If my PC is left on for several hours, everything grinds to a total halt. It stops me loading the Task Manager to check memory utilisation. I'm running AVS with Comodo and the other active background processes in the task bar are Windows Live Messenger and Netmeter. I suspect that this is a memory leak issue,and have a suspicion that AVS may be the root cause. However this is nothing more than a gut feel at the moment and could be totally unfounded. Is anybody aware of any memory leak issues with AVS, or even Comodo or WLM for that matter?
