Whenever i power up my PC. I get a blank window that pops up which i cant move, close, or minimize. The taskbar says it is a devldr window. What the hell is devldr. At the same time, windowx xp firewall pops up and says a connetion was blocked. but i cannot chose to allow access or continue to block....its like it is frozen. anyone see this before? i have spyware and virus scanning on my pc, but nothing was detected.
