High Fluctuating 100% CPU usage, possible virus?

[dylanj1]

My computer's admin login profile could not be loaded. So i made a new user profile which i use now, not too much of a problem. But after doing this my CPU is suddenly fluctuating massively from like 14% to 100 depending on how much is open, before i had the problem, my computer could run programs such as discord, spotify and chrome all whilst running a game of fortnite, csgo or something. My cpu is an Intel i5-4590 3.3GHz.

Have you tried checking which process is consuming that much CPU usage? Ctrl+Alt+Sup > Task Manager > Performance.

When I have no game open it fluctuates from 14% to 70, chrome being the process using the most of the CPU but when I have a game open the CPU usage is constantly 97 to 100%, with the game having the majority

Also, I use windows 7 so I don’t know if that will have an effect on things

Normally a corrupt user profile combined with high CPU and/or HD usage indicates infections(malware/rootkit/virus). You are going to want to boot into Safe Mode w/ networking and run the following:

NOTE: before proceeding with any of the below items, it's a good idea to clean out your temporary files first. This is a good app to do so: http://www.geekstogo.com/forum/files/file/187-tfc-temp-file-cleaner-by-oldtimer/

Adwcleaner: https://www.malwarebytes.com/adwcleaner/
ESET Online Scanner: https://www.eset.com/us/home/online-scanner/
RogueKiller: https://www.adlice.com/download/roguekiller/
TDSSKiller: https://usa.kaspersky.com/downloads/tdsskiller

It's suggested to also run either(or both) Malwarebytes: https://www.malwarebytes.com/ & Superantispyware: http://www.superantispyware.com/
(perform full system scans with them... usually Malwarebytes will pick up a few things that Superantispyware doesn't(and vice-versa)

Afterwards, it's a good to check out what apps are attempting to load with Windows. Windows could be trying to run corrupt/missing items that could be problematic. It's also good to see what actually is set to startup with Windows. For this, I suggest using:
Autoruns: https://www.bleepingcomputer.com/download/autoruns/


Finally... once all that stuff is out of the way, it's a good idea to also run:
CHKDSK: https://neosmart.net/wiki/chkdsk/
SFC Scan: https://support.microsoft.com/en-us/help/929833/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system


Enjoy!
