I had mcafee anti virus before, it worked just fine. After it expired, I purchased mcafee total protection and installed it. My laptop (windows 10) became running very slow, it takes up to 10 minutes to boot or take very long time to navigate / open any page.
I tried to follow the 2 links below but didn't help
Install and run the McAfee Virtual Technician (MVT) : it stated no issue found.
Reinstall the McAfee product by following the steps below (when uninstall mcafee, do both uninstall from control panel > program and feature, as well as run MCRP.exe tool
Note. When uninstall mcafee, my laptop runs very fast .
To begin with we'd like to which resource is being used the most, whether CPU or Disk or Memory.
Based on this we'll be able to narrow down the cause
Hi Selvan :
Thank you very much for replying. I opened task manager :
Right after rebooting : the most usage : Disk > CPU > MEM
Few minutes later :
MEM ( more stable at 33%) > Disk (0 to 50%) > CPU (3 - 15%)
