McAfee running Pavilion CPU at nearly 100% takes laptop a long time to load anything

[OldManPC]

A Windows 10 update was preformed on this laptop about 2 weeks ago. since that time the computer is running very slow.

and sometimes is non-responsive. I openesd task manager whitch took an hour once. the longer the computer runs the slower it gets. In task manager Processes shows macafee running  the CPU at or near 99%. Lowest I saw when monitoring it was 75% and that was constent. How do I get rid of McAfee????  also the windows start menu will not come up when clicked or when windows button is pressed. I have tried to open the task manager and get this errior message: "FAILURE to display security and shut down option. the sign in process couldn't display security and sing in option CTRL+ALT+DELETE was pressed....."

I requested task manager about 90 Minutes ago it began to come up the window opened was there about 15 minutes with nothing on it except Task Manager and File, Options and VIEW. Then it show NOT RESPONDING. It finally came up and showed the processs with McAfee in first place with 98.8% CPU usage. I can't even off load personal files becasuse nothing will open up.

Welcome to HP Forums,  

This is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂

I see that your laptop  CPU usage is high and the system performance slow,

I would like to know the following information to assist you better:

• Is the laptop's performance slow while working in Windows?

Meanwhile, I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Open ‘Device manager’ and ‘Scan for hardware changes’.

Adjust your Windows 10 for the best performance:

• Right click on “Computer” icon and select “Properties”
• Select “Advanced System settings”
• Go to the “System properties”
• Select “Settings”
• Choose “Adjust for best performance” and “Apply”.
• Click “OK” and Restart your computer.

Disable startup programs:

• Hit Win Key + R
• Type ‘msconfig’ and press enter
• The Task manager window will open. Click on the “Startup” tab and you will see a list of programs that run at startup.
• Right click on the applications that you don’t want to run at startup and select “Disable”.

Defragment Hard Drive**bleep** Win Key + R:

• Hit Win Key + R
• Type “dfrgui” and press enter
• In the new window click on the hard drives you want to defragment (Prefer the drive in which Windows is installed)
• Click “Optimize” and follow the instructions on the screen to finish the defragment process.
• Restart your computer.

If the issue still persists and the laptop's performance is slow then I suggest you to follow the steps from the HP troubleshooter guide. These steps help in improving the laptop's performance. 

Hope this helps! Keep me posted for further assistance.
