Computer slows down after large files

Hello, I am running Windows 7 x64 and my computer drastically slows down after opening or transferring large files >1GB. If I reboot the system everything is fine again. Any ideas?

It sounds to me like file caching is pushing some stuff out of memory which then has to be read back in off disk again the next time you use it. How much memory do you have? It may be that adding more will help with this.

What sort of programs do you normally run, and how much memory is generally used when you run them? (as shown by the "Performance" tab of Task Manager - use "Shift+Ctrl+Esc" to start Task Manager)

Kaspersky Internet Security, Soundblaster, Chrome and LCD program for keyboard. My computer has been on all day and it says 1.91 GB used.
