When using ms AntiSpyware and CounterSpy on a much abused pc lots of infections were discovered. However both scanners eventually grind to a halt. Counterspy stops at the registry scan on file No.12158 and ms antispy stops on a registry file 8336,HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\WinTools. PC is P111 733 mhz. 256mb memory, bags of hard drive free. Spybot doesn't even get close can anyone help please.
