For some reason my friend's computer is showing that svchost.exe is slowly increasing in the memory usage. It's only 1, and it would go up slowly over time, eventually resulting in lag.

We used tasklist /svc, and there's 1 with a lot of services running:

audiosrv, broswer, cruptsvc, dhcp, dmserver, ersvc, eventsystem, helpsvc, lanmanserver, lanmanworkstation, netman, nla, schedule, seclogon, sens, shellhwdetection, srservice, tapisrv, termservice, tehemes, trkwks, uxtuneup, w32time, winmgmt, wuauserv, wzcsvc

What would be the cause?

Thanks in advance.

Yes; did a few scans for virus and spyware, more than once. It still seems to go up, after a while.

svchost.exe are "wrappers"...its a small program that controls other process's or services


What is a service wrapper ?
For a service to operate it has to present a certain interface to the operating system, f.ex. so the service can be stopped and started. The implementation of this interface is very similar for many services, so to minimize the size and complexity of the actual service it is placed inside a service wrapper. The service wrapper also saves resources by only using a single proces to have several services running.

When having problems with a service wrapper, then it is usually caused by one or more of the services running within the context of the service wrapper.....
Which service wrappers exist ?
Some of the common service wrappers, which can be seen in the Task Manager:

* Services.exe : Services Control Manager for system services.
* Lsass.exe : Local Security Authority SubSystem for security services. More Info MS KB Q308356
* Svchost.exe : Service Host for loading dynamic-link libraries (DLL) as a services
* Dllhost.exe : DCOM DLL Host Process supports DLL based COM objects. (Replaces Mtx.exe)
* Svrany.exe : Applications as Services Utility

you may have to do a repair on windows...maybe someone has a easier fix so lets save this for last...

Hmm did you scan it with an antivirus that was installed on the same computer? 99% of the time antiviruses get knocked out by the virus and make it useless. Use a free online scanner ( http://www.pandasoft...ACHEHINT=Guest# ) or remove the hard drive, place it in another computer as a slave device and use the antivirus on that computer to scan it. If that fails then yeh you may have to do as happyrck suggests
