Kaspersky Anti Virus detected a Trojan and deleted svchost. When the PC restarted I had no internet connection and my task bar was missing. I tried to do a system restore but could not access it, also tried from command prompt but it failed saying something about system restore can not protect computer. Next step, I restored my registry, from a backup but when I restarted XP the message: stop c000021a {fatal system error} blue screen appeared. Next, I looked at your site and followed instructions under this problem heading. However, I've tried a repair with the CD but it doesn't recognise the partition. Please help.

First of all.
o.o
It deleted your services host?
I don't even know how to respond to that.

Secondly
Thats why you lost inet and taskbar, your SERVICES HOST WAS GONE!

Thirdly,
What do you mean you can't re-install?
When your in the gui for the install after booting from the CD, do you mean that it cannot find any hard drives?

Yes, it can find hard drives but when I select the partition it says "XP cannot recognise the partition you selected".
Should I delete this partition? Will I lose data? Is there any way I can repair, please?

Hmm.
I personally do not know of a way to not loose data.
I would just wipe it and move on.
My suggestion, delete it and re-create.
However, you can use tools such as Bart PE

or Knoppix (if your a linux buff)
http://www.knoppix.org/

to boot the machine and save your files before a wipe.
