As you work on your PC, 20-40 invisible processes run silently in the background(‘Ctrl+Alt+Del’). While most of them are vital, some may unnecessarily occupy system resources or worse yet may be a spyware or a trojan. For performance and security conscious folks I have created custom firefox search engine which uses tasklist.org as a base site and lets you instantly lookup ins and outs for any running process.
Check it out. Firefox folks can add it to the browser search engine list and afterwards access it directly from the search toolbar(screenshot below). As about IE users I can’t think of anything but to bookmark itself. :-)
