Hey Guys, I have been having some trouble from a particular type of spyware. It started when an end user clicked on an add by Win Antivirus 2007, I have been able to remove almost all of the infection except for a registry key. HKEY_LOCAL_MACHINE\SYSTEM\Controlset001\Services\Core. It will not allow itself to be manually or automatically removed through Normal Mode or Safe Mode. I have used Spybot S&D, Ad-Aware and Panda Active Scan. I have ran Hijack This several times and removed the entries which I can identify as invalid, harmful or missing. Please let me know which avenue to pursue. Thank you!
