Preventing Crashes

The World's Smallest Non-Conflicting Agent

Webroot SecureAnywhere® is a 700KB client that has been architected to avoid potential conflicts with other software – including other security software. This allows administrators to confidently deploy Webroot SecureAnywhere into any environment. This eliminates the need to uninstall pre-existing security solutions prior to migration and also allows for a multi-layered security approach if desired. It maximizes security and productivity by never getting in the way.

Antivirus scans and updates are usually the reason why customers using legacy security software report their machine is running slowly or they can't use a machine at all during an update. The CPU and RAM usage is so high that many machines don’t have enough resources to run the users’ applications.

The Webroot SecureAnywhere® Agent is an ultra-light endpoint client of 700KB, designed to provide a significant improvement in operational speed. On disk it occupies a mere 4 MB* of space and during scanning its RAM usage is around 12MB* or less.

Once Webroot is installed, you don't need to do anything - it's more streamlined and user friendly.

Due to its small size and design it operates efficiently on computers with minimal system requirements. Recent independent testing of all the major antivirus vendors by PassMark Software has clearly shown that Webroot SecureAnywhere is by far the world’s lightest, smallest and most efficient endpoint protection Agent.

Webroot SecureAnywhere typically downloads and installs in less than six* seconds, and is fully operational in under *2 minutes.

When deploying an antivirus solution, you often need different client Agents depending on the class of machine where the install is taking place. This is not the case with Webroot SecureAnywhere. You use the same Agent for deployment on PCs, Laptops, and Servers or in VMware, Microsoft Hyper-V and Citrix terminal server environments. The unique capability to intelligently tune CPU and memory usage when resource-intensive applications are detected allow the Webroot SecureAnywhere Agent to be installed within individual virtual machines or on task-specific servers without impacting their performance. This feat is impossible with other AV security vendors’ software because of their large footprints and demands for CPU, Memory and Disk resources, which are often hundreds of times bigger than Webroot.

Our lightning-fast system scans take under two minutes, compared to hours for many other security solutions, and the ability to run concurrent scans allows Webroot SecureAnywhere to effortlessly scale to thousands of Virtual Machines on a single physical server. Webroot SecureAnywhere achieves this by scanning beneath the operating system and parsing the hard disk and registry at a raw level.

Webroot SecureAnywhere is designed so that it can coexist with other security products and play a complementary role in a multi-layer security approach; eliminating the need to uninstall existing solutions prior to migration. It maximizes security while not getting in the way of endpoint performance or user productivity.


With the Webroot SecureAnywhere® Agent, there are no local signature definition updates, so user productivity is never impacted by recurring updates.

Our light impact on system resources also means that Administrators can schedule regular security scans during the working day without impacting the user’s ability to use their machine; something that’s impossible with most other solutions.

Definition Updates ‘In the cloud’

Usually, there is a lot of management involved but this is much simpler. Now, it’s just automatic.

Webroot SecureAnywhere maintains all threat updates at the cloud level within the Webroot® Intelligence Network, so every Webroot SecureAnywhere user world-wide is instantly protected at exactly the same time.

This collective approach has several substantial benefits that turn into significant cost savings in person-hours, hardware, software and bandwidth.

Most importantly from a prevention and compliance perspective, every user is continually up-to-date when they are connected to the Internet and at the greatest risk. However, separately configurable Offline policies ensure they are fully protected when offline too.

There are now no operational risks such as ’blue screens’ due to a corrupt definition updated and the unplanned compatibility changes they may produce. Network bandwidth is also minimized, as there is no longer the need to distribute large definition update files that can consume 5MB+ per day. Plus, IT saves time thanks to never having to test and administer new updates. There is also no need to maintain or pay for any on-premise servers dedicated to AV signature definitions.

Eliminating definition updates represents a huge advance in the design of antivirus technology and one that is unique to Webroot SecureAnywhere.


The Webroot SecureAnywhere® Agent is an ultra-light 700KB client designed for significantly better operational speed than other AV solutions.

On disk, it occupies less than 4MB* of space. During scanning, its RAM usage is around 12MB*or less.  It is by far the world’s lightest, smallest and most efficient endpoint protection Agent.1

Webroot succeeds where other solutions have failed, with a smaller footprint and faster scanning. It’s an easy-to-manage, time-saving product.

The Webroot SecureAnywhere Agent works by sending file signatures and ancillary data on programs and objects to the Webroot® Intelligence Network. It then receives real-time predictions and determinations on whether an object is ‘known’ good, ‘known’ bad, or unknown/undetermined.

Independent Benchmark Testing Confirms Our Outstanding Performance

The reduction of on-device processing directly contributed to Webroot SecureAnywhere scoring a record 78/80, or 97.5%, in independent performance testing. These tests focused on different performance metrics determined by PassMark Software and  compare Webroot SecureAnywhere to seven of the world’s leading AV vendors.

Webroot SecureAnywhere uses a variety of techniques to reduce the impact it has upon local endpoint resources. These include parsing the disk at the RAW level (to maximize scan speeds), minimizing network communication and intelligently tuning its memory usage when resource-intensive applications are detected. This feature is especially useful in traditional and virtualized server environments as well as on PCs.

During the most comprehensive scans, Webroot SecureAnywhere typically sends between 300KB and 2MB of data to the Webroot Intelligence Network for analysis. It normally receives back less than 250KB of data. On average, normal daily operation of the Webroot SecureAnywhere Agent exchanges less than 100KB of data with the Webroot Intelligence Network.

The result of optimizing Agent size, functionality, scanning, communications and interoperability within the endpoint environment is that it’s never obvious to end users that the program is using any CPU or RAM resources, and therefore never gets in their way.

Such low resource usage also permits Webroot SecureAnywhere to run concurrent scans, or effortlessly scale and run on virtual machines operating within a single physical server - without any disruption.

This low system impact also improves security, as Administrators may schedule regular security scans during the working day without impacting a user’s ability to keep using their machine; something not achievable with other solutions.
