Hi,
i have been a bit of a donut. My PC contracted the virus XP Security Update 2011 and so i did a bit of research on the net and having found something i thought would work I deleted a few registry files, only really HKEY_current_user Software Classes .exe .....i rebooted my PC, it seems to have done half the job in that this virus hasn't appeared, and if i try to load anything off desktop/start menu it loads. however all the software that usually loads when i boot up doesn't boot up any more, and i can't get on the net. Even weirder if i go into that same registry there is nothing under .exe
any ideas how to restore this? i am a real idiot for doing something i literally had no clue about...
