How to uninstall completly three programs flaw drive.exe,
helpfork.exe, and mpeg.exe that are in a folder firstprogramhold. 
Also want to delete all registry entries. Not sure how it got on my
computer.

If these programs are just starting up when you start the computer,
you can run the following startup program:

http://www.mlin.net/files/StartupCPL_EXE.zip

It will list all the programs that start up on your computer. You can
uncheck any that relate to the programs you do not want.

This will prevent them from running, and they should not bother you.

Search all these files through Search\files or folders from your start
menu and delete them manually. Like for Example your search criteria
follows as drive*.*, helpfork*.* and so on.
After successfully deleting all the files related to it, then run
regedit program and search for all the registeries in the same manner
as you did before and delete them manually.
I think this will solve your problem

You must use the regedit program "start->run->regedit.exe" to search
these entries in the registry

select edit-search and look for drive.exe, mpg.exe .... and delete all
the entries that you found.

First you can do a backup of the registry with Registry->Export and
restore-it with Registry->Import.

Actually you can use norton system works, they have an untilitie to
houekeep unwanted software page as well as exe file. These program
will housekeep the registry as well. Please go to www.norton.com to

the problem that you had. Thanks
