I have noticed that as many times in the past few weeks I have received notifications from Windows that Virtual Memory is low and had to be increased. I was wondering what might have caused this. It seems to happen when I am using Windows Movie Maker, and only since I downloaded some Movie Maker Updates one of which i installed and is a compilation of Video Effects. Could this be the problem, I have scanned several times and Spybot has turned up Cool WWW Search and I have instructed Spybot to fix the problems. Could this be the problem? What other forces could be at work requiring Virtual Memory to be increased and can the operation be reversed later when the problem is solved.
