How do I change a registry file without fear of messing up my computer?

Question

I work for a company that has an agreement with Norton Anti-virus that allows us to take home a copy of their virus detecting software (copied from work) to use at home. This helps to prevent us from bringing contaminated files from home into work and passing on any containation we may have at home. When I attempt to load the Norton Anti-virus software I get a message saying there is an old version of anti-virus software already loaded on the computer. I should remove the old software before continuing. The the installation is automatically terminated. I have seached and deleted anything and everything associated with Notron or anti-virus that either I or the computer can find. And still I get this message and the installation is terminated. I was told I can go into the regedit and look for AV files there. I did, and there are files that show up there. I will not remove anything there for fear of killing something that will end up giving me the "blue screen of death". Is there any script files availa ble or de-installation software availa ble that will clean up my comuter and allow me to install new anti-virus software? I am working at home with no protection right now and am frightened something will be sent to me that will comsume my computer harddrive.

Some direction or information would be appreciated.

Thanks

Norm

Here is the trick, COPY and save the reg edit file that you will be changing to a new location (for example to my documents folder) then if you erase or change any thing you can replace it with the original copy that was there before you started tinkering. GL
