When i restarted my comp PC Cillin come up saying I have the virus TROJ_DLOADER.LE (Win32.Chisyne)(Downloader-ZM (McAfee)

It said the quarantine was unsuccessful, so I went to the site to see how to remove it. http://www.trendmicro.com/vinfo/virusencyclo/default5.asp?VName=TROJ_DLOADER.LE

It says to delete it at HKEY_LOCAL_MACHINE>Software>Microsoft>Windows>
CurrentVersion>Winlogon>Notify>{name of malicious (.DLL)}

I'm running WinXP Pro and I don't have the winlogin folder in my registry, it also says to delete it at:

HKEY_CURRENT_USER>Software>Microsoft>
Windows>CurrentVersion>Browser Helper Objects
In the left panel, locate and delete the key:
{8E13DDE1-E013-47ec-9C4C-27C2F78BDD26}

which I do have, but is it safe to delete it from the 2nd key if I can't find the 1st?
And would it be in another folder other then winlogin? My comp has been running slugish for the speed it used to run at, programs used to open instantly, now it takes about 3 x longer.

Should I just delete the infected file?

Trend micro says you can also do an online scan
http://www.trendmicro.com/vinfo/virusencyclo/default5.asp?VName=TROJ%5FDLOADER%2ELE&VSect=Sn

First download microsoft antispyware,

update it, and then run it, it found a trojan downloader on my system i didnt know i had, and i believe i have good security

Then try the online scan from trendmicro
