Svchost.exe in Task Manager causing high CPU usage

Recently I have gotten this unnamed process in Task Manager that when I open its file location, it takes me to my sysWOW64 folder to the svchost.exe file. I get high CPU usage only when Task Manager is closed, and normal CPU usage when it is opened. I am sure that this isn't a igfxupdate.exe thing since when I ended the unnamed svchost task and close Task Manager, the problem didn't exist anymore. Of course, after about maybe ten or fifteen minutes it comes back. My Google Chrome has also started to randomly get suspended in Task Manager but I don't know if those two are related. I have used the programs SUPERantispyware and Trojan Remover but neither of them solved the problem or detected anything regarding svchost.exe.

I am not sure how to fix this issue. Is there possibly any way to fix it?

svchost.exe is a normally occuring windows process, HOWEVER, it is also a process easily hijacked by malware, so I'd agree this is an infection and I've seen the svchost.exe process infiltrated with many instances of the process in the past.

So, I'd start with Malwarebytes free scanner. Nothing there? Move on to Malwarebytes anti-rootkit.

Still nothing, move on to TDSSkiller.

Then Rogue killer.

Finally, just for good measure if nothing comes up in any of those, it's probably worth a shot to run the built in Windows defender scan.

If you still have problems after that, you might as well just do a clean install of Windows.

I have tried everything up to the Windows Defender scan. That seemed to have solved the problem for now.

Thanks!

Good deal. Bottom line though is that some malicious infections are just not able to be erradicated, and if you get one of those then about the only thing you can do is a clean install of the Windows operating system. It's the only guaranteed way to get rid of any malware or virus, permanently. Well, even then it might not be permanent, if you are not mindful of where you go, what you do, what you allow and what you open. In some cases you don't even have to DO anything wrong to get an infection. Just visiting the wrong web page can do it sometimes. Good luck though.
