svchost.exe taking up 50% of my CPU (windows 7)

[Anjroo]

https://gyazo.com/5cd9cac26874427dc1af3c996e990eb1 A process called "svchost.exe" is taking up around 50% of my cpu.

Whats funny is a couple days ago my computer was just fine, I didn't even download anything since then.

I searched for rootkits and malware, restarted my computer and last time I disabled the process (and restarted my computer), it didn't help and I think it was screwing up my computer so I did a system restore, but the problem is still there.

Could someone please help with this?

Thanks

svchost.exe is just a name windows gives to a program that it really has no name for but it internet related. In most cases it is a malware but it can also be like windows updates running in the background.

 

Do a malware scan, if you find nothing, just right click the process and say end then do a restart and see if it returns.

I did all that and it came back after restart.

SVCHost isn't really a specific thing, it's just a background process. Service host. A process that hosts services. It manages audio, apps, updates, ect.

 

Win Key + R ---> resmon

 

It'll open up the resource monitor, which will give you a much better idea of what exactly is using this processing power. It'll allow you to look into the svchost process and see what it's actually doing so that you can track the issue down.

Well I have this problem too. Disable wuaserv.exe in your services and you should be good for a little while. Sometimes though, it'll take up half my RAM on idle, so don't expect this to be the end of your svchost problems.

What did you use to do the scan with?,,,,and Jesus H. Christ, don't tell me it is Norton/Windows Defender/McAfee.

 

Check windows update and see what is listed as available updated if you see anything then do the updates if you want or you can just right click them and say hide. 

 

These are quite hard to diagnose as it can actually be a legitimate windows process executing in the background.

I scanned with malwarebyts and rkill, but that doesn't matter because disabling it with cmd worked.

You shouldn't have disabled it because it is windows update and you should leave that to run and choose what you want to update but if it works for you then cool.

Just set windows update to "never check for updates". You can manually search whenever, so this doesn't do anything bad. No need to disable the service entirely.
