I like to run my system as smooth as possible, I don't like resident things, I like windows as lite as possible . Before I have acquired internet, only resident thing running in my system was windows itself . Now I have Outpost and NOD32. If I'm using Opera (I'm free from Explorer bugs), I'm not using POP3 and I always scan every file I download, is IMON important or I can leave it disabled? Thanks for the answer(s).
