hello all maybe you can help.

ok my computer will boot fine, but when it comes to scvhost MS C++ runtime keep coming up with errors saying that it has asked it to terminate in an unexpected way. my system is clean when it comes to viruses (Avast, Norton, f-prot and the vrius scanner in Sytem suite 5 (ss5), no viruses)and the last thing installed was system suite 5, as a last ditch effort to get my sytem running, as the taskbar and *only* the taskbar would freeze as i logged in to the system. causing me to have to kill explorer and restart it or another shell (Litestep) now since i installed SS5
i get the error and have to wait five minutes untill i can hit hte ok button and the error goes away.
can anyone tell me whats going on?

heres whats in the error box:

Svchost.exe has asked microsoft VC++ runtimes to terminate it in an unexpected way. please contact the applications suport team

it goes away after explorer stablizes and clicking "ok" removes the message box but i have to restart the computer to allow anyone else the chanse to use it and they have top go thru the same thing

i could realy use a fix , or suggestion besides : REINSTALL, because its to much of a pain to backup 60 gigs on a unstable tempermental system.

thanks

Hello! I found this page while searching in google. I think its a lil bit repetitive, but i just have the same problem :/ I got installed the service pack 4 for win 2000 pro but i dont know why this app gave me problems (while installation and after). When the program is terminated by windows, my lap does NOT crash at all, but i cant go paste and all the problems metionated up there. With the only difference that it works like "normal" no sys crash, no internet or network connection problems, and no automatic restart... I dont know what to do, i was trying to uninstall the SP4 that i just downloaded and then re-install it once again, but in the control pannel/ software is a bug, i cant see whats in my lap installed, or the programs that i can use (and so on) why? how can i uninstall and reinstal this sp4??? I was thinking to reinstall all the OS but its a lil bit... u know... burrying :-P

hey ya'all! ..dude i got a serious problm here..i have this "svchost.exe"(network service) running and hogging up all my cpu processing speed..and im totally aware of the scvhost virus and adaware..i use norton 05 with updated definitions and im using spybot,adaware and spysweeper..now i have nothing detected!..and i dont know why it does that..but when i kill that process the service restarts again and everything is normal but when its running i cannot even open a single program..i can really use some advice here guys cuz i re-formatted and i still got the same probs..do u think its created by the windows sp2 firewall maybe?,or msn 6.2? cuz i get that thing stuck sometimes too, anyways help is appreciated ,thankx

problem - cpu 100%

solution - go to "run" - tipe there "msconfig" - than go to "services" - turn off "DNS Client" - restart comp and that's all

Hi,
I have had similar problems with SVCHOST.EXE Network Services hogging cpu at 100%, cleaned out all spyware trojans etc, but no better.
Then read Damir's advice here, and Bingo, problem solved, many thanks

No dice on the `DNS Client' shut off in my case. You cannot disable that when you have to use IPSEC. The system I see the problem on runs VPN client software, therefore needing the IPSEC functionality. Any other ideas?

Guillermo, put msconfig , not msconfig. .
Ok I disabled the DNS Client and the number of running SVCHOST.EXE went from 4 to 3 but 1 of them (the one that runs 20 odd services) STILL takes up 99% of my CPU.

Do you really mean svchost? You DO NOT delete it. It's a required system component. This article addresses that: http://ask-leo.com/can_i_delete_lsassexe_svchostexe.html

I had trouble with maxed out CPU due to svchost and lsass processes. the box (which is a pretty slow one anyway) was taking up to 15mins to log in, and was running like a dog before I killed the svchost instance that was causing the lag. In my case it turned out to be a remote assistance request that was trying to reconnect at boot and being blocked by security policies (hence the lsass). Disabling remote assistance through 'my computer->properties->remote' solved the problem for me. Just thought I'd post here as it's not something I'd normally of thought of, I got onto Microso... no I can't say it, and they were actually helpful! Bless 'em...

I'm posting this comment just to thank you for the excellent article on this "svchost cpu overuse" problem, and especially for LeighB pointing to Damir's simple and elegant solution, which fitted perfectly in my case, where there was no spyware or virus problem but a buffer overrun kind of problem. It has been a braincracker for me this past days and you all really supplied the help so much needed, thanks again.
