Private Working Set is perhaps a more accurate indication of how much physical memory the process itself is using, and is also the default memory column for Task Manager in Windows Vista/7/8.

This is only the the amount of memory in use by the process itself and isn’t shared among other processes.

Private Working Set – Is similar to Working Set, but excludes the shared memory.

This is the default memory column in the Windows XP Task Manager. It does though represent the maximum amount of non virtual memory in use by the process. As such, this value isn’t truly accurate because shared memory can be double counted due to the same resource being registered in multiple processes.

Working Set – This is the amount of memory used by the process PLUS the amount of memory that is shared with other processes.

The two memory readings we paid most attention to were “Working Set” and “Private Working Set” (WS Private), which do two things: A problem with taking memory readings is there are several different numbers you can look at.

To find out just how much memory gets used by running antivirus software, we’ve decided to gather together a mixture of 25 popular commercial and free antivirus packages to see how they perform.Īs you might expect, testing an antivirus product for its memory usage is certainly not an exact science because the program is never standing still and nearly always doing something in the background. But if your computer isn’t the latest and greatest, using a package which might possibly be eating hundreds of Megabytes of system memory could slow your computer down considerably at inopportune moments.

It’s maybe not such a major issue for newer computers these days having an antivirus which isn’t especially memory efficient because they often come equipped with 4GB or more of RAM. Have you ever wondered which are the lightest antivirus packages available and which ones don’t do so well on memory usage? One of the most common applications that will load with Windows and stay resident in the background while the system is on, will be your chosen antivirus software. Having just a few memory or processor hungry programs loading into the system tray on boot can have an adverse affect on the performance of your computer.

One of the most common things users do to try and keep their computer running as smooth as possible, is keep control over which programs start with Windows.
