incorrect cpu usage values

Question

My pc wasn't like this when I was still on windows 10 it only happened recently as well task manager shows different cpu, memory, and other values incorrect in processes it already doesn't add up didn't happen when i was on windows10 then I checked on users I'm the only one there and it shows on mine 17% but the total shown above is somewhere 90% I've installed different anti-viruses to check and it showed no malwares I've also asked others that know a lot on this kind of stuff they said it was normal but I'm still concerned since my pc slowed down so much just even opening task manager takes like 5seconds and it used to be 1-2 second before so is this really normal? having triple the total of what you're using in your hardware?

Answer 1

yes i remove them after i use them

Answer 2

You mentioned you have installed different antivirus to scan for a malware. Were these removed after the scans or are they still installed? If not done already please remove them as they are the number one reason for an increased cpu consumption.

Answer 3

yes but it wasn't as bad as before the lag also decreased
