Windows 7: High cpu usage only while idle [generally after windows updates]

26 Aug 2010   #11

Windows Server 2008 R2

Well, not really - remember, WU scans aren't specifically reserved for WU; 3rd party apps can call the WU APIs and scan a system too, which is what is happening here, over and over again:

lve managed to get the threads part running so l guess l have to wait until something happens pin down the service then just wait.. as l cant work out how to do the logging trigger thing.


lm not totally sure yet but l think the issue comes from the svchost [local network restricted] also happens to be using around 104/113meg of ram, and seems to be the most active.. then again since its network l guess its obvious its accessing something because lm online, l shall keep an eye on things for the time being unless there is an easier way to get it to tell me whats using high CPU

It is happening because of bitdefender (look closely at my last post):
[ClientId = BitDefender Scan Service]

I don't know how that product works when it scans specifically, but it's obvious it's using the WU APIs from COM to scan the machine for *something* (I'm guessing to make sure you're current with updates???). Unless you can stop bitdefender from doing that, you are going to see this behavior. If you're unable to stop bitdefender from doing this, you might consider replacing it with something much more lightweight, like MSE.

if thats the case l dont get it because its not set to check that often, once every 24/12 hours.. however since the last post it hasnt happened again to my knowledge which is annoying as lm now monitoring the situation closely for a definite idea what is or isnt causing it.


since l still have 90 days on my bitdefender licence l took the issue over to them, got the usual recommendations tho l didnt realise my code was valid for the 2011 version, for the time being l shall test it and see if the same issues occur, if not then l shall know where the issues start, however if they do then who knows, regardless l shall bring them here after all someone might find this thread and interesting read if the problem is solved.
