Lately I've been having issues with my cpu usage going over 50 % and staying there, it just starts out of nowhere and I'm unsure what's the issue... Though i think it might be related to ''iusb3mon'' executable.

Most of the day it's normal and then just starts going like that and then I'd restart my pc and it stops. Happened once a day last two days...

Here are the shots of the processes when i restarted the pc and about a minute later. You be the judge.

I've installed MalwareBytes and ran a scan, it didn't find anything. Also I've updated Avast to the latest version and ran a Smart Scan, it didn't find any viruses... Only some performance issues that need optimization, which i can't do unless i buy a subscription.

A little added information may be helpful. The task manager images you sent showed no program using CPU, when your CPU is under high usage what program(s) in task manager are actually using CPU? What operating system are you using? Windows 10 has had some varying problems with Runtime Broker using up a lot of RAM or CPU at times requiring a clean install to totally solve (there are other "solutions" but for total system stability and to really solve it a clean install is the way to go).

You may want to also try running Malwarebytes in custom scan mode, selecting the drive your OS is installed on (usually C) and doing a full scan of the entire drive. Usually smart scan is enough, but sometimes you have PUP (potentially unwanted programs) that can cause a drain on resources that aren't found doing the smart scan.

I noticed that one of the ''svchost.exe'' processes was going crazy (there was around five of them running i think), I'd say that was the one draining all the resources. As when i checked it later it wasn't like before.

Best place to start is to ensure you have no Malware. If you don't already have it download Malwarebytes (from official website), install it, update it, and then select custom scan. Choose the HDD where you have your OS installed (usually C) and run. This will scan every file in your hard drive. It may find Malware, will probably find PUP (potentially unwanted programs) remove everything it finds. Reboot your computer and see if the problem persists.

If you have already upgraded to Windows 10 it may be a good idea to back up important information and do a clean install. I can walk you through the best way of doing that if you have upgraded but haven't done it yet. When you upgrade a lot of stuff from your previous OS comes along for the ride and can cause conflicts. Always best to do a clean install with a new OS (but you have to have upgraded through Windows Update first so your license is carried into Windows 10).

You can just reenter your product key when installing it from a disc or USB as well.

You know I remember having this issue on one of my older Windows 7 builds.. I think what I ended up doing to solve it was doing a fresh install of windows.

Although there is the possibility that it could be a Rootkit. In this case download TDSKiller, and RKiller and run both.

Sometimes noting will beat doing a clean install. I ran Windows 7 on my personal PC from its release date till upgrading to Windows 10. During that time I probably clean installed Windows 2, maybe 3 times (although at least one of those times was because I upgraded my motherboard). The longer you use an OS the more messed up your registry gets, the more temp files you have laying about, the more old useless drivers and fragments of programs, the more "garbage" you get effecting your system's performance. There are cleaners and tools to help keep a system "cleaner" but nothing does the job as well as a clean install. Just make sure your important files are backed up first. You'll also find that you aren't running as many programs as before (ie you have to reinstall everything and will think to yourself I don't play this game anymore or run this program hardly at all and won't bother with reinstalling it freeing up more resources). The nice thing is after a clean install its like having a new computer again. Everything loads quicker, they system runs smoother and on average most benchmark scores are better (until things start getting cluttered again).
