Win 8:
while at mail program (i think -now not sure) suddenly rec'd popup from Windows Defender(?) (showing as 'defender') listing some ''possible potential' threats that could crash my system & a choice to have 'defender' fix the problem(s) -- i know Windows Defender is turned off when another security system is installed - could that popup have been legitimate ? Do these false things happen? i closed -out -did a full system scan -nothing found - also did a Super AntiSpyware scan -no problems showing other than a few 'cookies' .. i'm confused ! thanks so much
