After that the computer suddenly goes unresponsive. It takes over a minute to respond to clicks. Task manager indicated that CPU usage is low and Disk activity is low. It just puzzles me.
Nothing I do could solve the problem. Manage to get Win 10 to boot to safe mode by forcing it to close then start again 3 times.
Even at safe mode, it also responses not that well. On searching from internet, it was suggested to check page faults. Starts Performance Monitor and adds page fault. The percentage is 100. Netizens suggest using Sysinternals, Process Explorer. Downloaded it and run. There is an item that has more than one million page fault. It is Mcafee.
Uninstalled it and the system works as normal. One problem still persists. Windows Defender antivirus shows that "the virus protection is managed by other manager". No facility to set it back. Well, that is not part of this issue.
