I recently had to buy a new computer, which came with windows 8.1 On my old computer, I used Microsoft Security Essentials, and was very happy with its performance. I found the following post by Bleeping Janitor in another topic (I hope it's OK to copy it to here):
"Windows 8 integrates Windows Defender on Windows 8, a more robust version of Windows Defender (and uses that name) for its anti-virus and anti-malware protection. Although it uses the same name, it is not the same as Defender in previous operating systems. Windows 8 Defender provides the same level of protection against malware as Microsoft Security Essentials (MSE) and uses the same daily virus definition updates. Since Windows 8 Defender includes anti-virus protection, it may be disabled by the installation of a third-party anti-virus program. Windows 8 Defender will remain disabled until the third party anti-virus has been completely uninstalled and then Windows 8 Defender needs to be activated if you choose to use it."
My new computer came with McAfee Livesafe preloaded. I understand I need to uninstall it before I can turn on Windows Defender. Will it be enough just to go into the control panel and uninstall MacAfee Livesafe? Thanks Andy
