Hi. I don't know if this is normal, but NOD32 slows a lot down the computer when I'm navigating folders. Sometimes it takes up to 5 seconds to open a folder with some files and other folders in it. Other antivirus software slowed down the computer too, but it wasn't as slow as NOD32 when opening folders. The rest is fine (scanning, starting up, starting programs...) I'm running an Athlon XP 1700+, 734MB RAM, ASUS A7N266-VM nVIDIA nForce chipset, Windows XP SP2. Thanks!
