please be informed that after warning in AVG installation wizard is showed "Add or Remove programs" by Windows (from Control Panel) and you need to delete it (run uninstaller) by your own. If some files were deleted during Windows Live One Care uninstallation, please contact their support.
Else files recovery is possible through some special utilities available on Internet.
On Sat. 11/07/09 I tried to install the above subject. I am not computer savvy, so @ the end it said, I would have to uninstall "Windows Live One Care." I pressed ok, then a little black window opened & I saw (real fast) stuff being deleted. Well AVG didn't install & I lost my files...documents, pic, favorites, etc. My Windows Live One Care is not active, but still in my computer. Can you help me to recover my lost files?
