Perhaps
the spyware was installed prior to MS antispyware being installed ! Either way this program was running in the taskbar (little red target) when I scanned the system and found all those spyware apps.... Every thing from alexa (that windows update installs) right through to cool web search, Thousands of them !!!!
I still find it amusing that microsoft could produce a peice of security software when they cant even secure there own servers properly
Each to his own but you wont see me installing it !!
