I use ZA Security Suite version 9.1.507 for an XP enviroment. Long time user of ZA. I update and scan weekly.

For the past 7 months: my virus statistics show "0 viruses treated".

This can't be true can it? My system seems to be slowing down everyday and seems to change things on its own. My laptop is only 1 year old.

Should I be concerned that ZA is not working properly or set up incorrectly?
