such as reporting, file removal, scan scheduling, and virus scanning also come as part of the package with online scanners. This makes them a highly efficient and effective option for the majority of users.
