it was my 10yrold little brother who downloaded some minigame and got the pc infected. he also clicked ok to any dialogue box that came and so there was this "antivirus2008" programme installed which i knew wasnt what it appeared to be. so i installed AVIRA and got half the porblem fixed.
other than reinstalling windows (which is currently not an opiton fo me right now) how can i restore stuff lost such as the task manager ("task manager has been disabled by your admin") and my startmenu doenst have buttons like RUN so i cant start msconfig but ican access control panel indirectly.most of the startmenu buttons are gone
