I turned on my computer this morning and when it got to windows Norton came up and said it found nine new virus files, then norton shut itself down. When I try to open norton again, it stays up for about 30 seconds then shuts off. It said it can't quarantine the files or delete them. The virus is a backdoor.optixpro.13. My firewall (zone alarm pro) keeps shutting down too. Anybody know what I can do? Any other virus software that would get rid of this for me?
