Yes, I did do it; but upon looking at it again; I had forgotten to add the .reg but I did it again with that.  However, upon trying to install again, I got the same error message.  Do you think rebooting my computer again would help?

This link should help remove ZA.

Thanks for that advice.  Like I said, I thought I had uninstalled Zone Alarm;but I did as you said and found a lot of files that you listed and I deleted them.  I thought this would have solved my problem, but when I tried to install avg7.5 free again, I got the same error message saying that "Another antivirus/security product is currently installed on this computer!"  It continues to say that it is not advisable to have more than one antivirus product running on the same computer and recommends that I cancel the installation and uninstall the current antivirus product.  The problem is I don't know what the product is or how to uninstall it.

Did you try this step in link provided?

 

REGEDIT4

 

[-HKEY_CLASSES_ROOT\ZAMailSafe]

 

[-HKEY_CURRENT_USER\Software\Zone Labs]

 

[-HKEY_LOCAL_MACHINE\Software\Zone Labs]

 

[-HKEY_USERS\.DEFAULT\Software\Zone Labs]

I did reboot, but still the same error message.  How can I find out what antivirus product it is?

You may be infected,try avg anti spyware in safe mode.

These are the files:

 

DAntivirus.cfg  (4 instances of this one)

 

Antivirus.Evt

 

Do you think it would be harmful to continue with the installation even though I get this error message?  It says it MAY be harmful.

You may have remnants of the original antivirus that came on your system when you got your DELL

 

More than likely it is either Mcafee or Norton

 

here are two tools you can run to remove either completely from the system and try again. Both downloads are from Majorgeeks and are safe.

 

MCPR (mcafee)

SymNRT (norton)

I am not which one to run but you can run both is you wanted to.. make sure to have a system restore point done before just in case... but this should help you install AVG free with no issues.
