Advanced WindowsCare Personal 2.5 doesn't mention anything about antivirus or a firewall in it's description, only spyware protection. It also doesn't mention the ability to backup your data. Those are some of the foundations of Windows Live OneCare, so I would not consider then competing products...Advanced WindowsCare Personal 2.5 just doesn't seem to have the security aspect to it.
Now, while Advanced WindowsCare Personal 2.5 is compatible with Windows Defender, note that OneCare has Defender integrated into it, so you would not want to install Defender on top of OneCare.
Perhaps if you detail exactly what you're looking for we can offer some suggestions?
Hope this helps,
Would this be a better option thant Micro Live One Care? It has continued to give me headaches!
And would It be compatible with FireWall Windows Defender that is included in Vista HP? Have HP Pavillion m7750n Media Ctr.PC.??
