Email removed for privacyi've got a problem trying to install Windows Defender.i was asked to uninstall Microsoft Client Protection.pls,what is it?1 person needs an answerI do too

What antivirus program do you already have installed? It sounds like you may have Microsoft Live OneCare or Microsoft Security Essentials. Both of these programs will not permit you to install Windows Defender since they already have their own antispyware components.Microsoft Security MVP, 2004 - 2010
