Norton Antivirus deleted svchost.exe

Try registering it:

Go to Start>Run

type or copy and paste: regsvr32.exe /s C:\WINDOWS\system32\svchost.exe

Click OK

I tried that but nothing seemed to happen when i restarted....i tried once running a new process with the svchost.exe file a few times but it only appeared in the list for a brief moment then disappeared in task manager. I think that when it got deleted by norton it made the file un-executable which might have to do with something with the registry because some programs(DLL's) run off of svchost

Then to save time, I would suggest doing a repair install of XP. You'll need your installation disk and your product key. A repair install will not affect any of your personal files but will restore the operating system files and registry settings. If you don't know how, then follow the instructions in this link http://www.michaelstevenstech.com/XPrepairinstall.htm

well i'm going to have to buy the windows xp installation disk but i'll just do another re-installation just to save time because i bearly had anything on the computer as it is anyways but thanks for all the help

Try the last thing I mentioned. Open a command prompt and run
svchost.exe -k rpcss

I'm having the same problem, but I got it through a fake link to a program I wanted..it was a virus called Antivirus 2008. I used a few of my antivirus programs ( spybot S&D, AVG anti-spware, and Ad-aware 2008) and it seemed to get rid of it but when I restarted my computer it did exactly what jayvon described. I don't have Norton installed either.

Heres my log just incase someone decides to help:

Delete everything below using Hijack This. That should solve most of the problems but you still might have to replace the svchost file. You copy it or download it. Also, I don't know why there are so many instances of Dr. Watson running.

Maybe for what I've noticed, there are some viruses that affects svchost.exe. It's possible because many viruses did delete win.com which is important on Windows XP and about your problem. Just re-install your OS.

Reinstalling is last resort.
