Hi, i have a trojan in my system. Norton antivirus detect the trojan in the file "c:\windows\system32\Crdb214o.dll" but it can't delete the file and display a message Access denied.
My account is member of the administrators group, i don't know how to enable to delete the file.
I'm using Windows XP professional version 2002 SP2
Go through these general malware removal steps systematically - http://www.elephantboycomputers.com/page2.html#Removing_Malware
Include scanning with David Lipman's Multi_AV and follow instructions to do all scans in Safe Mode.

The site is in German but David's tool is in English so don't let that worry you. Scroll all the way down to almost the bottom of the page and you'll see a box titled "Infos Zum Download - Multi-AV Scanning Tool". You'll see "Download von www pctipp.ch" and the live link to download Multi_AV.

When all else fails, run HijackThis and post your log in one of the specialty forums listed at the first link above (not here, please).
Standard caveat: If the procedures look too complex - and there is no shame in admitting this isn't your cup of tea - take the machine to a professional computer repair shop (not your local version of BigComputerStore/GeekSquad). Please be aware that not all local shops are skilled at removing malware and even if they are, your computer may be so infested that Windows will need to be clean-installed. Have all your data backed up before you take the machine into a shop.
