I have a fresh installed xp in my pc connected to a network.. and i forgott to disconnect it from the network while under installation process.. a trojan horse virus has infected me first before i've installed the norton 2007 systemworks w/ anti-virus.. that's why i intend to full scan the system for me get rid of it that virus.. and it was resolve and the virus was remove completely.. but the problem is?? the virus has change my xp system registry making it possible to create a Windows System Folders from my dirve C: like ProgramFiles and MyDocuments and DocumentSettings to be duplicated in the same location... and everytime i've created a new folder inside my drive C:? it always duplicated and once i've delete the new folder i've created? only one of the duplicate is erase and i cant erase the other because windows prompt me like this: "Can not delete file: Can not read from the source file or disk" "click OK" and when i intend to create a folder with the same foldername "PROGRAM FILES"?? then WINDOWS is restricting me to create a folder which already exitsing with the same name, and also the same with other folder besides from system folder inside drive C:\?? i know that creating folder with the same foldername in the same directory or location is restricted... but the troublesome is how's that happen that even i restarted xp i always see the duplicated folder of PROGRAM FILES and others system folder and also the new folder i've lately created.. even if run xp in safe mode or either command prompt safemode.. still i see those bunch of duplicated folders and i observe that those duplicated folder name is just something shortcut to the original folder... but even shortcut has different foldername or filename and they just the same on the target isn't it?? correct me if im wrong... im not good in XP OS trouble shooting specially when it comes registry editing but as of my openion theres something registry related here needs to be fix... correct me im wrong...
