Hi guys, This is what happen: I already installed Smart Security 4 in my computer. Thought, I installed the version for Windows Vista in my Windows XP system. It was a mistake. Big mistake, because after that, when the machine restarted, everything got frozen (all the icons), except the arrow of the mouse, but everything appears on desktop, but I cannot open. I tryed to put on the safe-mode, and tryed to make the restoration of the system to a day before that, but the PC don´t respond after restart. Please, guys, give me some help! I did that in a PC of a friend, not in "my computer" like I said before.
