You're here because you've been "infected" by the ym_snot "trojan". You'll 
notice that it changes your Yahoo Messenger status message every few seconds, 
probably to something gross :).
Here's how to get it out of your system quickly & painlessly.




1. Open Task Manager, go to Processes. Make sure the User Name column is 
activated (if it's not, activate it from View -> Select columns.
2. Find the "svchost.exe" process running as your windows username, NOT as 
SYSTEM. The one(s) running as SYSTEM are good. Hit "End Process".
3. Hit Start -> Run and type "regedit". Go to HKEY_CURRENT_USER\Software\
Microsoft\Windows\CurrentVersion\Run and delete the key "braaainz"
4. Go to your windows directory\system32\drivers\ and delete the svchost.exe 
file there. Just the one in the drivers folder, not the one in the system32 
folder.
