F-Prot for Windows is easy to install and use. This antivirus program has a nice interface, although it would be more user-friendly if the options were available from the Taskbar instead of from the Start Menu or desktop. All of the options are straightforward and practical. Some of these options include right-click, on-demand, on-access and scheduled scanning.

F-Prot claims their scan engine uses very low system resources and therefore runs under Windows 2000, XP or Vista.

The RealTime Protector scans all files your system accesses for viruses. The built-in Scheduler automates tasks like updating the virus definition files and scanning. The program is simple to configure, but still gives you plenty of options. The on-demand Scanner is used to manually scan your files, folders and drives.

You can also scan a file, folder, or drive from within Windows Explorer by right-clicking and selecting "Scan". There wasn't much of a performance hit during normal PC usage.
