I have Windows XP SP1 with Norton Antivirus 2004 Pro installed.
Some virus has come into my computer, which has blocked my regedit, folder option, noton antivirus etc.. etc... That restarts my computer within few minutes i start my computer.
I am not able to see Folder Option in both control panel and explorer tool menu. also when i open regedit it gives a message "Registry Editing Has Been Diabled By Your administrator".
I manally deleted some files(which were infected by the virus) in system folder first by first killing process in task manager and then deleting.
But still computer is still affected and i am not able to reinstall norton. What should i do??
