svchost.exe

Post by toast »

Hey, all.
Some times when Im randomly flocking the internet, my computer freezes up. I pull up my task manager and its "svchost.exe". Its using 99%, and the mem usage is about 99,000K (Im estimating but I know it gets really up there)....
When I kill it, everything goes haywire and bounces back to normal.
My question is -why does it use so many resources? What is causing it?

~thanks~ Toast

:roll: svchost.exe has been a popular question by neos checking their processes. Do not mess with it. As long as the file is located in C:\Windows\System32 it is a part of the windows OS. It is a generic host processor for services to run. You can have several svchost.exe running, each controlling a service. If svchost.exe or scvhost.exe(note misspelling) is located in a directory other than C:\Windows\System32 then it is likely a trojan using a common windows process name to hide.

don't get too focused on svchost.exe (if in the the C:\Windows\System32 directory), your computer crash could be entirely unrelated.

You have the HP Pavilion laptop, it looks like you recently purchased (by looking at the results of hijackthis) The pavilion series is pretty good, a decent price range for a worthy chipset. If you have recently purchased this computer and it has not been working right since day one, it is likely damaged by shipping and handling. If the computer was working fine, but started acting up after you downloaded software, or even installed software via disk, or deleted any files, then it is likely software related. Back up all your porn and reinstall.

I have the AMD chipset sempron 2800+ Compaq Presario M2000, with almost the same software setup as you. The only time I have had crashes was trying to surf in IE (7.0 beta) and start AIM at the same time.
If it is a new computer you can at first try a reinstall with the recovery disk, or return it to the place you brought it (15 day return policy or else free checkup/repair). If you have to send it out for repair, save yourself some time and call HP yourself, they will send you a mailing kit, a box and padding to ship it back to them. I got mine back in a week (not this box). The best option is to exchange it for another brand new in the box.

I agree with DNR, there seem to be no real malware on the system, but A LOT of unneccessary entries, to make it short: you box is a mess... :lol:
either XP is running for a long time already or you test a lot of programs....so it's time for a new install imo, will be much less time consumpting than looking for the cause of the problem...and your system will be much faster afterwards too.... :wink:

p.s. when done you can post the new log and I'll tell you what services you should disable, there are plenty of apps on your system which connect to the net in the background....like the real player *yuk* ...you really should use media player classic instead, it can be found in the downloads here..simply search for Realplayer Alternative, it's free from spyware and plays almost any media file... :wink:

Okay, I repaired it (the os) not reinstalled it.
And it looks/ feels the same as before. Cept now I got a whole new error message.
I ran Hijack again and it looks the same as before.... (eh?)

Would you still like me to post the 2nd log?

a repair install is worth nothing because only the system files are replaced, all settings and the rest of the files (malware or not) stay on the system....so nothing has changed.
for example: let's say systemfile XXX is not working because some registry settings done by a game you've installed are messed up. now a repair install will only replace file XXX but the registry settings still stay corrupted and XXX will still not work.
backup all files you need to DVDs or an extra HDD and do a new install (a real one)....it's the only way to get a fresh and clean system... :wink:

So if and when I reinstall, my programs will be lost, correct? Like my firewall, anti-everything and so forth, will have to be replaced correct?

1 dollar for every time I have said this and I would be a rich man.... :lol:
I have to install XP twice a year (if nothing unusual happens), you'll have fun again when you notice how fast your system is after then new install....don't worry, that's normal... :wink:
