Windows Defender Not Disabled
I want to know one thing..i have installed Norton Internet Security 2009 on my vista os with sp1 and all updates softwares and OS, now my question is why windows defender is not disabled if i have installed NIS 2009. However windows defender icon is not showing in taskbar but when i click on start, programs, windows defender it opens and when i click by going through control pannel, it opens..so if i have NIS installed will this defender would clash with NIS or not???...as i have heard we should not keep more antivirus and spyware in one system...plzzzzz guys tell me the solution!!!!!!!!!!
