After running HijackThis.exe, i attach log files before remove and after i remove thing from windows running processes. But i sure the thing i remove need to re installed later. Before Remove : After Remove : The program that i suspect that cause memory leak is EMS FREE SURFER COMPANION. The program function is to stop pop-up and clean all website cookie and clean the recycle bin. The program start every time i close the internet explorer. Using msconfig, it only disable from the list and not remove from the list. I use startup control panel, much easier. For the virtual memory, 1.5X to low. I use 2.5X-3X of ammount ram installed. I fi can get more memory, but the problem is i have 20 Client pc and the worst is i use RDRAM. No Stock. Windows XP are not so good for cyber cafes. Always dead blue screen, when u update image files<Norton Ghost>. I need to add and remove games every month.
