I recently clicked on a link (mattm.powweb.com/?****… where *=letters & numbers). When I opened the site in IE, it closed the window after a second. When I restarted my computer, it said that a program called "null" did not end. I hit end task and it restarted. Everything seems to be running fine, but here is my HjT log just to be sure.
