Lost System Files

[ltalbott]

I manually removed a trojan virus and now when my computer starts it works,
but says that I am missing two system files. What is the easiest way to put
those system files back?

If everyone else is having the same problem as I am (my crystal ball
is kinda foggy tonight) you'll need to provide the names of the
missing files.

Well without knowing what 2 files are missing, the only thing we will be
able to tell you is to follow the steps at this web page:

My system does not have either one of those files, but it boots fine.
Your manual removal was not thorough enough. Now, the fun part begins
because you need to find the
spurious reference to these files which causes the system to look for them.
Sorry, I can't help with this because
I have not had (yet) to solve such a problem.

Those are malware files, not system files. Since you didn't give details
about what trojan (and it is either a trojan or a virus, not both) you had
and how you removed it, please review the general malware removal steps
here:

If you were that thorough and are sure your system is really clean, then
manage your Startup to remove the references to the malware files. If you
weren't that thorough, it would be smart to go through the steps at the
above link.

Start>Run>msconfig [enter]

This brings up the System Configuration Utility. Look on the Startup tab and
find the probable culprit. Uncheck the box next to its name, Apply and OK
out. You don't need to restart immediately, but the next time you do you'll
get a dialog saying you've used the Utility. Just tick the box that says in
effect, "don't bother me about this again".

Important - Do not use the System Configuration Utility to stop processes.
Instead, use Start>Run>services.msc [enter] and do not stop any services
unless you really, really know what you're doing.
