can't delete registry entries

I'm trying to clean up after a virus infection on an XP Pro SP2 machine. I
have a list of all the registry entries added by the virus, and want to
manually delete them. I can find them easily enough, but when I try to
delete them I get an 'unable to delete all occurrences' message (or words
very similar!).

I'm not very experienced in editing the registry - I usually use a util to
keep it tuned - and I know how dangerous it can be. But although I've
removed the virus exe from the machine, and prevented firewall_anti from
loading or running, I still have all these registry entries that I'd like to
get rid of. What's the right way to do it please? I'm right-clicking the
reg entry concerned and choosing delete. Edit/Delete gives me the same
message. As I say, I have what seems like an accurate list of the reg
entries made by the virus (from Sophos).

Any pointers greatly appreciated, thanks

The simple answer might just be to import old registry that you know is
fine. If you have it. Otherwise I don't know. I had a similar problem
but with NOrton IS 2004.
