Hi, recently the midddle system svchost.exe that uses the most memory has been using up to 25% of the cpu. It will just go all of a sudden often at least an hour apart, and use the cpu for a minute max. I have noticed that somtimes it does it when i have just connected to the internet, but not always. I have not had an event of it happening offline which I can recall. I have done scans with several apps, and they show no problems. This problem didn't happen in safemode.
I am not sure whether this is spyware, or somthing else, I have no idea about what it is or whetether it is ok/bad.

any help appreciated, thanks jake

While I defer to our security team for a double-check on your log
...25 % is not a lot.
Many system tools that run in the background-- could use that much.

Everything in your log looks fine .I see no problems.

ok, thank you ih8bills for those usefull links, I may disable a few unneeded services. Also thanks pancake for checking
I am looking at the services, and using the process xp program to look at all of the 7 svchost.exe instances, they all have information as to what they are. I didn't notice any unknown ones. I will try and find which threads are being used when the problem occurs.

thanks, jake

Your welcome.

yeah-- everybody sees that svchost thing and says "what's that" ??

Not all bad... if it starts using 100% ... that's usually when there is a problem.
It's good to be cautious ...and it takes a bit to learn what's bad-- and what's just normal.

NOTE: When configuring with Black Viper's guides-- everyone's system is different... so it takes some trial-and-error.
Windows will tell you if needed services are disabled for anything to run.

This is what normally happens.
When I turn on the computer wuaulct.exe is running off the main system svchost.exe, which I can see in
process explorer. When I connect to the internet another wuauclt.exe appears and the cpu is used 25%
with svchost.exe for at least a minute before I get a windows update pop up message
from windows update.

Only this in most cases seems to happen at a random time when I am not installing an update, and
the windows update tray icon isn't there. As far as i know wuauclt.exe is always there
when the problem occurs, and wuaueng.dll is the main dll being used at around 25% when it happens.

Now i'm not really sure but believe this may be happening becuase windows update had previously
downloaded several windows defender updates automatically but without installing them, which I did not install later and asked windows update not to notify me again.

So a few days ago I set the updates to 'notify me but don't automatically download or install them', and the reason for this is because whenever I install a windoews defender update using windows automatic updates a restore point is created named Software Distribution service 3.0
And with this happening every few days I lose hard drive space. So I now download windows defender updates as a file manually on a microsoft site.

So now I am thinking, maybe all of the updates for windows defender (and outlook) that were downloaded but not installed are slowing wuauclt.exe (windows update down),and perhaps causing it to use cpu at random times. i don't use outlook, so i wasn't don't downloading the updates.



I then asked windows update to 'offer updates that i have previously hidden', and svchost.exe
used to 25% (anolther wuauclt.exe ran, and wuaueng.dll was used) like all the other times lol.
It just kept popping up to install these outlook updates even though I was not downloading them and asked them to stop notifying me, they had different KB numbers for each but looked like the same file. Microsoft is probably recognising I have the software, but not the updates. So i installed one, and the problem has not occured since yet.
(in the screenshots the read and green '.msp' files keep showing and then dissapearing quickly loads of times for about a minute till svchost.exe has stopped using the cpu- even when updates are not being installed or downloaded)

thanks, jake
