Hi guys and girls . I have recently tried to install windows defender and it keeps getting hung up on the windows installer screen. Seems like the download is good and everything. I also did all the vaildation crap that windows does, so i dont think its the OS. Any suggestions? Do i even really need it ? Any other good ones out there? I use ad-aware SE personal now and i only browse with Mozilla firefox. Any thought or help would be much appreciated.
