Registry hives control virtually every aspect of your operating system. From
the hardware that's installed, per user and machine wide settings.
Restoring to a completely infection free set of registry hives can be of
help, but you may lose functionality if hardware drivers were changed since
then, and there are always other startup vectors, such as the Startup folder
in the Start Menu for malware to execute.
Your best bets are:
1) Boot the computer in Safe Mode to run your malware removal tools. Safe
Mode stops the vast majority of exploitable startup vectors from executing,
so most malware won't be running.
2) In conjunction with step 1, locate a good anti-virus/malware package
that doesn't require installation (can be run from a single command prompt)
to clean your system.
3) Use offline tools such as Bart's PE or Ultimate Boot CD to boot your
system. Then you can still access tools like Regedit and various
anti-virus/malware tools that can be added as add-ins to clean your system
of infections.
4) Back up your data that you can't afford to lose, format and start over,
ensuring that you have reputable anti-virus/malware tools installed, as well
as the use of either the built-in XP firewall, all security patches to date
and that you practice "safe hex". Simply put, make damned sure you know
what a file does, where it came from and scan it before you even think about
runnig it.
