trouble with firewall and antivirus

Hi I am having problems with my norton personal firewall and antivirus 2003.
After I had received an email my firewall and antivirus won't load. I even went to start then to the programs and it started to bring them up but then quit right away bringing them up. I can't even uninstall them to reinstall to get them working. I have a compaq presario running windows 98se. I put in the antivirus cd in and booted from there to check for viruses but it didn't find anything. If anyone has any suggestions I would greatly appreciate it.
thankyou in advance.

How long has it been since you last got "the email" that caused this?

 

sorry it took so long for me to get back. I fixed the problem somehow in my startup list my ccregvfy got checked and when i went and unchecked it everything started to work again. thanks again for responding. like i said sorry it took me so long to get back to you but it has been a very busy week.

thanks
