It been awhile since I've done a complete PC scan. So selected Mcafee icon lower right tray, open Mcafee SecurityCenter. Mcafee opens, then into scan and selected full PC scan. Nothing happens, Mcafee freezes up. Tried several times. The only way to get out is Task Manager>mcafee>close program. I have found other tabs within Mcafee also not working. Using Windows 10.
